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.

Perhaps you w
Leucosmia Burnettiana is in all probability dimorphic judging from relative length & positions of stamens & pistils, but more especially from difference in the stigmas of the 2 forms, but the pollen-grains do not differ in size, which is the best evidence.—
Gilia pulchella: the two forms differ in their stigmas & do not differ
in their pollen-grains, & I sh
Phlox subulata is a devil incarnate & as bad as Rhamnus: perhaps it was once heterstyled, with the short-styled form since rendered more feminine in nature. Altogether I now know on fairly good evidence of 39 genera, in 14 Families, which include heterstyled species. This pleases me.
It is dreadful work making out anything about dried flowers; I never look at one without feeling profound pity for all botanists, but I suppose you are used to it like eels to be skinned alive.—
