104 ERYTHEA. 



habit, smaller spikelets and very unlike leaves. Although the 

 plant occurs widely separated from the range of D. spicata R. & S., 

 it is scarcely more than a variety of that species, differing mainly in 

 character of pubescence. 



Trillium crassifolium. About 2 dm. high, from an erect 

 root-stock, 2-3 cm. long ; leaves ovate, not at all rhombic, 4-5 cm. 

 long, 2-4 cm. wide, thickish (chartaceous when dry), abruptly 

 acuminate near the apex, sessile by a broad base; pedicel erect, 

 about 1 cm. long; petals white or pinkish, broadly to rather 

 narrowly lanceolate, acuminate or acute, scarcely as long as the 

 sepals, 2-2.5 cm. long; sepals narrowly or broadly lanceolate, acute. 



On damp hillsides, foot-hills near Wenatchee, 30 April, 1899, 

 Kirk Whited. Near to T. ovatum Pursh, from which it differs in its 

 erect rhizomes, shorter petals, and thickish differently shaped leaves. 

 The specimens are in young flower only, but in the dried plants the 

 petals are pinkish.
