E. spicatum Lam. Fl. France 1077. Stems erect, 2-6 feet high, sub- 
simple, glabrate below: leaves lanceolate, acute, nearly entire, 4-3 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, 
Europe and Asia. 
E. latifolium. L. sp. 347. A Span to afoot or more high, frequently 
branched, mostly glabrate below; leaves 1-2 inches long; usually oppo-
