G. glutinosa, Dusal. Herbaceous nearly or quite to the base ("fruticose," Cav.), a foot 

 or two high : leaves rather large, obovate or spatulate, mo.stlv rounded at summit and with 

 partly clasping (liruad or uarruni^li) l«i,-e, more or less serrate : heads large: involucre half 

 to tbree-lourths inch high, its bracts close, acute or acuminate, with no prolonged sijiiarrose 

 • tips : akenes obscurely if at all bordered at summit : pappus-awns 5 to 8, stout and flattened, 

 sparingly ciliolate-scabrous or nearly smooth. — Mem. Mas. 1. c. -19; DC. Prodr. v. 314;

 as figured Ijy Cavanilles; in Californian specimens varying from obscurely so to smooth.)

* G. robusta, Xitt. Herbaceous to the base, rigid, branching, usually glutinous in the man- 

 ner of G. S(/ua>Tosa, which it resembles in the attenuate-acuminate and si|uarrose spreading 

 or recurved tips to the involucral bracts : leaves more rigid and larger, oblong, varying to 

 lanceolate, rigidly spinulose-serrate or denticulate, or uppermost entire : heads usuallv half- 

 inch high: akenes (at least outer ones) obliquely auriculate or broadly uuidentate at summit: 

 pappus-awns 2 or 3, rarely more. — Trans. Am. Phil. .Soc. 1. c. 314 ; Torr. cSb Gray, 1. l. ; Gray,

" G. nana, Xutt. Rather low and slender, 6 to 30 inches high, the larger plants corjTubosely 

 and freely branched above : leaves thiunisli, lanceolate and linear, or the lower spatulate, 

 entire or spinulose serrate : heads small (a quarter to a third of an inch high) : bracts of 

 the involucre with slender and squarrose soon revolute tips, in the manner of G. squarrosa 

 (which this species represents northwestward): rays 16 to 30: akenes narrow, excisely 

 ■ truncate or bidentate at summit: pappus-awns mostly 2. — Trans. ^Vm. Phil. Soc. 1. c. 314.

* * * Anomalous and obscure species, wholly glabrous : cauline leaves all v-ery small and 

 narrow, almost filiform. 



G. Inimilis Homv. & Arx. Xot glutinous, apparently perennial: stem simple, slender, 7 

 inches high, 2-ceiiliabjus at summit: radical leaves linear, 2 inches long, 2 lines wide at the 

 obtuse obscurely denticulate apex, thence gradually tapering to base; cauline nearly all 



' small and bract-like, all hut lowest half-inch long, not over one third of a line wide, 

 attenuate-acute, involucre half-inch high; bracts lanceolate, acute, largely green, erect, the 

 outer successively shorter : rays rather long : bristles of the pappus apparently 3 or 4, 



slender. Bot. ISeech. 147. — Single specimen known, "California, Beecliey," therefore 



probably from ^Monterey. Very unlike any other.

 and loose branches, with either homochromous or heterochromous flowers, pro- 

 duced in spring. — Trans. Am. Phil. Soc. n. ser. vii. 330; Gray, Proc. Am.
