1, G. Africana (Gr. in Linn. V. p. 411); stemless or forked; leaves 
crowded at the crown, linear-elongate, acute, tapering much at base, 
entire or denticulate, the younger ones setoso-ciliate ; heads sessile, 
seemingly tufted (from the non-development of internodes); inner 
inv.-scales acuminate, ciliate; all the scales of the pappus bristle-pointed.

Has. Karroo, near Beaufort, Zeyher! (Herb. Sond.) 
A minute, scarcely branched plant, 1-3 inches diameter ; the leaves 1-2 inches — 
long, 1 line wide. Several crowded, but not truly fascicled heads in the forks, or 
on the sides of scarcely developed branches. Recept. densely clothed with setaceous 
fimbrils. Disc-fl. with narrow-lanceolate, externally scabrous, erect lobes, and strong 
marginal nerves. Pappus of 8-16 scales, all of them bristle-pointed. Dwarfer than 
G. passerinoides, which it much resembles, but has a different pappus. 
2. G. passerinoides (Harv.) ; stem shrubby, very dwarf, multifid at 
the crown, the branches very short, tufted ; leaves from a dilated, am- 
plexicaul base linear, very long, one-nerved beneath, punctate, glabrous 
or sparsely hispid ; heads terminal or lateral, sessile, ovate, subtended 
by leaves; inner iny.-scales acuminate, ciliate; outer pappus of oblong, 
blunt, inner of bristle-pointed scales. Relhania passerinoides, L’ Her.

§ Zeyher. Zululand, Gerrard, 1024. (Herb. Hk., D., Sd.) 
Root thick and woody. Stem shortly multifid, the crowded branches 1-2 inches 
long. Leaves 1-2-2} inches long, 1 line wide, flat or revolute, thickish, subacute. 
Rays taper-pointed, long. Recept. bluntly conical, thickly clothed with bristle- 
shaped fimbrils. Outer pappus of 5 or 6 oblong, blunt, nerveless scales; inner of as 
many nerved, aristate scales. Style-branches in the disc-fl, deeply divided, the arms 
exserted, linear, flattened. 
3. G. protensa (Harv.) ; suffruticose, glabrous ; stem depressed, sub- 
trichotomous ; leaves linear, tapering to each end ; heads axillary, ses- 
sile, solitary ; recept. densely clothed with long, linear-subulate, flat 
fimbrils ; pappus of 10-12 scales, the 5-6 inner aristate, the outer 
obtuse or mucronate.

Stem woody at base, rigid, flexuous, forked or zig-zag, almost prostrate, a foot 
or more in length. Leaves 3-4 inches long, 1-2 lines wide in the middle, thickish 
in substance, with subinvolute margins, one-nerved, dotted, glabrous, the lower 
scattered, the upper in tufts at the ends of the branches. Heads sessile in the forks 
of the stem, a few of the outer invol.-scales with leafy points ; the next broadly
