Great Men and Famous Women, Vol. 7 A Series of Pen and Pencil Sketches of the Lives of More Than 200 of the Most Prominent Personages in History However, dismissing all of these as the exception, the rule is that self-sterility is due, as has been said, to the lack of affinity between pollen and pistils produced on the vines of some varieties. Manual of American Grape-Growing A blossom having stamens and no pistil is a Staminate or Male flower.

Mendelism Third Edition Since two kinds of flowers are produced on the pecan, one bearing the pistils, the other stamens, the pollen must be transferred from the latter to the former in order that pollination may take place. The Pecan and its Culture But most insect-visited flowers have the stamens and pistils associated either in the same or in contiguous blossoms. The Elements of Botany For Beginners and For Schools Their dry and formal knowledge was without interest, mere lists of petals and pistils, a dried herbarium of plants that fell to pieces at the touch of the fingers.

Northern Nut Growers Association Report of the Proceedings at the 44th Annual Meeting Rochester, N.Y. August 31 and September 1, 1953 These never produce fruit, for pumpkins are simply enlarged and ripened pistils. Ontario Teachers' Manuals: Nature Study There are two types of pollenization, one where the pistil is fertilized by insects carrying sticky pollen; the other by movement of the wind carrying the pollen.
