CATALOGITE. 123 



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-lJ" long, and the stems subpubes- 

 cent. (447.) 



Cymopteeus^ 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 6-7 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. alpinus, 

 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.) 



Cymopteeus montanus, Nutt. ^ Stem usually solitary 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. 



' CYMOPTEEUS, Eaf. Calyx-teeth rather prominent and setaceous or lanceolate, minute or 

 obsolete. Petals ovate, oblong or oblanoeolate, inflexed, quasi-emarginate. Disk flattened around tbe 

 styles, undulate-margined. Fruit ovate or elliptical, obtuse or retuse, subterete or slightly compressed 

 dorsally ; carpels semiterete ; ribs thick and elevated, all or only the lateral ones or those opposite to the 

 calyx-teeth expanded into wings ; vittse numerous, narrow. Carpophore 2-parted, free or attached to 

 the carpels. Seeds much compressed dorsally and more or less concave on the face.— Perennial and sub- 

 eaespitose, with a thickened caudex ; leaves pinnately decompound with narrow small or incisely pinna- 

 tifid segments ; umbels compound, usually few-rayed ; involuoral bracts 1-2 or none, of the involucels 

 several, very narrow or broad and membranous ; flowers white or yellow. Benth. & Hook.
