Description
|
Terrestrial or epiphytic perennial herbs; stems soft woody, short, erect, ascend- ing or repent, pubescent. Leaves opposite or rarely whorled, equal to strongly unequal in a pair, lanceolate, elliptic to ovate or orbiculate, green, pubescent, the veins often prominent; petioles usually present. Inflorescences racemose, cymose or capitate, usually extended beyond the leaves; peduncles short or elon- gated; bracts lacking; pedicels usually short. Flowers small; calyx with a cylindric or turbinate, often 10-costate tube, the lobes 5, short, erect, entire, pubescent; corolla yellow or white to reddish, occasionally spotted, the tube more or less erect in the calyx, cylindric to funnelform, the limb 5-lobed, spreading to pa- tent; stamens 4, included, in 2 pairs, the filaments adnate up to the middle of the corolla tube, staminode lacking; disc annular or semiannular; ovary superior. Capsule subglobose, membranous, dehiscing irregularly; seeds numerous, al- buminous (fide Bentham).

Note
|
includes 15 to 20 species of low growing, soft woody herbs. They are recognizable by the small congested flowers atop a usually elongate peduncle. Two species are known from Panama. One here noted as Cremosperma sp. A has been annotated by Wiehler and will presumably soon be published. The name Cremosperma probably refers to the albuminous seeds noted by Bentham.
