Pteronia. | COMPOSITA (Harv.) 95 
A small scrubby shrublet. The leaves on the younger branches and twigs are 
3-4 lines long, and 1-2 lines wide ; those on the older branches, which spring from 
oo a old leaf-scars, are often fascicled, and linear or linear-spathulate, with or 
without cilia. 
7. C. tridentata (DC. 1. c. 354); shrubby, glabrous or nearly so; 
leaves thickish, linear, 3-lobed or trifid, the upper ones sometimes linear, 
entire or with one lateral lobe ; heads shortly pedunculate ; iny. scales 
linear-lanceolate, with scarious edges. 
Has. Zwarteberg, and near Kendo, Drege! (Herb. Hk., Sd.) 
A foot or so in height, erect, with rod-like branches. Leaves 3-6 lines long, the 
lobes 4 line wide, either opposite each other or alternating, or one or both abreast, 
Heads nearly as in C. Coma aurea, 
8. C. pinnatifida (DC. 1. c. 354); “shrubby, glabrous; leaves sessile, 
oblong-linear, thickish, pinnatifid, lobes on each side 2~3, entire, obtuse, 
the margins subrevolute ; heads peduncled.” DC. 
Has. Zwarteberg, Drege. 
“ Stem 2 feet high, simple, shortly panicled at the apex. Inv. purplish. FI. pale- 
yellow,” DC.— Unknown to us. 
Sub-genus 2, HeTeropsis. Cor. campanulate, with a slender tube and erect lobes. 
Style shortly bifid. Sete of pappus flexuous, taper-pointed. A tall herb, with simple 
stem, ending in a corymbose injlorescence. Leaves decurrent in narrow wings along the 
stem. 
9. C. decurrens (DC. 1. c. 354); stem angular, herbaceous, -sub- 
simple, thinly pilose ; leaves alternate, sub-distant, elongate, roughly 
hispid, inciso-pinnatifid, decurrent at base, the lateral lobes alternate, 
short, toothlike ; corymb panicled, fastigiate, the subdivisions dense ; 
invol. scales scabrous. 
Var. 8, pterocaula ; lower leaves lyrate, the lateral lobes short and blunt, the 
upper lanceolate. C. pterocaula, DC, l. c. 
Has. Witberg, at the foot of the mountains, in upland valleys and on flats, 4500- 
5000 ft., Drege/ Var. 8, Leeuwenspruit, between Kraai River and the Witberg, 
4500 ft., Drege! (Herb. D., Hk., Sd.) 
Stems 2 ft. or more high, 2—3 lines in diameter ; the leaves 1-2 inches apart, 2-4 
inches long, 2-4 lines wide, the lobes nearly 3 in. apart and 1-2 lineslong. Flowering 
branches corymbose, each division corymbulose, 4-6-headed. Heads 60-80-flowd. 
Achenes minutely pubescent. Var. 8, from nearly the same locality as a, differs 
so slightly that I cannot keep it specifically apart. Of it, however, I have only seen 
an imperfect specimen. Drege’s specimens of var. a. vary in the shape of the leaves. 
XXIV. PTERONIA, L. 
Heads discoid, homogamous, many-fl., rarely 3-1-flowered. Recept. 
honeycombed, the margins of the cells either short or fringed. Jnvol. 
imbricated in many rows. Achenes compressed or top-shaped, glabrous 
or villous, rarely shortly-tapering at the summit. Pappus in many rows, 
bristle-shaped, bristles thickish, closely barbed, often concrete at base. 
DC. Prodr. 5, p. 356. 
A large and natural genus of S. African small, dry, or glutinous shrubs. Leaves 
opposite or rarely alternate, mostly entire, glabrous or hairy, often ciliate. Heads 
terminal, solitary or corymbose. Inyol. scales scarious, often shining. Flowers 
yellow, rarely purple.-—Name, from rrepoy, a wing.
