Streptopus amplexifolius (L.) DC. Stems branched, about 1 m. tall, 

 from horizontal creeping rootstocks, glabrous except at the base; leaves ovate, 

 acuminate, cordate and clasping at base, 5-12 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. 



In the mountains, common at low elevations. 



124. XEROPHYLLUM. 



Perennials with a short thick woody rootstock and numerous 

 radical stiff linear leaves; perianth white, of six separate spread- 

 ing petal-like segments; stamens 6, at the base of the perianth- 

 segments; styles distinct, linear, reflexed; ovary sessile, ovate, 

 3-lobed. 



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

 very numerous, harsh and stiff, linear, keeled, 5 mm. broad, 60-90 cm. long; 

 cauline similar but smaller and ciliate at base; stems stout, 1-2 m. tall, stiff 

 and erect; flowers white; raceme dense, at first pyramidal, then elongating, 

 15-40 cm. long in bloom, longer in fruit; pedicels spreading in flower, erect in 

 fruit, 2-3 cm. long. 



Common in open woods, especially in the mountains, but not known to 

 occur on Vancouver Island or in western British Columbia. 



125. DISPORUM. 



More or less pubescent herbs with slender rootstocks; stems 

 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-cleft; fruit oblong-ovoid, 

 glabrous, except the blunt beak. 



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

 to northern California. 



Disporum oreganum (Wats.) B. & H. Stems 30-80 cm. tall, branched;
