31. Uvularia. 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. 



32. Oakesia. 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. 



33. Streptopus. 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. 



34. 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. 



35. Clintonia. 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.
