162 ERYTHEA. 



usually a single branch, equaling the campanulate tube : petals 

 filiform, 1-nerved, entire, or very rarely parted near the apex 

 into two or three lobes, slightly longer than the calyx : stamens 5, 

 very short. 



Wahsatch Mts., North Utah, alt. 5,000 ft., Watson, No. 365, 

 May, 1869. 



Var. Parryi. Smaller in every way than the species: scapes 

 2-3 dm. high, slender: leaves 2 cm. in diameter, darkly and con- 

 spicuously crenate, sparsely pilose ; petioles short, pilose : petals 

 more frequently parted at apex: Wyoming, Striking Water, Parry, 

 No. 102, in 1873 (type); Colorado, Trappers' Lake, alt. 9,500 ft., 

 Crandall, Aug. 13, 1894. 



Mitella micrantha. Scapes stoutish, flexuous, 1.5-4 dm. high, 

 sparsely pubescent below, glandular puberulent above : leaves ovate 

 or orbicular, reniform, usually quite prominently 5-lobed, faintly 

 crenate, glabrous or sparsely pilose on each side, ciliate with scat- 

 tered hairs, 2-6 cm. long, thickish ; petioles twice as long, glabrous 

 or pilose: raceme 2-10 cm. long, the flowers irregularly scattered, 

 not secund: flowers 6-15, whitish, nearly sessile, ascending, 1.5 mm. 

 long : calyx-lobes oblong, obtuse, 3-nerved, the nerves all simple, 

 the lobes equaling the campanulate tube: petals oblanceolate, entire, 

 acuminate, 3-nerved in the widest part, exceeding the calyx-lobes: 

 stamens short, included. 



Fort Colville, Washington, Watson, No. 135, Sept. 29, 1880. 



Mitella diversiloba, Greene, Pitt. I. 32. In addition to the 

 characters in the original description, the following additional ones 

 appear noteworthy: calyx-lobes acute, mucronate, the raidnerve 

 simple, the lateral ones branched : petioles incurved : flowers not 

 secund, 2 mm. long: scape usually naked, but sometimes bearing a 

 single leaf near the base. 



We have not seen the type, but the species would seem unmis- 

 takable in its peculiar foliage, as well as the floral characters. 

 Specimens examined: N. W. California, iJattan, in 1879; Wash- 

 ington, White Salmon River, Suhdorf, No. 13, 21 May, 1881. 



ilitella anomala. Scapes naked, slender, 3-4 dm. high, mi- 

 nutely puberulent: leaves orbicular, 5-veined, scarcely lobed, reniform 

 with a broad sinus, doubly crenate, sparsely pilose above, glabrous 

 beneath, ciliate, 2-4 cm. broad; petioles slender, glg,brou8, or
