long) with six pairs of leaflets, the peduncles about equaling or exceeding 

 the leaves, and the hispidness of the calyx rather less dense ; flowers blue. 

 It is the H. capitatum, Var., of Whipple's Report, 1176 Brewer and 4928 

 Bolander from California, and 641 Fendler from New Mexico. Specimens 

 from the Wahsatch, near Salt Lake City, have oblong-leaflets, 1-2' long, 

 coarsely laciniate-lobed. (865.) Others from the West Humboldt Mount- 

 ains, Nevada, have broadly ovate leaflets, less than 1' long, often cordate at 

 base, the lobes few and short. (866.) 5-7,500 feet altitude ; May, June.

 ovate in outline, 2-3' long, upon elongated petioles, with about 2-3 pairs of 

 coarsely-lobed segments ; flowers in dense sessile or short-peduncled heads, 

 considerably shorter than the leaves ; calyx very hispid-pubescent ; corolla 

 blue ; root fasciculate. — Oregon and Washington Territory, (371 Fremont, 

 326 Geyer, &c.) In the canons of the Wahsatch, where it was also collected 

 by Stansbury ; 5-7,000 feet altitude ; June. (867.) 



Var. ALPiNUM. In dense clusters, the leaves concealing the almost sub- 

 terranean inflorescence, which is rather looser and with the more linear 

 lobes of the calyx less densely hirsute ; pedicels umbellate and occasionally 

 thickened toward the base, reflexed in fruit, some of the flowers abortive 

 and caducous. — East Humboldt Mountains, Nevada ; rocky ridge at 9,000 

 feet altitude ; July. (868.) 



Nemophila parvifloea, Dougl. Diffuse, more or less pilose through- 

 out with spreading hairs ; stems slender, decumbent or ascending, and with 

 the peduncles retrosely prickly ; leaves opposite or alternate, ovate in out- 

 line, pinnatifid, the 3-9 (mostly 5) lobes ovate or oblong, 1-6" long, acute, 

 entire or sometimes 1-toothed, the lower lobes more distinct; peduncles 

 about equaling the leaves, opposite to them when the leaves are alternate, 

 turned downward when in fruit ; appendages of the calyx very short, or 

 sometimes conspicuous ; corolla 1-2" long, scarcely exceeding the calyx, 

 tubular, 5-cleft, the obovate emarginate lobes often pilose at the apex ; lig- 

 ules 2 at the base of each filament, very small ; capsule somewhat hairy, 2" 

 in diameter, the placentae 2-ovuled, or in Var. pluriovulata, Torr., {N. pediin- 

 culata, Benth.,) with the seeds num,erous and tuberculate. — From Washing-
