My dear Gray,
Thanks for the card about Pontederia, & I have written to Mr Leggett.1 I am going to trouble you once again but I honestly believe for the last time. In a letter dated Nov 21, 1870 you say that Phlox subulata presents two forms which have been named as species & which you are inclined to think is a case of di or tri morphism: you speak of this as a common species, & if so could you send me two or three dried flowers of the different forms that I might compare their pollen grains & stigmas.2 In the same letter you mention Gilia aggregata (pulcella) with the stamens & pistils varying much in length; I suppose this is a rare plant; but if not so, I should much like to examine the two forms.—3
Forgive me & believe me | Yours very sincerely | Ch. Darwin
