A foot or 18 inches high, corymbosely much branched; branches erect. Leaves 
3-4 lines long imbricating in alternate pairs, erect with recurved, callous points. 
Heads not many flowered, the invol. pale. Paleze subulate, shorter than the flowers. 
Lessing omits to mention that the leaves are opposite. Thunberg’s specimens entirely 
agree with those from Dr. Thom. 
8. R. sedifolia (Harv.); glabrous ; leaves alternate, crowded, linear, 
thick, obtuse, impress-dotted, erect, the youngest subpubescent; heads 
solitary (or few) at the ends of the branches, oblong, sessile; inv. scales 
narrow-linear, the outer obtuse, the inner acuminate ; palez slender, 
rigid, as long as the flowers. clopes sedifolia, DC. l. c. 288. 
Has. Zeederberg, Drege! (Herb. Hk., Sd.) 
A small, rigid, nearly glabrous shrublet. Leaves 3-4 lines long, straight and 
erect, not curved-tipped. Achenes slender, glabrous. Pappus 2-5 parted. Heads 
few flowered. 
9. R. centauroides (DC. 1. c. 288); “branches irregularly forked, 
the younger hairy, the adult glabrous; leaves alternate, scattered, close- 
together, subimbricate, carnoso-subtrigonous, acute ; heads solitary, ses- 
sile, discoid? ; inner inv. scales scarious and lacerate at the apices.”

10. R. quinquenervis (Th.! Cap. 641) ; twigs hairy ; leaves lanceo-

(Herb. Th., D., Hk., Sd.) 
A larger and stronger bush than R. trinervis, from which it is known by its villous 
and hirsute green pubescence ; never albo-tomentose. The young plants are densely 
villous all over, the older more or less glabrate. In Herbaria it is often marked 
“* subpungens.” It varies with broader or narrower leaves, the narrow-leaved variety 
being most frequently mistaken for R. pungens. 
11. R. trinervis (Th.! Cap.641) ; twigs albo-tomentose ; leaves lance- 
subulate or lanceolate, concave and tomentose within, convex, cobwebby 
(becoming glabrate) and 3—5-nerved beneath, pungent, straight, spread- 
ing ; heads solitary. terminal, sessile ; inv. scales oblong, obtuse or sub- 
obtuse. LEclopes parallelinervis, Less. Syn. 380. DC. l. c. p. 289.
