Calyx 5–10-cleft or parted, nearly as in the staminate flowers; but petals none or minute rudiments. The Manual of the Botany of the Northern United States Including the District East of the Mississippi and North of North Carolina and Tennessee 2012-04-12T02:00:30.140Z Persian walnuts are self-pollenizing if pistillate and staminate blossoms occur at the same time, but such usually is not the case. Northern Nut Growers Association Report of the Proceedings at the 43rd Annual Meeting Rockport, Indiana, August 25, 26 and 27, 1952 It had perfect flowers, or rather, both pistillate and staminate flowers on the same tree. Northern Nut Growers Association Incorporated 39th Annual Report at Norris, Tenn. September 13-15 1948 The tree was a vigorous grower and precocious in putting on nutlets, but to my knowledge never bore staminate blooms and over a period of several years matured only one nut. Northern Nut Growers Association Report of the Proceedings at the 44th Annual Meeting Rochester, N.Y. August 31 and September 1, 1953 Its staminate flowers come out too early in Connecticut. Northern Nut Growers Association, Report of the Proceedings at the Seventh Annual Meeting Washington, D. C. September 8 and 9, 1916. Flowers greenish, axillary, the fertile solitary or in pairs, peduncled, appearing with the leaves, the lower usually staminate only, fascicled or racemose along the base of the branches of the season. The Manual of the Botany of the Northern United States Including the District East of the Mississippi and North of North Carolina and Tennessee 2012-04-12T02:00:30.140Z The catkin begins to take on a brownish color and at length the whole catkin, in case it is staminate, drops off. Northern Nut Growers Association Report of the Proceedings at the 43rd Annual Meeting Rockport, Indiana, August 25, 26 and 27, 1952 The staminate or pollen-producing flowers of all these species arise from lateral buds on shoots that grew the previous year. Northern Nut Growers Association Incorporated 39th Annual Report at Norris, Tenn. September 13-15 1948 This had a full crop of flowers this year, both staminate and pistillate. Northern Nut Growers Association Report of the Proceedings at the Fifteenth Annual Meeting New York City, September 3, 4 and 5, 1924 These staminate flowers are nearly perfected the season previous, and a few warm days in spring will bring them out, even before any leaves appear. Mysteries of Bee-keeping Explained Achene ovate, compressed, erect, partly or nearly naked.—Stingless, mostly glabrous and low herbs, with opposite leaves and united stipules; the staminate flowers often mixed with the fertile. The Manual of the Botany of the Northern United States Including the District East of the Mississippi and North of North Carolina and Tennessee 2012-04-12T02:00:30.140Z Professor Smith: I was struck by Mr. Pomeroy's statement that after apparent killing of the staminate bloom by frost the pistillate blossoms appeared and he had a crop. Northern Nut Growers Association, Report of the Proceedings at the Fourth Annual Meeting Washington D.C. November 18 and 19, 1913 With the European varieties the staminate or the pistillate flowers or both are likely to be killed by winter temperatures. Northern Nut Growers Association Incorporated 39th Annual Report at Norris, Tenn. September 13-15 1948 Best of all varieties called seedless, but the large staminate tree nearby spoils that feature. Northern Nut Growers Association Report of the Proceedings at the Fifteenth Annual Meeting New York City, September 3, 4 and 5, 1924 Now it is absolutely essential that pollen from the staminate flowers shall be introduced into the pistillate to produce fruit; because if a failure occurs in this matter the germ will wither and die. Mysteries of Bee-keeping Explained Flowers of two kinds in separate heads, the one pistillate, the other staminate. The Manual of the Botany of the Northern United States Including the District East of the Mississippi and North of North Carolina and Tennessee 2012-04-12T02:00:30.140Z This seedling tree, however, had a great many pistillate blossoms, which received pollen from the neighboring variety that was prolific in staminate bloom. Northern Nut Growers Association, Report of the Proceedings at the Fourth Annual Meeting Washington D.C. November 18 and 19, 1913 The spikelets are usually four-glumed and contain one terminal perfect flower and a staminate or neutral flower below. A Handbook of Some South Indian Grasses There are times when the pollen of the staminate plant is all shed before the pistillate gets ready. Northern Nut Growers Association Report of the Proceedings at the Fifteenth Annual Meeting New York City, September 3, 4 and 5, 1924 Craig, Brag and Comet, the only ones which have borne staminate flowers do not seem too hardy in the catkins however. Northern Nut Growers Association Report of the Proceedings at the Thirty-Eighth Annual Meeting Guelph, Ontario, September 3, 4, 5, 1947 Fertile flowers 1–5, the corolla none or reduced to a tube; staminate corolla funnel-form. The Manual of the Botany of the Northern United States Including the District East of the Mississippi and North of North Carolina and Tennessee 2012-04-12T02:00:30.140Z The reason a five or six-year-old Persian walnut tree does not bear many walnuts is that there are no staminate catkins. Northern Nut Growers Association, Report of the Proceedings at the Fourth Annual Meeting Washington D.C. November 18 and 19, 1913 In some grasses the spikelets contain only staminate or pistillate flowers. A Handbook of Some South Indian Grasses Both staminate and pistillate buds of filberts above the snow were practically all destroyed. Northern Nut Growers Association Report of the Proceedings at the Fifteenth Annual Meeting New York City, September 3, 4 and 5, 1924 It has had many staminate catkins for several years. Northern Nut Growers Association Report of the Proceedings at the Thirty-Eighth Annual Meeting Guelph, Ontario, September 3, 4, 5, 1947 It has one fault, however; the staminate blossom is abortive, never produces any pollen. Northern Nut Growers Association Thirty-Fourth Annual Report 1943 The staminate flowers are apt to be destroyed because they mature so late, and they may not carry any nuts. Northern Nut Growers Association Report of the Proceedings at the Second Annual Meeting Ithaca, New York, December 14 and 15, 1911 Each spikelet contains a single perfect flower and sometimes in addition a staminate flower just below the perfect flower. A Handbook of Some South Indian Grasses I have one Major pecan on shagbark that is over twenty-five feet high that has a very healthy appearance and that has shown staminate bloom for two or three years. Northern Nut Growers Association Report of the Proceedings at the Fifteenth Annual Meeting New York City, September 3, 4 and 5, 1924 It has an angular, creeping stem; large, somewhat heart-shaped, leaves; and axillary staminate or pistillate flowers. The Field and Garden Vegetables of America Containing Full Descriptions of Nearly Eleven Hundred Species and Varietes; With Directions for Propagation, Culture and Use. Evidently the staminate catkins necessary for pollen production are somewhat slower in appearing. Northern Nut Growers Association Thirty-Fourth Annual Report 1943 President Morris: No, I haven't seen any nuts; but they mature their wood, and if they mature their wood, they are likely to mature staminate and pistillate flowers. Northern Nut Growers Association Report of the Proceedings at the Second Annual Meeting Ithaca, New York, December 14 and 15, 1911 In fact, several of these larger grafted trees have been bearing staminate bloom for two or more years. Northern Nut Growers Association Report of the Proceedings at the Forty-Second Annual Meeting Urbana, Illinois, August 28, 29 and 30, 1951 The staminate flowers or catkins of a few varieties are definitely hardier than peach flowers. Northern Nut Growers Association Report of the Proceedings at the Twenty-Fifth Annual Meeting Battle Creek, Michigan, September 10 and 11, 1934 In many plants, however, such as the hemp, hop, sassafras, willow, and others, the staminate parts are on one plant and the pistillate parts are on another. Agriculture for Beginners Revised Edition Lancaster, very large, very vigorous tree, precocious, prolific, quality of nuts good but not best; staminate blossoms early, pistillate late. Northern Nut Growers Association Thirty-Fourth Annual Report 1943 Mr. Littlepage: While it is true they may mature staminate and pistillate blossoms, the question arises whether or not the growing season is going to be long enough at the end to mature the nuts. Northern Nut Growers Association Report of the Proceedings at the Second Annual Meeting Ithaca, New York, December 14 and 15, 1911 In two years it was observed, Niblack had staminate and pistillate flowering together one season, and staminate overlapping four days into the period of pistillate receptivity the next. Northern Nut Growers Association Report of the Proceedings at the Forty-Second Annual Meeting Urbana, Illinois, August 28, 29 and 30, 1951 Crosses in which the Persian walnut is the staminate or pollen producing parent may sometimes occur but if so, they have never come to the attention of the writer. Northern Nut Growers Association Report of the Proceedings at the Twenty-Fourth Annual Meeting Downington, Pennsylvania, September 11 and 12, 1933 Thus the staminate catkins sometimes fall before the pistillates form, and naturally there is no pollination and no crop. Walnut Growing in Oregon Some trees produce staminate flowers too early for proper pollination and thus do not yield a crop unless another good pollinator grows nearby. Northern Nut Growers Report of the Proceedings at the Twenty-First Annual Meeting Cedar Rapids, Iowa, September 17, 18, and 19, 1930 The plants themselves were growing beautifully, but most of the staminate blossoms or catkins were frozen, and, consequently, very little pollenizing was accomplished, and very little fruit the result. Northern Nut Growers Association, Report Of The Proceedings At The Tenth Annual Meeting. Battle Creek, Michigan, December 9 and 10, 1919 Most of them the result of placing bitternut hickory pollen on staminate butternut flowers. Northern Nut Growers Association, report of the proceedings at the eighth annual meeting Stamford, Connecticut, September 5 and 6, 1917 So far, it has been out of the question to hazard a reasonably safe assumption as to the staminate parent of all particular crosses by merely studying the botanical characteristics of the butterjap offspring. Northern Nut Growers Association Report of the Proceedings at the Twenty-Fourth Annual Meeting Downington, Pennsylvania, September 11 and 12, 1933 The staminate blossoms of this variety appear six weeks ahead of the pistillates and, there being no pollination, naturally there are no nuts. Walnut Growing in Oregon Their pistillate and staminate blossoms mature at the same time. English Walnuts What You Need to Know about Planting, Cultivating and Harvesting This Most Delicious of Nuts It is one of the first shrubs to blossom, the staminate flowers hanging in slender, graceful yellowish-brown catkins, while the pistillate flowers are little points of purplish-red protruding from the buds. Northern Nut Growers Association, Report Of The Proceedings At The Tenth Annual Meeting. Battle Creek, Michigan, December 9 and 10, 1919 Grafted upon the stock of a staminate common persimmon. Northern Nut Growers Association, report of the proceedings at the eighth annual meeting Stamford, Connecticut, September 5 and 6, 1917 The maples have lost their fleecy white softness, for the staminate flowers which were so beautiful in March have withered now. Some Spring Days in Iowa The Weschcke hickory has an abortive staminate bloom so that it must depend on some other variety for pollen. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin It is a singular fact that only the staminate varieties are injured, especially those which furnish considerable pollen, since this constitutes the chief food supply of both larvae and adults. Trees, Fruits and Flowers of Minnesota, 1916 Embracing the Transactions of the Minnesota State Horticultural Society,Volume 44, from December 1, 1915, to December 1, 1916, Including the Twelve Numbers of "The Minnesota Horticulturist" for 1916 When the crimson threads appear in the scaly buds the staminate catkins are lengthening, and soon the high wind shakes the golden pollen over all the copse. Some Winter Days in Iowa These staminate flowers produce pollen and then die. The First Book of Farming In the case of the hepatica acutiloba, however, it has been found that staminate flowers grow on one plant and pistillate flowers on another, hence insects are essential to the perpetuation of this species. Some Spring Days in Iowa Usually, after one day of exposure to bright sunlight, the staminate blooms will expand and begin to shed their pollen. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin The pistillate plants occupy separate but adjacent areas to the staminate ones.

The Gutenberg Webster's Unabridged Dictionary Section M, N, and O With some plants we find that not only are the pistils and stamens in separate flowers but the staminate and pistilate flowers are placed on different plants. The First Book of Farming Calyx of 4 or 5 petal-like sepals; no petals; stamens and pistils numerous, of indefinite number; the staminate and pistillate flowers on separate plants; the styles feathery, and more than 1 in. long in fruit. Wild Flowers Worth Knowing By following this procedure for several days with all the staminate blooms that have been gathered, the experimenter should have enough pollen for work on a small scale. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin Secondly, it is quite indifferent, how the two types are combined, or which of them is chosen as pistillate and which as staminate parent. Species and Varieties, Their Origin by Mutation The staminate flowers are still more showy on account of their great abundance, often giving a reddish-yellow tinge to the whole mass of foliage and filling the air with pollen. The Yosemite The staminate cones are seen growing straight downward from the under side of the young branches in lavish profusion, making fine purple clusters amid the grayish-green foliage. The Mountains of California The plant is so vigorous and hardy that, in combination with a fine staminate, it might be the parent of superior new varieties. Success with Small Fruits In the spring of 1940, three of these hybrids had pistillate flowers but no staminate blooms. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin The best way is to cultivate both types in alternate rows and to cut off the staminate panicles a few days before they open their first flowers. Species and Varieties, Their Origin by Mutation But if one set out a bed of Champions—another fine variety—well apart from any staminate kind, it would blossom profusely, but produce no fruit. The Home Acre Then it is laden with myriads of four-sided staminate cones about the size of wheat grains,—winter wheat,—producing a golden tinge, and forming a noble illustration of Nature's immortal vigor and virility. The Mountains of California As the Colonel Cheney is my favorite, in order to fertilize it, I plant alternate beds of some good staminate variety, Charles Downing, Triomphe, or Wilson. Success with Small Fruits On one of these plants, about one-foot high, I found staminate bloom which I consider unusual after only two seasons' growth. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin But the most curious fact is that it is only observed in staminate specimens; pistillate trees have not been found, although often sought for. Species and Varieties, Their Origin by Mutation How well I remember the disappointment and wrath of people who bought the plants at a high price, and set them out with no staminate varieties near to fertilize the pistillate blossoms. The Home Acre The staminate cones of all the coniferae are beautiful, growing in bright clusters, yellow, and rose, and crimson. The Mountains of California When both stamens and pistils are found in the same blossom, as is the case with most varieties, it is called a perfect flower, or staminate. Success with Small Fruits The staminate blooms of the Winkler hazel show similarity to those of both filberts and hazels. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin Each cluster has from 13-15 flowers, of which some are staminate and borne on stalks, while others are pistillate and nearly sessile. Species and Varieties, Their Origin by Mutation The blossom of the Jewell contains pistils only, and will produce no fruit unless a staminate variety is planted near. The Home Acre In cleft grafting walnuts is it necessary to use scions with only a leaf bud, or with staminate or pistillate buds? One Thousand Questions in California Agriculture Answered In a large field of pistillates, every tenth row should be of a staminate, blossoming at the same time with the pistillate. Success with Small Fruits We have two or three cases of male sterility in chestnut but in these no stamens are formed in the individual staminate flower. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin Proliferation of the inflorescence is very common and changes in the position of staminate and pistillate flowers are not rare. Species and Varieties, Their Origin by Mutation All danger of barrenness in pistillate kinds is removed absolutely by planting staminate sorts in the same bed. The Home Acre To them flies carry pollen from the staminate florets covering the rest of the spadix. Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors The Kentucky seedling is a first-class staminate, but it should not be used to fertilize the Crescent, since the latter would almost be out of bloom before the former began to blossom. Success with Small Fruits We have not named this variety as yet, although it has borne both staminate and pistillate bloom, it has never borne any ripe nuts. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin This being staminate, it has been propagated exclusively by cuttings. Species and Varieties, Their Origin by Mutation Some of the flowers were pistillate, some staminate,—a condition false to nature as regards the apple. The Journal of Abnormal Psychology, Volume 10 Calyx of 4 or 5 petal-like sepals; no petals; stamens and pistils numerous, of indefinite number; the staminate and pistillate flowers on separate plants; the styles feathery, and over 1 in. long in fruit. Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors If the pollen does not take hold, the spikes of the staminate blooms are sure to continue pink for a long time. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin The tree produces long racemes of red blossoms and its staminate blooms are catkins eight to ten inches long, which, when fully ripened, swish in the wind and release clouds of yellow pollen. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin Of course they cannot bear seed, and so it is with the sterile maize, which never produces any seed-spikes or staminate flowers. Species and Varieties, Their Origin by Mutation The few hermaphrodite florets have their styles protruding from the start, and incoming insects leave pollen brought from staminate florets on the early-maturing stigmas. Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors In the blossom's staminate stage, abundant pollen is collected by the hive bees chiefly; but, those of the Halictus tribe, the mining bees and the Syrphidae flies also pay profitable visits. Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors Within, tiny pistillate florets are seated around the base, while on the staminate plants the inflorescence extends higher. Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors Seemingly they have not been hardy although they have grown large enough to produce both staminate and pistillate blooms; they have never winter killed back to the ground, however. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin The shrub doubtless gives the small bees and flies their last feast of the season in consideration of their services in transferring pollen from the staminate to the fertile flowers. Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors On the smaller, less specialized bees and flies the vine depends in June to carry pollen from its staminate flowers to the fertile ones, whose thick, erect pistil would wither without fruiting without their help. Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors Some they transfer, of course, from the larger staminate flowers to the smaller pistillate ones as they crawl over one umbel of the carrion-flower, then alight on another. Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors The flowering spurge, having its staminate and pistillate flowers distinct, depends upon flies, its truest benefactors, to transfer pollen from the former to the latter. Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors If the wild hazel is to be used as the female, or mother, of the cross, it is necessary to pick off all the male blossoms, or staminate blooms. Growing Nuts in the North A Personal Story of the Author's Experience of 33 Years with Nut Culture in Minnesota and Wisconsin Another distinguishing feature is that its small, greenish-white staminate flowers grow on long, very slender pedicels; whereas the solitary fertile flowers are much nearer the stern. Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors Many kinds of bees, wasps, flies, and butterflies fertilize all these little flowers, which are first staminate, then pistillate, simply by crawling over them in search of nectar. Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors From Pennsylvania and Arizona, north to Nova Scotia and British Columbia, its amaranthine flowers are displayed from July to September, the staminate and the pistillate heads on distinct plants.
