430 COMPOSITE. Hieracium 



++++++++++ Flowers white or flesh-colored: akenes slender-columnar, hardly narrowed 

 upward, about the length of the bright white soft pappus : stem leafy. (Transition to Crepis.) 



H. carneum, Greene. Wholly glabrous and smooth except below : stem slender, 2 feet or 

 more high, loosely paniculate-branched, glaucescent, its base and the oblong or lanceolate 

 subsessile radical leaves beset with long villous-setiform hairs : cauline leaves narrowly-lance- 

 olate to linear, entire, very smooth, some of the lower sparsely piliferous : heads scattered in 

 the corymbiform or irregular panicle : involucre campanulate, 4 or & lines high, pale, of 

 narrow linear-lanceolate bracts, 15-20-flowered: corollas light rose-color: akenes 2 lines 

 long. — Bot. Gazette, vi. 184; Gray, 1. c. 69. — Mountains of New Mexico, Greene. Also 

 coll. by Bigelow or Wright. Huachuca Mountains, S. Arizona, Lemmon, 



H. Lemmoni, Gray. Villously or hirsutely setose throughout up to the racemiform close 

 thyrsus : stem simple, 2 feet or more high, very leafy : leaves thinnish, lanceolate-oblong, 

 denticulate with callous or glandular teeth ; cauline partly clasping, acute ; lowest oblong- 

 spatulate, 4 to 7 inches long, tapering into winged petioles; those of radical cluster wanting : 

 heads numerous and crowded in the oblong thyrsus, 4 lines high, 12-20-flowered: involucre 

 glabrous or nearly so, not glandular, not longer than the canescently puberulent peduncles ; 

 its principal bracts narrowly linear, greenish-livid, obtuse : corollas short, seemingly white : 

 akenes hardly 2 lines long, slender, obscurely if at all narrowed upward when mature but 

 obviously so when younger : pappus less copious than in the preceding, bright white. — 

 Proc. Am. Acad. xix. 70. — S. Arizona, at Bear Spring, Cave Canon, near Fort Huachuca, 

 Lemmon. A species of Mexican type, of the group lliyrsoidea of Fries. 

 H. absoissum, Less., a Mexican species (with habit of H. Lemmoni, but less leafy), probably 



also including Ii. thyrsoideum, Fries, is said, in Fries, Epicrisis, 150, to come from " Texas ad 



Malpays de la Joyas" (an unrecognized locality), and from "Alabama." 



227. CREPIS, L. (Name used by Pliny for some now unknown plant, 

 from KpTj-n-is, a boot or sandal.) — Chiefly a European genus, of annuals or peren- 

 nials, with soft white pappus and narrow-necked or beaked akenes, some with 

 truncate or merely upwardly attenuate akenes ; the involucre apt to be thickened 

 at base, and leaves to be pinnatifkl. Flowers in all ours yellow. — Torr. & Gray, 

 Fl. ii. 487 ; Benth. & Hook. Gen. ii. 513. 



# Annuals or hardly biennials, sparingly introduced from Europe : akenes beakless or nearly so: 

 bracts of involucre thickening and becoming more or less rigid at base after anthesis. 



C. vfr.ENS, L. A foot or two high, erect or ascending : leaves from dentate to laciniate-pin- 

 natifld, spatulate to lanceolate; cauline with sagittate somewhat clasping base: heads 

 slender-peduncled, small : involucre 3 or 4 lines high : akenes oblong, 10-striate, smooth, 

 slightly and about equally contracted at both ends. — Vill. Fl. Delph. iii. 142. C. polymor- 

 pha, Wallr. ; DC. Prodr. vii. 162, mainly. Malacothrix crepoides, Gray, Pacif. R. Rep. xii. 

 49, & Crepis Cooperi, Gray, Proc. Am. Acad. ix. 214, a small and diffuse somewhat naked- 

 stemmed form, with scattered heads. — At landings and near towns on the Columbia River, 

 Oregon and Washington Terr., probably at first a ballast-weed. (Nat. from Eu.) 



C. tect6rum, L. Usually more slender : leaves, narrow, less or not at all sagittate at base : 

 akenes fusiform, with gradually attenuate summit, upwardly scabrous on the ribs. — A 

 ballast-weed at New York Harbor. In fields at Lansing, Michigan. (Nat. from Eu.) 



C. biennis, L. Generally larger, more pubescent or hirsute, leafy-stemmed : leaves runcinate- 

 pinnatifid, or some of the lower spatulate and barely dentate ; cauline with sagittate-dentate 

 base : involucre 4 to 6 lines high, broadly campanulate, somewhat canescently pubescent and 

 hispidulous: akenes oblong with narrower summit, 13-striate, smooth. — Engl. Bot. t. 149; 

 DC. Prodr. vii. 163 (excl. var. Americana) ; Reichenb. Ic. Fl. Germ. 1. 1439. — Waste grounds, 

 Vermont, Pringle. (Nat. from Eu.) 



# * Perennials, indigenous westward or northward : akenes beakless or short-beaked. 



+- Low or depressed, branched from base, glaucescent and wholly glabrous, bearing numerous 

 clustered and narrow short-peduncled heads: involucre cylindrical, 8-14-flowered, of 8 to 10 

 smooth and narrowly linear obtuse equal bracts, in a single series (unchanged in fruit except by 

 thickened midrib close to the base in C. nana), and 3 or 4 short calyculate ones at base: akenes
