Uvurarisa. Flowers few (1 to 3), solitary, terminating the stem 
or leafy branches, pendulous, yellow; segments acuminate, ob- 
tusely gibbous and with a callus or ridge each side of the deep 
nectary. Anther-cells adnate to the prolonged connective. Styles 
united to the middle. Capsule coriaceous, depressed obovate, 
obtusely 3-lobed, loculicidal at the summit. Seeds 1 or 2 in 
each cell, globose, brown, half covered by a thin white aril. 
Stem terete, from a short rootstock with fleshy-fibrous roots. 
Leaves perfoliate, smooth on the margin. 
OaxkesiA. Flowers few, solitary, on short pedicels opposite the 
leaves, pendulous, yellow; segments obtuse or acutish, carinately 
gibbous and without callosities. Stamens and styles as in the 
last. Capsule membranous, elliptical, acutish at each end or 
shortly stipitate, triquetrous and acutely winged, very tardily 
dehiscent. Seeds 1 to 3 in each cell, globose, brown, with a 
very tumid spongy brown rhaphe. Stem acutely angled, from 
a slender creeping rootstock. Leaves sessile, clasping, with 
scabrous margins. 
Strepropus. Flowers more numerous, apparently axillary, 
the pedicel often geniculate upon a peduncle (a second or third 
pedicel and flower sometimes developed), pendulous, greenish- 
white or purplish; segments acuminate, recurved above. An- 
thers sagittate, on short deltoid or subulate filaments, acute or 
setaceously acuminate. Styles united. Fruit a reddish sub- 
globose slightly 3-lobed berry. Seeds few to many in each cell, 
oblong, longitudinally striate, light-colored. Leaves clasping. 
Prosartes. Flowers in fascicles (1—-6-flowered) terminating the 
branches, white or greenish, suberect or pendulous ; segments 
acute or acuminate. Anthers on slender filaments, oblong, 
obtuse, dehiscing laterally. Styles united. Ovules 1 to 3 pairs 
in each cell. Fruit a somewhat fleshy obtusely lobed reddish 
berry. Seeds subglobose to oblong, with very thin close light- 
colored testa. Leaves with reticulated veinlets. 
Cuintonra. Flowers solitary or umbellate upon a naked scape- 
like peduncle, white, greenish, or rose-colored, erect or nodding ; 
segments obtuse or acutish. Anthers on slender filaments, ob- 
long to linear, dehiscing laterally. Ovary 2-3-celled: styles 
united ; stigma 2—3-lobed (ovary 2-celled and stigma only slightly 
2-lobed in our species). Fruit a thin slightly lobed ovoid blue 
berry. Seeds smooth, brownish, crustaceous. Root-stock slender, 
creeping : leaves radical, large, oblanceolate, sheathing, ciliate.
