CATALOGUE. 125 



involucels of several lanceolate bracts; flowers yellow, with prominent 

 lanceolate calyx-teeth ; fruit 3-4" long, with one carpel often abortiye, the 

 perfect one with 3-5 rather narrow nndulate membranous wings (the 

 middle or intermediate ones often wanting;) vittse numerous, 3-4 in the 

 intervals and 6-10 upon the commissure ; carpophore free, 2-parted ; seed 

 concave. — Allied to C. tereUnthinus, which is a stouter plant with rigid 

 coarsely dissected leaves; Eastern Oregon, (Nuttall;) Sierras of California, 

 (Brewer.) Found in the Virginia and West Humboldt Mountains, Nevada ; 

 6-9,000 feet altitude ; May-September. (452.) 



Cymopterus (!) ANISATUS, Gray. Proc. Acad. Phil, Mar. 1863, p. 63. 

 Acaulescent, csespitose from a much-branched caudex, glabrous ; leaves 4^6' 

 long, narrow, on long petioles, somewhat rigid, pinnate, the leaflets 6-10 

 pairs, pinnately parted ; segments entire or laciniately lobed, linear, pun- 

 gently acute ; scapes equaling or exceeding the leaves, 6-12' high ; rays 

 8-12, unequal; involucre usually none; involucels of 6-8 linear-subulate 

 leaflets, equaling the white flowers ; calyx-teeth conspicuous, linear-subulate, 

 foliaceous; fruit 2" long, irregularly winged, the lateral ribs and one dorsal 

 one usually broader, rather thick and not membranous ; vittas obscure, one 

 in each narrow interval, 2-4 on the commissure; seeds sljghtly concave, 

 somewhat crenately sulcate under the dorsal intervals. — This is 157 Parry 

 (1861) and 222 Hall & Harbour from Colorado, its determination still left 

 doubtful. The nearly mature fruit now collected would rather place it in 

 the genus Seseli but for the too prominent wings. Found in the East Hum- 

 boldt Mountains, Nevada, and in the Wahsatch ; 8-9,000 feet altitude ; July, 

 August. (453.) 



LiGusTicuM APiiFOLiUM, Benth. & Hook. (Cynapium, Nutt.) Stems 

 2-4° high, terete, leafy or naked, branching towards the summit, with 2-4 

 umbels on long peduncles; leaves pinnately decompound, the segments 

 incisely lobed, acute ; cauline leaves ternate, upon a short dilated sheath ; 

 involucre none ; involucel few-leaved, lateral ; calyx-teeth obsolete ; the 

 stylopodia rather prominent, with a somewhat dilated crenate margin ; fruit 

 2i" long, oval, with acutely oarinate ribs ; seeds concave on the face, with a 

 central longitudinal ridge. — Oregon, California, and Colorado ; probably 

 throughout the Eocky Mountain region. In the "Wahsatch and Uinta Moun-
