Var. nudicaule, Gray, 1. c. Leaves all in the radical tuft, or only one or two very 

 small and bracteiform on the (8 to 12 inch high) glabrous scape. — Northern Sierra Nevada, 

 California, Lemmon, Mrs. Austin, the latter on Lassen's Peak. 



++++++ Flowers apparently yellow, only 5 to 15 in the narrow and diffusely paniculate heads: 

 involucre cylindraceous, not at all glandular (4 lines high), of 7 to 9 broadish-linear and obtuse 

 principal bracts and 2 or 3 short ones: akenes comparatively large, fully 2 lines long, chestnut- 

 brown, slightly or at maturity not perceptibly tapering to the summit: pappus dark-fuscous: 

 leaves obovate-spatulate, all in a radical tuft at base of the loosely branching (span to foot high) 

 scapes. 



H. Bolanderi, Gray. Radical leaves sparsely or densely long-hirsute, no other pubescence, 

 scapes and involucre smooth and glabrous. — Proc. Am. Acad. vii. 365, Bot. Calif, i. 440, 

 &Proc. Am. Acad. xix. 68. — Mountains of California, Humboldt Co., Bolander. Near head- 

 waters of the Sacramento, Pringle. Sierra Co., Lemmon. Only Bolander 's specimen has 

 akenes narrowed upward. 



H. Greenei, Gray. Radical leaves villous-hirsute, also canescent-tomentose on both sides 

 with stellular pubescence : scape with peduncles and involucre cinereous-tomentose. — Proc. 

 Am. Acad. xix. 69. — Pine woods of Scott's Mountains, Siskiyou Co., N. California, Greene. 



++ ++ -H- ++ Flowers yellow, 20 to 30 in the oblong heads: akenes fusiform, tapering gradually 

 to a narrow summit, fully as long as the white or whitish and softer pappus : stems scapiform, 

 bearing one or two small leaves toward the base and subulate bracts subtending peduncles 

 or simple branches of the panicle : leaves of radical tuft obovate to spatulate, obtuse, entire or 

 minutely denticulate, contracted into short wing-margined petioles. — § Cliionoracium, Schultz

H. Pringlei, Gray. Strictly scapose, completely destitute of setose hairs and of glands : 

 leaves wholly rosulate, very villous-lanate both sides, obovate (2 or 3 inches long) : scape very 

 slender, a foot or more high, minutely soft-pubescent, as also the involucre, loosely paniculate 

 above, bearing few (4 or 5 lines long) and scattered heads : forming akenes somewhat nar- 

 rowed upward : young pappus soft, bright-white. — Proc. Am. Acad. xix. 69. — S. Arizona, 

 on Santa Eita Mountains, Pringle, Lemmon. Specimens too young. 



H. F6ndleri, Schultz Bip. Subscapose, not rarely one or two leaves toward base of the 

 simple or paniculately branching stem, sparsely setose-hirsute, not at all lanate, not gland- 

 ular or only obscurely so on the peduncles : radical leaves spatulate or broader ; cauline 

 verging to lanceolate, reduced above to linear bracts : heads few and racemiform-paniculate, 

 or more numerous and corymbosely disposed, rather long-pedunculate : involucre half-inch 

 high, of 16 to 24 linear bracts and some short ones, puberulent or glabrate, with or without 

 scattered setose hairs : akenes 2j to fully 3 lines long, tapering from near the base to sum- 

 mit (at maturity the alternate nerves usually thicker than the others), sometimes reddish, at 

 length commonly blackish: pappus copious, soft, sordid- whitish. — Bonplandia, ix. 173;

Var. discolor, Gray, 1. c. Radical leaves (sometimes large, roundish, and over 2 

 inches broad) purple beneath: pappus nearly pure white. — Santa Rita and Huachuca 

 Mountains, S. Arizona, Lemmon, Pringle, the latter distributed as Hieracium erythrospermum, 

 Greene, ined., which is the following. 



Var. Mogollense, Gray, 1. c. Leaves narrower, hardly if at all pnrple-tinged ; 

 bristly hairs disposed to be shorter : peduncles minutely and sparsely glandular-setulose : in- 

 volucre smaller (only 5 lines high) : immature akenes reddish : pappus pure white. — H.
