 erect. Stamens 8 the 4 alternate ones shorter ; anthers ellipti-

 olla slightly irregular. Petals widely expanded. Stamens in- 

 serted in a single series ; the filaments dilated below. Style at 

 first recurved. Stigma with four ultimately divergent lobes. 

 Capsule mostly linear-fusiform, many-seeded. Seeds fusiform,, 

 beakless, not papillate in one species. Cespitose perennials 

 from a stout caudex, bearing sessile scaly winter buds with terete 

 stems and ample leaves. 



E. spicatum Lam. Fl. France 1077. Stems erect, 2-6 feet high, sub- 

 simple, glabrate below : leaves lanceolate, acute, nearly entire, 4-8 inches 

 long, on very short petioles, thin pinnately veined, with the evident lateral 

 veins confluent in submarginal loops : infloresence elongated ; racemes 

 with small bracts ; young flower buds soon reflexed, but again spreading 

 or ascending before expansion : petals 5-7 lines long, style exceeding the 

 stamens, hairy at base; capsule 2-3 inches long; seeds less than a line 

 long, with very long dingy coma. Alaska to California, the Eastern States,.

E. latifolium. L. sp. 347. A span to afoot or more high, frequently 

 branched, mostly glabrate below; leaves 1-2 inches long; usually oppo-
