COULTER AND ROSE—NORTH AMERICAN UMBELLIFERAE. 183 
puberulent at tip, the 3 to 5 thick carpel wings usually unequal, 
becoming narrower toward the base of the fruit; oil tubes several in 
the intervals, 8 or more on the commissural side. 
Type locality, ** Little Colorado, northern Arizona, growing in 
gravel;” collected by /unes; type specimen in Herb, Jones, duplicate 
in U. S. Nat. Herb. 
Northern Arizona and probably in Nevada. 
Specimens examined : 
Arizona: Little Colorado, Jones, June 10, 1890. 
Nevapa: Shockley, April, 1886, seems to be this species, but is not in fruit. 
Apt to be confused with C. globosus, which it very much resembles in general 
habit, but is distinct in its more finely dissected leaves with narrower segments and 
blunter teeth, larger and toothed involucellate bractlets, puberulent fruit, and numer- 
ous oil tubes.

Cymopterus montanus globosus Watson, Bot. King Sury. 124. 1871. 
Low (5 to 10 cm.) and glabrous, the cluster of few leaves and pedun- 
cles springing from a slender subterranean stem; leaves glaucous, 
pinnate or bipinnate, with broadly oblong pinnatifid segments; ulti- 
mate divisions rather broad, more or less cuspidate-toothed; rays and 
pedicels obsolete, the white flowers and fruit. being in dense globose 
heads, and the bractlets of the involucel small and linear, hidden among 
the flowers of the dense cluster; fruit 6 to 8 mm. long, obovate, the 5 
thick carpel wings approximately equal, becoming narrower toward 
the base of the fruit; oil tubes solitary in the intervals, 2 on the com- 
missural side and a small one in each wing. 
Type locality, ‘Carson Valley and on the Virginia and Trinity 
Mountains, Nevada, altitude 4,500 to 7,000 feet;” collected by Watson, 
no. 449; type specimens in U. 8. Nat. Herb. 
Valleys in the mountains of northern Nevada. 
Specimens examined : 
Nevapa: Near Carson City, altitude 1,500 meters, Watson 449 except fruit, April, 
1868; near Empire City, Jones 3885, May 20, 1882. 
A very rare species, having been collected but two or three times. 
6. Cymopterus fendleri Gray, Pl. Fendl. 56. 184%. 
Cymopterus decipiens Jones, Zoe 2: 246. 1891. 
Low (5 to 10 em.) and glabrous, the cluster of leaves and peduncles 
springing from a slender subterranean stem which arises from an 
elongated thick root; leaves usually exceeding the peduncles, 2 to 3- 
pinnate; pinnae and segments 5 or 7, oblong and incised; umbels with 
few and unequal rays and yellow flowers, sterile flowers with longer 
pedicels than the fertile; involucre represented by a short sheath whose 
teeth are occasionally prolonged into small linear bracts, and involu- 
cels of bractlets united at base and exceeding the flowers; fruit
