Names
CLEISTOCHLAMYS Oliv. [family ANNONACEAE], in Journ. Linn. Soc. ix. 175.
Information
Flowers hermaphrodite. Calyx closed in bud (sepals connate), splitting across the apex into 2 or 3 unequal or equal valves. Petals 6 (seen only in unexpanded flowers); 3 outer ovate, valvate in æstivation, 3 inner rather smaller, imbricate in æstivation. Stamens indefinite (about 30); anthers sessile or subsessile, cuneate-quadrate, extrorse; the connective slightly dilated and truncate beyond the cells. Torus slightly convex. Carpels free, 6–8; ovary glabrous or nearly so, narrowed above into a short linear-oblong recurved stigma; ovules solitary, erect. Fruit-carpels oblong, obtuse, stipitate. A glabrous shrub. Leaves rather narrow obovate-oblong or oblong, penninerved. Flowers very small, axillary, sessile.
Notes
This plant was placed, with doubt, in the genus Popowia, by Mr. Bentham (Linn. Trans. xxiii. 470), who, however, had not seen flowering specimens. These have been since supplied by Dr. Kirk. The salient characters of the genus are, the connate sepals forming a calyx, at first closed; the imbricate inner petals, which, with the truncate stamens, place it in the tribe Uvarieæ, and the very small, usually solitary, axillary flowers.
