 Receptacle shortly alveolate. Anther-base sagittate. Style -branches 

 linear rather acute. Achenes clothed with long rather rigid and elastic 

 hairs ; pappus 1 -seriate closely investing the corolla-tube, in our spe- 

 cies apparently of oo-setss variously confluent into a sheath below. — 

 Diffuse or acaulescent herbs with radical or alternate cauline entire or 

 pinnatifid leaves and rather large yellow or orange or purple-rayed

1. G". serrulata, DC, Prodr. vi. p. 475. A nearly glabrous 

 dwarf perennial herb with short thick woody root-stock; height 

 3-4 in. Leaves radical numerous, shortly white-tomentose beneath, 

 linear, apiculate, with lanceolate sessile sheathing base, 1-^-3 in. long, 

 margins revolute, obsoletely serrulate. Capitula cylindric- urceolate, 

 ^ in. long (exclusive of the rays), solitary, on peduncles of 1^2^ in. 

 long, falling rather short of the leaves. Involucral bracts connate 

 more than half way, subglabrous ; free portions ovate -lanceolate, 

 acute, numerous, in about 2 rows, somewhat recurved -patent, some- 

 times serrulate-cihate and with narrowly scarious edges. Ligule of 

 the ray-florets (about 15) linear, about J iu. long. — Harv. et Send. Fl.

 Involucre broad, bracts oo-seriate, loosely imbricate, more or less con- 

 nate at base, coarsely setose- or spinulose-ciliate or spinescent. Recep- 

 tacle deeply alveolate, cells sheathing the achenes, often with fimbriate

 obtuse. Achenes turbinate, pappus of numerous biseriate fimbriate 

 or denticulate squamae. — Herbs or shrubs, often thistle-like, with 

 alternate (or opposite) setose- dentate, pinnatifid or entire leaves
