 acuminate, cordate and clasping at base, 512 cm. long, usually glaucous, 

 especially beneath; flowers solitary in the upper axils; pedicels bent at the base 

 and geniculate in the middle, so that the flower is concealed by the leaf; 

 perianth narrowly campanulate, the segments greenish, lanceolate, acuminate, 

 strongly curved outward; anthers acuminate; berry oblong-globose, red, about 

 1 cm. in diameter. 



Common along streams and in springy places. 



Streptopus curvipes Vail. Stems simple, 10-30 cm. tall, from creeping 

 rootstocks; leaves oblong-lanceolate, acuminate, sessile, glabrous or sparsely 

 pubescent, ciliate; perianth rose-colored, 8 mm. long; fruit globose, at length 

 red.

 3-lobed. 



Xerophyllum tenax (Pursh) Nutt. Pine Lily or Bear Grass. Basal leaves

 branching, scaly below, leafy above; leaves alternate, somewhat 

 unsymmetrical, sessile or clasping; flowers terminal, drooping, 

 whitish or greenish-yellow, solitary or few in simple umbels; 

 perianth-segments 6, narrow, equal, separate; stamens 6, hy- 

 pogynous; ovary 3-celled; ovules 2 or sometimes several in each 

 cavity. 



Perianth broad at base. D. smithii. 

 Perianth narrowed at base. 



Fruit ovoid, pubescent; stigma entire. D. oreganum. 



Fruit globose, papillose; stigma 3-cleft. D. majus. 



Disporum smithii (Hook.) Piper. Stems 30-90 cm. tall; leaves ovate or 

 ovate-lanceolate, acute or acuminate, scarcely cordate at base; perianth bell- 

 shaped, broad at base, the segments erect; style 3-clcft; fruit oblong-ovoid, 

 glabrous, except the blunt beak. 



Along the coast, Nootka Sound, where it was first collected by Menzies, 

 to northern California.
