COMPOSITiE. 463 



alous branches clothed with small scattered ovate-oblong entire sessile 

 leaves: involucres short, only % in. high, much exceeded by the salmon- 

 colored tubular corollas: achenes glandular-hirsute. — At middle eleva- 

 tions on Mt. Shasta. A most anomalous species; the probable type of a 

 genus. 



* * Heads radiate and shoiry. 



4. A. Sonnei, Greene, Pittonia, iii. 104 (1896). Two feet high, leafy 

 at base, the upper 2 or 3 pairs of leaves much reduced and remote; the 

 lower and radical ones with broadly lanceolate evenly and saliently 

 dentate blade 3 — 5 in. long, on a strongly villous-lanate petiole of 1 — 3 

 in.; herbage loosely and scantily villous; heads 3 — 7, pedunculate: invo- 

 lucre campanulate, % inch high or more; the linear-lanceolate bracts 

 loosely hirsute: rays (occasionally wanting) numerous, golden-yellow: 

 disk-corollas rather narrowly funnelform, the tube and throat pilose: 

 achenes glabrous below, distinctly hirsute above the middle: pappus 

 dull - white, barbellate. — Mountain slopes along the Truckee River, 

 Sunrte. 



5. A. cordifolia, Hook. Fl. i. 331 (1833). Usually 1—2 ft. high, or 

 smaller at alpine elevations, the stems mostly hirsute and peduncles 

 villous: leaves rather few, the radical and lower cauline ovate or ovate- 

 cordate, coarsely dentate, ample and on long petioles, the upper cauline 

 small, sessile: head commonly solitary; involucre % in. high, pubescent 

 or villous: rays 1 in. long: achenes more or less hirsute. — Eastern slope 

 of the Sierra, and not common. 



6. A. Nevadensis, Gray, Proc. Aju. Acad. xix. 55 (1883). Rather 

 smaller than the last, of the same habit and general aspect, but leaves 

 more rounded and ol)tuse, not cordate, but oval or oblong rather, usually 

 entire: involucre J2 iii- high: achenes minutely pubescent and glabrate. 

 — From Lassen's Peak to the heights above Donner Lake, ilrs. Austin, 

 Mr. Sonne. 



7. A. latifolia. Bong. Sitch. 147 (1832). More slender, the cauline 

 leaves ovate, obtuse, serrate-toothed, closely sessile by a broad base: 

 beads several, ?:£ in. high: achenes glabrous; pappus almost subplumose. 

 — In the Truckee Valley and northwards. 



8. A. longifolia, D. O. Eaton, Bot. King Exp. 186 (1871). Stems 

 tufted and tall, 2 — 3 ft. high; herbage puberulent: cauline leaves 

 strongly developed, elongated-lanceolate, tapering to both ends, dentic- 

 ulate, 3 — 6 in. long, the lower with connate-sheathing base: heads rather 

 numerous, small and corymbose : achenes minutely glandular, not
