2. A. elata (Sond. in Linn. vol. 23, p. 67); stem tall, tapering up- 
-wards, very much branched, the branches lateral, spreading, filiform, 
simple or ramulous ; leaves linear, sessile, acute, glabrous and smooth 
above, tomentose with revolute margins beneath ; heads terminal and 
lateral-secund in the axils of the upper leaves ; invol. scales bristle- 
pointed, syuarrose; achenes pilose ; pappus with interposed scales. 
Has. Magalisberg, Burke § Zeyher! Zey.! 911. Basutu Land, 735, and Albert, 
No. 1754, T. Cooper! (Herb. Hk., D., Sd.) : 
Stems 2-3 feet high, rigid, ligneous, terete, straight and tapering to a fine point; 
-branches lateral, spreading or recurved, filiform, in large specimens emitting lateral, 
spreading twigs; young parts cobwebbed or woolly, old glabrate and glossy. Leaves 
‘ about 1 inch long, 4 line wide. Heads sometimes ending the branches, but more 
commonly subsessile, or on short, axillary twigs in the axils of the upper leaves, 
and then secund. Achenes exactly like those of A. phylicwfolia. 
8. A. angustissima (DC.! 1. c. 277); stem slendet, erect, slightly 
branched, the branches erect ; leaves narrow-linear, acute, sessile, quite 
glabrous and smooth above, tomentose below with revolute margins ; 
inv. scales setaceous, erect ; ovaries slender, elongate, glabrous at base; 
pappus with interposed scales, the bristles very caducous. 
Has. On the Witberg, 6-7000 f., Drege! (Herb. D., Hk.) 
4-6 inches high, probably tufted. Leaves 1-14 inch long, 4 line diameter, rigid, 
erecto-patent. Heads ending the branches, sub-peduncled, with a few scales on the 
—— smaller than in other species, the inv. scales very narrow and bristle- 
pointed. 
4, A. Gerrardi (Harv.); stem ascending-erect, sparingly branched, 
robust; branches erect, closely leafy to the summit, pubescent; leaves 
sessile, not decurrent, linear, with recurved points and revolute margins, 
rough with glandular bristles on the outer surface, tomentose beneath ; 
pappus with interposed scales. 
Has. Dry plains in Zululand, W. 7. Gerrard! 1029. (Herb. D.) 
Stem 1-2 ft. high, much stronger and more densely leafy than in A. Capensis, very 
rough with glandular hairs. The leaves are uniformly linear, 1-1} inch long, 4 
line wide, not in the least decurrent at base. Heads 3 inch long, and wide ; inv. 
scales bristle-pointed. Flowers blue. Achenes hispidulous at base. Quite unlike 
A, sessilifolia, DC. 
5. A. heterophylla (Less.! Syn. 366); stem ascending-erect, sparingly 
branched, branches cobwebbed, simple or ramulous ; lower leaves ob- 
long, upper linear-subulate, pungent, with revolute margins, strongly 
decurrent at base, rough with glandular bristles outside ; pappus with 
interposed scales. DC.1.¢c.277. Aster heterophyllus, Th.! Cap. 688.

Undistinguishable from A. Capensis by any character except that of the pappus! 
_ the lower leaves are sometimes as narrow as the upper. Drege’s specimens (in Herb. 
D., Hk.) of A. sessilifolia, DC. have the leaves certainly decurrent, and a tuft 
of hairs at base of achene, and do not at all differ from weakly specimens of A. 
heterophylla, f
