Maer June 1841.

[Drawing]

Rhod. azaloides foliage like Rhod. flower do but more delicate like Azalea, filament perfect, anthers little hard shriveled triangle with folds, so that if filled would have form of Anther of Rhod therefore every organ perfect except pollen itself—: aperture mere obscure slit. Scarcely rises higher than junction of filament (see drawing) sometimes turns up & is not parallel to filament as in 2. Carefully dissected under water not grain or rudiment of pollen. Stigma humid gummy & apparently perfect as in Rhod.

(N. B. Is not this perfection of stigma pistil general?)

Is it not analogous to stigma be resisting conversion into petals longer than the stamens in double flowers.)

Why anther is perfect only empty??!
