involiicels of several lanceolate bracts; flowers yellow, with prominent 
lanceolate calyx-teeth ; fruit 3-4" long, with one carpel often abortive, the 
perfect one with 3-5 rather narrow luidulate 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. terehinthinus, 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,^. 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 ; vittae obscure, one 
in each narrow interval, 2-4 on the commissure; seeds slightly 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 sunniiit, 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 crenatc nuirgin ; fruit 
2h" long, oval, with acutely carinate ribs; seeds concave on the face, with a 
central longitudinal ridge. — Oregon, CaUfornia, and Colorado; probably 
throughout the Rocky Mountain region. In the Wahsatch and Uinta Moun- 
tains ; 8-9,000 feet altitude ; with immature fruit, July and August. (454.)
