Wild Flowers An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors Watson and Professor Asa Gray, as they inform me; but who will pretend to say that they do not vary as much as the individual plants of the same sub-variety of wheat? The Variation of Animals and Plants under Domestication — Volume 1 In Gymnadenia tridentata, according to Asa Gray, the anther opens in the bud, and the pollen being somewhat coherent falls on the stigma and on the rostellum which latter is penetrated by the pollen-tubes.

The Movements and Habits of Climbing Plants I have asked Asa Gray for seeds, to whom I have mentioned your observations on rostellum, and asked him to look closer to the case of Gymnadenia. More Letters of Charles Darwin — Volume 2 Asa Gray 'American Journal of Science' 1865 page 101 and elsewhere as already referred to. The Different Forms of Flowers on Plants of the Same Species I believe you think with Asa Gray that I have not allowed enough for the stream of variation having been guided by a higher power. More Letters of Charles Darwin — Volume 1 How splendidly Asa Gray is fighting the battle. Life and Letters of Charles Darwin — Volume 2 Professor Asa Gray, in a paper already quoted, first noticed the extreme sensitiveness and rapidity of the movements of the tendrils of certain Cucurbitaceous plants. The Movements and Habits of Climbing Plants Asa Gray says ducts are very early developed, and it seems to me wonderful that they should pursue this course. More Letters of Charles Darwin — Volume 2 Asa Gray has seen flowers on exotic plants in the Northern United States which never expanded and yet fruited.

The Origin of Species by means of Natural Selection, 6th Edition Do you know Asa Gray's child book on the functions of plants, or some such title? More Letters of Charles Darwin — Volume 2 Professor Asa Gray remarks with respect to this plant: "the tendency to dimorphism, of which there are traces, or perhaps rather incipient manifestations in various portions of the genus, is most marked in G. aggregata." The Different Forms of Flowers on Plants of the Same Species I think he quotes from Asa Gray, certainly not from me; but I have neither A. Gray nor "Origin" with me.

Life and Letters of Charles Darwin — Volume 2 As Professor Asa Gray has remarked, "the spores and other reproductive bodies of many of the lower algae may claim to have first a characteristically animal, and then an unequivocally vegetable existence." The Origin of Species by means of Natural Selection, 6th Edition I wonder why Asa Gray will not believe in the quaternary arrangement; I had fancied that you saw some great difficulty in the case, and that made me think that my notion must be wrong. More Letters of Charles Darwin — Volume 2 Asa Gray speaks of the flowers of the American species as perfect, whilst those in the allied genus Celastrus are said to be "polygamo- dioecious." The Different Forms of Flowers on Plants of the Same Species I shall work the British flora with three separate Floras; and I intend dividing the varieties into two classes, as Asa Gray and Henslow give the materials, and, further, A. Gray and H.C. More Letters of Charles Darwin — Volume 1 There are very few remarks in your book to which I demur, but when you back up Asa Gray in saying that all instincts are congenital habits, I must protest. Life and Letters of Charles Darwin — Volume 2 Such characters are not of course of specific value, but they are, as Asa Gray has remarked in commenting on this memoir, such as generally enter into specific definitions. The Origin of Species by means of Natural Selection, 6th Edition Asa Gray says they present two forms like Primula. More Letters of Charles Darwin — Volume 2 This plant exists in the United States, as I am informed by Professor Asa Gray, under two hermaphrodite forms. The Different Forms of Flowers on Plants of the Same Species Asa Gray is fighting admirably in the United States.

Life and Letters of Charles Darwin — Volume 2 Writing to Asa Gray in 1856, Darwin gave a brief preliminary account of his ideas as to the origin of species, and said that geographical distribution must be one of the tests of their validity. Darwin and Modern Science Asa Gray's observations on the rostellum of Gymnadenia are very imperfect, yet worth looking at. More Letters of Charles Darwin — Volume 2 Plantago media does not present two forms; but it appears from Asa Gray's description, that such is the case with four of the North American species. The Different Forms of Flowers on Plants of the Same Species My kind friend Asa Gray often writes to me and tells me of the warm discussions on the "Origin of Species" in the United States. More Letters of Charles Darwin — Volume 1 I would bet even, or three to two, that it is Asa Gray, though one or two passages staggered me.

More Letters of Charles Darwin — Volume 1 I have got a plant of Echinocystis lobata to observe the irritability of the tendrils described by Asa Gray, and which of course, is plain enough. Life and Letters of Charles Darwin — Volume 2 A few years later Asa Gray found the explanation in both areas being centres of preservation of the Cretaceous flora from a common origin. Darwin and Modern Science I have added another very clever pamphlet by Prof. Asa Gray. More Letters of Charles Darwin — Volume 2 "Homely, honest, ungainly Lincoln," said Asa Gray, in a letter to Darwin, "is the representative man of the country." Lincoln; An Account of his Personal Life, Especially of its Springs of Action as Revealed and Deepened by the Ordeal of War The chief part of the article is made up of quotations from Asa Gray's article referred to below. More Letters of Charles Darwin — Volume 1 With the Arabs on the Nile, Professor and Mrs. Asa Gray concluded that nodding in affirmation was rare, whilst shaking the head in negation was never used, and was not even understood by them. The Expression of the Emotions in Man and Animals See Asa Gray, "Scientific Papers," 1889, Volume II., page 235, on "The Pertinacity and Predominance of Weeds," where the view here given is adopted. More Letters of Charles Darwin — Volume 1 But what makes me most object to Asa Gray's view is the study of the extreme variability of domestic animals. More Letters of Charles Darwin — Volume 1 By the way, I heard lately from Asa Gray that Wyman was delighted at "Man's Place." More Letters of Charles Darwin — Volume 1 In a letter received two or three weeks ago from Asa Gray he writes: "I read lately with gusto Wallace's expose of the Dublin man on Bees' cells, etc." More Letters of Charles Darwin — Volume 1 Mrs. Asa Gray saw an Arab managing his boat clumsily on the Nile, and when laughed at by his companions, "he blushed quite to the back of his neck." The Expression of the Emotions in Man and Animals I am so very glad you will come here with Asa Gray, as if I am bad he will not be dull. More Letters of Charles Darwin — Volume 1 Professor and Mrs. Asa Gray attended to some points in the expressions of the natives, as observed by them whilst ascending the Nile.
