Osteospermum. | COMPOSIT& (Harv.) 443 
Very similar in habit and foliage to O. bidens, but differing in the scabrid upper 
surfaces of the leaves, and the tubercled achenes. 
§ 6. Suputirotia. (Sp. 27-30.) 
27. 0. glandulosum (DC. 1. c. 463) ; “suffruticose, erect, branching, 
scabrous with spreading, short, glandular bristles ; branches filiform, 
leafy, one-headed ; lower leaves? ; rameal lvs. sessile, linear-subulate, 
quite entire ; inv. sc. oblong-lanceolate, acute, membr. edged, dorsally 
subscabrid, equalling the dise ; rays 10.” DC. 1. e. 
Has. Wapperthal, Zederberg, Drege. (Unknown to me.) 
28. 0. scabrum (Thunb.! Cap. 714); shrubby, corymbosely branched, 
rigid ; leaves close-set, erecto-patent, sessile, linear-subulate, mucronate, 
keeled, more or less thickly sprinkled with bristles and hard points, 
the younger ciliate; pedunc. terminal, one-headed, glandularly scaberu- 
lous; inv. sc. lanceolate, acuminate, margined, dorsally scabrous ; rays 
10-12 ; achenes bluntly 3-angled, oblique, slightly incurved, with a 
convex, longitudinally ribbed dorsal region, and a smooth, keeled inner 
face, the terminal areole bent inwards. Xerothamnus Ecklonianus, DC. 
Prodr. 5, p. 311. 
Has. Cape, Thunberg! Amsterdam flat and by the Zwartkops Riv., Uit., Z. & Z.! 
(Herb. Th., D., Hk., Sd.) 
A small, erect shrub, 1 foot or more high, the young twigs scabrous. Leaves 3-1 
in. long, 4-3 1. wide, rigid, sometimes very thickly, sometimes thinly covered with 
hard, sharp points. Pedunc. 2-3 in. long. Rays yellow. Anthers sagittate at 
base, exactly as in other species. Disc cor. deeply 5-fid, scabrous on the tube, its 
style simple, truncate, pencilled at the apex only. 
29. 0. triquetrum (Linn. f. Suppl. 385); suffruticose, suberect or 
diffuse, branching, glabrous; branches slender, leafy to the summit; 
leaves close-set, sessile, linear-subulate, acute, smooth, sharply keeled, 
the keel decurrent as a ridge on the twig, the margins flattish or in- 
curved; pedune, about as long as leaves, one-headed, lateral and ter- 
minal; inv. sc. lanceolate-acuminate, longer than the disc ; achenes 
cylindrical, quite smooth, 
Var. 8. aciphyllum; margin and keel of leaves serrulato-ciliolate. O. aciphyllum, 
DC. l. c. 463. (Herb. Sd.) 
Has. Cape, Thunberg! Zwarteberg near Caledon’s Baths, Zey./ 3061. 8B. at 
Piquetberg, Drege. (Herb. Th., Sd., Hk.) 
The young plant suberect ; the older diffuse or trailing. Leaves 3-1-2} inches 
long, about a line wide, rigid, subdecurrent at the edges, and conspicuously so from 
the keel. Pedunc. 1-2 in. long. Heads few-fi. Zeyher’s specimens have shorter 
leaves than Thunberg’s, but in other respects quite agree. The description in DC. 
1. c. of “* O. aciphyllum” well accords with this species ; but a frustule, in Hb. Sd., 
differs as above indicated. 0. triquetrum, DC., p. 465, is probably our 0. pungens, 
30. 0. subulatum (DC. 1. c. 463); “shrubby, erect ; leaves very 
crowded, sessile, quite entire, linear, subulate-mucronate, with subrevo- 
lute margins, the younger erect, loosely cobwebbed, adult glabrous, re- 
flexed ; pedicels villous, one-headed, rather longer than the leaves; iny. 
sc. linear, acuminate, twice as long as the disc, dorsally hispid ; rays 
12-13, longer than inv. ; achenes unknown.” DC. J. c.
