to M. Bolanderi, Gray, but there is so much variation in pubescence, in the 
size and section of the leaflets, and in the length of the fruiting pedicels that 
there seems hardly place for distinction. An original specimen of Nuttall's 
in Herb. Torr. has the pedicels but 1-1^" long, and the stems subpubes- 
cent (447.) 
Cymoptekus^ nivalis. Caudex long and branching ; minutely scabrous- 
puberulent or subglabrous, glaucous ; leaves simply pinnate with the leaflets 
3-5-lobed or pinnately dissected, the segments oblong-lanceolate, acute or 
mucronate ; scape exceeding the leaves, 2-4' high, with a single small nearly 
capitate umbel ; involucre none ; involucel 1-sided, of 5-7 broad obtuse 
membranous bracts, united at base, and nearly equaling the white or pinkish 
flowers ; calyx-teeth short and obtuse ; wings equal, thin. — Near C. nlpinus, 
but distinguished by the involucels, the smaller and more compact umbels 
of white flowers, and the comparatively thin, less corky wings. East Hum- 
boldt Mountains, Nevada; 9-10,000 feet altitude ; July, August. (448.) 
Cymopterus montanus, Nutt. Stem usually sohtary from a fleshy root, 
erect, sheathed at base, 1-2' long; leaves glaucous, glabrous or somewhat 
scabrous-puberulent, bipinnately divided, the segments (about 3-4 pairs) 
oblong, somewhat incised, obtuse and submucronulate ; peduncles usually 
shorter than 'the leaves ; involucre and involucels somewhat campanulate, 
scarious, about 5-parted, the segments obovate and obtuse, entire or 3-5-cleft, 
with greenish ribs; flowers white, polygamous; calyx-teeth small, ovate; 
fruit about 3" long ; carpophore persistent, 2-parted ; wings 6-10, broad and 
membranous, often unequal ; seed more or less involute. — An abnormal form 
was collected by Beckwith on the Goshoot Mountains, Utah, having 10 
spongy wings on the upper part of the ovary extending beyond the flower, 
the stamens reduced to rudiments, petals 2-3, of an unusual form, the styles 
conspicuous but without stigmas. The species extends from Western Texas 
to Arizona and north to Colorado and Montana. 
' CYMOPTERUS Raf. Calyx-teeth rather prominent and sotaoemiH or lanceolate, minute or 
obsolete. Petals ovate, oblong or oblanceolate, inflexed, quasi-emargiuate. Diak flattened around the 
styles, undulate-margined. Fruit ovate or elliptical, obtuse or retuse, subterete or slightly compressed 
dorsallT ; carpels semiterete ; ribs thick and elevated, all or only the lateral ones or those opposite to the 
calyx-tieeth expanded into wings; vittaj numerous, narrow. Carpophore 2-parted, free or nttarlu d to 
the carpels. Seeds much compressed dorsally and more or less concave on the face.-Perenu.al aiul sub- 
cajspitose, with a thickened caudex ; leaves pinnately decompound with narrow small or iucisely pinna- 
tifid segments; umbels compound, usually few-rayed ; involucral bracts 1-2 or none, of the involucels 
several, very narrow or broad and membranous ; flowers white or yellow. Benth. & Hook.
