Captain Lewis:

. . . the pistillum is only one, of which, the germ [ovary] is triangular reather swollen on the sides, smooth superior, sessile, pedicelled, short in proportion to the corolla, altho' wide or bulky; the style is very long or longer than the stamens, simple, cylindrical, bowed or bent upwards, placed on the top of the germ, membranous shrivels and falls off when the pericarp has obtained its full size. the stigma is three-cleft, very minute, and pubescent. the pericarp is a capsule, triangular, oblong, obtuse, and triocular, with three longitudinal valves. the seed so far as I could judge, are numerous not very minute and globilar.—

Professor Reveal:

"The word 'germ' used here has been replaced by the term ovary."


pistil—"The female organ of a flower, composed of one or more carpels, and ordinarly differentiated into ovary, style, and stigma."
ovary (germ, in Lewis's day)—"The structure which encloses the ovules [seeds] of angiosperms; the expanded basal part of a pistil, containing the ovules."
superior ovary—"An ovary which is attached to the summit or center of the receptacle and is free from all other flower parts."
stigma—"The part of the pistil which is receptive to pollen."
style—"The slender stalk which typically connects the stigma to the ovary."
pericarp—"The wall of the fruit."
triocular—"With three locules."
locule—"A seed cavity (chamber) in an ovary or fruit; a compartment in any container."
valve—"One of the portions of the ovary wall into which a capsule separates at maturity."
