318 UMBELLIFERiE. 



solitary erect freely branching stem 6 — 18 in. high, from a small roundish 

 not deeply seated tuberous root: leaves small, finely twice or thrice 

 pinnate, the ultimate segments small: umbels 1 — 4-rayed, small: fi. 

 yellow, the sterile ones long pedicelled : f r. broader than long, tiibercu- 

 late. — Rocky hills, in sterile clayey soil, in both the Sierra and the Coast 

 Range. Mar.- May. 



5. XRKkCXClX^ Bancroft. Perennials, glabrous or pubescent. Roots 

 thick, elongated, yellow, fragrant. Leaves mostly radical, pinnately or 

 ternately compound. Involucre sometimes wanting. Involucels con- 

 spicuous. Flowers yellow. Calyx-teeth obsolete or prominent. Fruit 

 somewhat flattened laterally, with prominent equal filiform ribs, and thin 

 pericarp. Oil-tubes conspicuous, 3 — 6 in the intervals, 4 — 10 on the com-

 oblong, 1-2 in. long, mostly confluent, coarsely and deeply mucronate- 

 serrate: peduncles 1—2 ft. high; umbel 16 20-rayed, usually without 

 involucre, but the umbellets subtended by linear-oblong reflexed bract- 

 lets; rays 2 i^ — 4 in. long; pedicels short: fr. nearly orbicular, smooth, 

 3—4 lines long, 1%—'^ lines broad, sharply ribbed. — Foothills of the 

 Sierra, from Butte Co. southward; also near San Francisco.

 1. c, under I'ehea. More slender than the last, mostly pulverulent : leaves 

 triternate; leaflets ovate, ^ — % in. long, usually 3-lobed: umbel 8 — 16- 

 rayed, mostly without involucre, the involucels of small linear bractlets; 

 rays 1 — 3 in. long: fr. 1 — 2 lines long, nearly as broad, retuse at base, the 

 ribs filiform. — Hills of the Coast Range, in wooded or open ground. 



3. A. Parishii, Greene. C. & R. Rev. Umb. 121 (1888), under Velxa. 

 Nearly acaulescent, 1 ft. high, glabrous, somewhat fleshy: leaves ternately 

 pinnatifid; segments ovate, irregularly lobed and cuspidate-toothed, the 

 margins revolute: umbel about 20-rayed, with no involucre, but involu- 

 cels of a few setaceous bractlets; rays 2 in. long or more; pedicels about 

 4 lines: calyx-teeth prominent: fr. glabrous, 3 lines long, with prominent 

 ribs. Of the South chiefly, but reaching our limits in Tulare Co., at

 pound leaves only 1 — 2 in. long; segments crowded and confluent, only
