p- 459. 
Capitula heterogamous radiate, ray-florets 1-seriate ligulate 
“neuter.” Involucre cylindrical or urceolate, bracts pauci- (or pluri-) 
seriate imbricate coherent 2 their length or more; apices free acute. 
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-sete variously confluent into a sheath below.— 
iffuse or acaulescent herbs with radical or alternate cauline entire or 
pinnatifid leaves and rather large yellow or orange or purple-rayed 
pedunculate capitula. 
A considerable genus of the Cape.

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, 13-3 in. long, 
margins revolute, obsoletely serrulate. Capitula cylindric-urceolate, 
$ in. long (exclusive of the rays), solitary, on peduncles of 1}-24 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, Ot 
times serrulate-ciliate and with narrowly scarious edges. Ligule © 
the ray-florets (about 15) linear, about } in. long.—Harv. et Sond. Fl.

Capitula heterogamous radiate, ray-florets 1-seriate ligulate neuter. 
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 
margins. Anther-base sagittate. Style-branches narrow-linear rather 
obtuse. Achenes turbinate, pappus of numerous biseriate fimbriate 
or denticulate squamse.—Herbs or shrubs, often thistle-like, with 
alternate (or opposite) setose-dentate, pinnatifid or entire leaves 
usually cottony beneath and rather large solitary or subcorymbose 
yellow capitula.
