Description Flowers perfect, subsessile, with 1-3 bracts subtending 1-5 bracteate fertile and 0-4 bracteate sterile flowers. Sepals 5, discrete, hypogynous, concave, greenish white, with conspicuous midribs and membranaceous margins. Stamens 5, hypogynous or perigynous, basally connate forming an exappendiculate tube shorter than, but occasionally basally fused with, the ovary; free portions of the filaments longer than the tube, usually somewhat flattened; anthers 4-locellate, introrse, medially attached. Ovary globose or ovoid, 1-locular, 1-ovulate; ovules campylotropous, the filiform arillate funicles with central basal placentae; styles 1, stigmata 2 (-3). Fruit a utricle circumscissile near the middle; seeds cochleate- orbiculate, black. Erect or clambering glabrate or pubescent herbs or shrubs. Leaves alternate, entire, petiolate or subsessile, linear-elliptic to broadly ovate, attenuate, deciduous. Inflorescences of axillary and terminal glomerules, these racemosely or paniculately disposed, with or without foliar leaves.
Distribution This genus of perhaps five species, is chiefly a South and Central American genus with only one species ranging as far north as Mexico.
Note The closely related oriental genus Allmania has occasionally been treated as a subgenus but morpho- logically seems to deserve generic status. Two species of Chamissoa occur in Panama.
Key a. Terminal inflorescences pyramidal, the glomerules paniculately disposed; styles less than 1.5 times as long as the stigmata; ovary at anthesis tympaniform, truncate to the base of the style; sepals ovate, the outer more than 1 mm. broad; aril completely enveloping the seeds; seeds punctate....... ..... 1. C. ALTISSIMA aa.
