Leucosmia burnettiana is in all probability dimorphic. Thinks Gilia is truly heterostyled and Phlox subulata was, perhaps, once heterostyled. Has good evidence of heterostyly in 39 genera from 14 families.

Sends an informal title-page [for Orchids, 2d ed.].

Appreciates the condolences for Frank [on death of his wife, Amy].

Lithospermum longiflorum has cleistogamous flowers and, unlike other species of genus, it is not dimorphic.

Asked C. E. Bessey whether Lithospermum longiflorum was dimorphic like its relatives. Encloses CEB’s reply.

C. E. Bessey’s case [see 10969] came too late, as the sheets had been printed, but CD thinks it should be carefully investigated as a possible case of incipient heterostyly.

Is trying to make out the function of "bloom", the waxy secretion on leaves and fruits.

Has two young friends who wish to call on CD.

Has received CD’s book [Forms of flowers]; thanks him for the compliment of the dedication.

Thanks for AG’s review of Forms of flowers [Am. J. Sci. 3d ser. 15 (1878): 67–73].

Thomas Carlyle’s letter about CD was a forgery.

Gives Hermann Müller’s observations on Valeriana dioica.

Is unsure about function of "bloom"; are glaucous plants more or less common in arid parts of U. S.?

Observations on heliotropism.

Thomas Meehan reports that Linum perenne is self-fertile; CD thinks that he has mistaken the species.

AG’s review of Joseph Cook ["Lectures on biology", New Englander 37: 100–13].

Encourages CD to work at heliotropism.

Thinks Thomas Meehan is as "rattle-brained" as Joseph Cook.

[A damaged fragment cut from this letter is pinned to 11051.]

Heterostyly in Linum perenne. Believes the American form may be a distinct species.

Climbing plants.

Requests seeds of Echinocystis lobata for Hugo de Vries.

Requests seeds of Ipomoea and Megarrhiza for observations on seedling growth.

Is rereading MS of Movement in plants.

Will try to get Ipomoea and Megarrhiza seeds for CD.

Thanks for AG’s trouble about the seeds. Is curious to see their germination and the early seedling growth.

Asks for cotton seeds, as he observes odd movements of the cotyledon.

Sends some cotton seeds for CD.

Describes the germination and early growth of Megarrhiza about which AG has been misinformed. The tubular petioles act functionally like a root.

Ipomoea did not germinate.

Germination of Delphinium and Megarrhiza.

Germination of Megarrhiza. AG’s observations at variance with CD’s.

Seed germination.

Strange that his plants [of Megarrhiza] behaved differently from AG’s [see 12455].

Sends seeds of Megarrhiza and gives details of species.
