BOTANY. 
Var. GLOBOSUS. Glabrous ; flowers in dense globose heads, 4-8" in 
diameter, tlie broad membranous involucrate bracts only sometimes apparent 
in the fruiting specimens ; staminate flowers few and central, or occu2:)ying the 
whole umbel ; fruit 5-7" long, with the wings 2-3" broad ; vittse 3 in the 
intervals, and 3-4 on each side of the commissure opposite to the edges of 
the strongly involute seed. — A well marked variety. Carson Valley and on 
the Virginia and Trinity Mountains, Nevada; 4,500-7,000 feet altitude; 
April, May. As in several other species of the genus, the root has an agreeable 
flavor and is gathered for food by the Indians in early spring. (449.) 
Cymopterus glaucus, Nutt. Caudex and leaves as in the last, but the 
segments more numerous (5-7 pairs) and pinnately incised, with linear- 
oblong divisions, more or less scabrous-pub erulent ; peduncles elongating in 
fruit and exceeding the leaves; rays 10-15, 4-6" long; involucre none; invo- 
lucels of 6-8 Hnear acute leaflets ; flowers white ; calyx-teeth small ; fruit 2" 
long, with 10 narrow somewhat corky wings; carpophore 2-parted; vittse as in 
the last, forming slight ridges in the broad intervals ; seeds involute.— NuttalFs 
description was drawn from young specimens, with which these accord 
exactly ; collected by him in northern Idaho. Found on the Battle and East 
Humboldt Mountains, Nevada; 7-7,500 feet altitude; June, July. (450.) 
Cymopterus longipes. As in the preceding, but the stem 4-6' high, 
and the fruiting peduncles exceeding the leaves, 4-10' in length; very nearly 
glabrous throughout ; segments of the leaves 3-5 pairs, somewhat pinnate, 
the divisions broadly oval and mucronulate ; involucre none or a single 
setaceous leaflet; involucels of 6-8 subulate acuminate somewhat scarious 
bracts; rays about 10, 4-10" long; flowers yellow; calyx-teeth small, ovate, 
obtuse; fruit 3-4" long; carpophore 2-parted; vittae broad and conspicuous, 
3-4 in the intervals and 3 on each side of the commissure; wings 10, broad 
and scariously membranous, somewhat unequal; seed very strongly involute, 
sometimes even terete by the meeting of the opposite edges.— Wahsatch 
Mountains near Salt Lake City, and on Antelope Island ; 5,000 feet altitude ; 
May, June. (451.) 
Cymopterus fceniculaceus, Nutt. Glabrous ; stems very short, from 
a branching and spreading caudex ; leaves mostly radical on rather long and 
slender petioles, pinnately decompound, the segments short and linear, 
acuminate; cauHne leaves near the base, resembling the radical ones; 
peduncles 3-6' long; umbel of 8-12 unequal rays, without involucre;
