124 BOTANY. 



Var. GLOBOSUS. Glabrous ; flowers in dense globose heads, 4-8" in 

 diameter, the broad membranous involucrate bracts only sometimes apparent 

 in the fruiting specimens ; staminate flowers few and central, or occupying 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 inihe last, but the 

 segments more numerous (5-7 pairs) and pinnately incised, with linear- 

 oblong divisions, more or less scabrous-puberulent ; peduncles elongating in 

 fruit and exceeding the leaves ; rays 10-15, 4-6" long ; involucre none ; invo- 

 lucels of 6-8 linear acute leaflets ; flowers white ; calyx-teeth small ; fruit 2" 

 long, with 10 harrow somewhat corky wings ; carpophore 2-parted; vittas as in 

 the last, forming slight ridges in the broad intervals ; seeds involute. — Nuttall's 

 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.) 



Cymoptekus 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 ; vittse 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; cauline leaves near the base, resembling the radical ones; 

 peduncles 3-6' long; umbel of 8-12 unequal rays, without involucre;
