late-linear, sharply and irregularly serrate; racemes strict, at length some- 
what spreading, but scarcely secund ; heads smaller." Euby and Huntington 
Valleys and lower canons of the East Humboldt Mountains ; July-Septem- 
ber. (560.) 
SoLiDAGO GiGANTEA, Aiton. Saskatchewan to Oregon, and eastward 
from Canada to Alabama. Two forms were collected : — (a.) Leaves thin, 
smooth, distantly serrulate. On Poplar Creek, in the East Humboldt 
Mountains ; 6,500 feet elevation. (561.) (b.) Leaves thickish, often some- 
what scabrous above and on the veins beneath, broadly lanceolate, and the 
lower ones at least coarsely serrated. Stream banks throughout Nevada and 
in the Wahsatch; 4,500-6,000 feet elevation; July-October. (562.) 
SoLiDAGO occiDENTALis, T. & G. Sniooth ; stems 2-3^^ high, panicu- 
lately corymbose at the summit, leafy; leaves linear-lanceolate, obscurely 
3-5-nerved, minutely scabrous on the edges, the larger ones 4' long, 3" broad ; 
heads rather large, pedicellate in many small corymbs, broadly obconic ; 
involucral scales loosely imbricated in about 3 series, oblong-linear, the 
straight tips greenish, ciholate, rather acute ; rays 15-25, very small ; disk- 
llowers 10-15 ; achenia pubescent.— Oregon and California to the Rocky 
Mountains, (NuttalL) Big Bend of the Truckee, and on Soda Lake in Carson 
Desert, Nevada ; 4,500 feet elevation ; August. Very near to S. lanceolata 
of the east, which extends as far west as Kansas, but the latter plant has the 
branches and leaves considerably scabrous-pubescent, the heads narrowly 
oblong-clavate, and the involucral scales somewhat resinous and closely 
appressed. 247 Hall & Harbour, from the Nebraska plains, seems to be 8. 
occidentalis rather than S. lanceolata, though from its station one would look 
for the latter and not the former. (563.)

1-4^ high, with numerous virgate terete smooth and green, or puberulent- 
tomentose and whitish branches ; leaves narrowly linear, 1-nerved, 1-2' long, 
large, 5-flowered, in little clusters which are either corym-
