Pentzia.] COMPOSITE (Harv.) 173 
4. P. Cooperi (Harv.); shrubby, erect, unarmed, the young parts 
cobwebby-floceulent, the adult becoming glabrous; leaves narrow-cu- 
neate, tapering much at base, truncate and sharply 3-toothed or trifid 
at the sumniit, punctate, glabrous ; corymbs compound, many-headed ; 
heads on long or short pedicels, globose ; inv. oblong or ovate-oblong, 
obtuse, the outer herbaceous, inner scarious, glabrous; pappus white, 
rather short, unequal-sided, toothed. 
Has. District of Albert, near the Witberg, and in Basutuland, 7. Cooper/ No, 
628, 711. (Herb. D.) 
1-2 feet high, erect, with erect rodlike branches. Young twigs and leaves hoary 
with cobwebby hairs ; older twigs minutely puberulous. Adult leaves glabrous, 
5-8 lines long, 2 lines wide at the 3-toothed summit. Corymbs 6-20-headed, flat- 
topped. Uppermost leaves often entire, round-topped. 
5. P. quinquefida (Less.! Syn. 266); shrubby, erect, virgate, silky- 
canescent or cinereo-pubescent, unarmed ; leaves cuneate, tapering at 
base into a petiole, truncate at the apex, and 3—5-toothed or lobulate, 
the teeth or Jobes obtuse, closely silky-canescent, the uppermost leaves 
linear, entire; pedunc. one-headed, long or shortish; inv.-scales obtuse, 
the outer strongly keeled, silky. Cotula quinguefida, «h.! Cap. 695.

peduncles long. Penétzia nana, Burch. Cat. 1731. Trav. t. p. 400.

Koegakamma Kloof, Zey.! 852. 8. Ky-Gariep, Burchell. (Herb. Thunb.) 
A foot high, all the young parts silky-canescent. Leaves 5-6 lines long, 2-3 lines 
wide at top, sometimes merely crenate, sometimes deeply toothed or lobed, varying 
in the same plant. Pedunc. 2-6 inches long. I have not seen Burchell’s P. nana, 
but by the characters assigned to it, it can scarcely differ from the plant collected 
by Thunberg and here described. -Drege’s specimen of P. cinerascens (Hb. Sd.) is 
also identical. Except in the cuneate and shortly-lobed leaves this scarcely differs 
from P. spherocephala. 
6. P. spherocephala (DC.! 1. c. 138); shrubby, rigid, branching ; 
branches erect, virgate, thinly cinereo-canescent; leaves petiolate, in 
the upper half pinnati-partite, the lobes linear, obtuse, in 2-3 pairs, 
the upper leaves trifid or entire, closely and thinly canescent ; branches 
ending in a long one-headed peduncle; heads flattish, very many flow- 
ered; inv. scales thinly pubescent or nearly glabrous; oblong, obtuse, 
scarious at margin, the outer keeled ; pappus unequal-sidedy toothed. 
Has. Near the Zwartkey and Fish R., Drege! Uitenhage, Ecklon. Koegakamma

A more robust, less divaricate bush than P. virgata, with much longer flowering 
stems and larger heads. Fl. branches, often a foot or more long, naked for 3-6 inches 
below the head. Leaves 1 inch or more long, the lobes 4-5 lines long; or, in starved 
specimens, of half that size. Heads half an inch or more across: the largest in the 
genus, 
7. P. virgata (Less.! Syn. 266); unarmed, shrubby, rigid, divaricately 
much branched; twigs thinly canescent; leaves petiolate, at the apex 
trifid, or pinnately 5—lobed, the lobes linear, obtuse, with revolute mar- 
gins, more or less canescent ; heads terminal, solitary ; inv. scales nearly 
glabrous, oblong, obtuse, scarious at the margin, the outer keeled ; pappus
