392 COMPOSITA (Harv.) [ Senecio. 
glabrous inv. scales, if this be constant, I cannot distinguish it from S. lineatus, 
which often has basal leaf-lobes. 
121. S. penninervius (DC. 1. c. 395); “stem suffruticose, erect, cinereo- 
puberulous, somewhat naked upwards ; leaves sessile, lyrate, having at 
base on each side 3-4 lanceolate lobules, the terminal lobe (or principal 
lamina) lanceolate, serrate, penninerved and cinereo-pubescent beneath, 
glabrous, with impressed veins above; corymb compound, many-headed ; 
heads 25—30-f1.; inv. calycled, glabrous, half as long as the disc-fl. ; 
rays twice as long as the involucre.” D0. l. ¢.

Unknown to me. It is said greatly to resemble 8S. triplinervius, but to differ in 
the more distant leaf-lobes, here and there toothed, in the terminal lobe which is 
serrate nearly throughout, and in the more numerous heads, Both are probably 
mere vars. of S. lineatus. 
§ 7. Leprotoni. (Sp. 122-138.) 
122. §. umbellatus (Linn.); glabrous or nearly so; stem suffruticose 
at base, erect, branching, striate; leaves linear, elongate, with strongly 
revolute margins, acute, quite entire, or here and there sparsely and 
irregularly toothed or pinnati-lobed, the teeth or lobes subulate, widely 
spreading ; corymb laxly few-headed, the pedicels long and nearly nude; 
heads many-fl., radiate, the ray purple; inv. amply calycled, with many 
subulate bracteoles, of about 20 glabrous, narrow scales; achenes stri- 
ate, puberulous. DC. l.c. 408. S. linifolius, Drege! ex pte. S. tenuilobus, 
DC. t. c. 398. 
Var. 8. latiusculus; leaves shorter, broader (1-14 inch long, 14-2 lines wide), 
with less reflexed margins, denticulate. 
Has. Cape Flats, Wallich! W. H.H.! Kamiesberg, Drege! 8. Betw. Vanstaa- 
‘densberg and Bethelsdorp, Drege! (Herb. D., Hk., Sd.) 
Stem 1-2 feet high, forming a much-branched suffrutex, the lower parts ligneous, 
the upper herbaceous. Leaves 2-3 inches long, $-1 line wide, more usually quite 
entire and simple; but varying on the same branch to toothed or lobed. Infl. like 
that of S. grandiflorus ; pedicels 2-3 inches long or more. Rays purple, but in Her- 
baria often faded to an uncertain, dingy whitish or buff-colour: such specimens have 
been distributed as “S. linifolius” (linoides? DC.) by Drege (Hb. Sd.). Eeklon’s 
specimens (Hb. Sd.) are in a wretched condition, quite scabrous, and do not seem to 
belong to our plant. 4S. tenuilobus, DC., unless it have yellow rays, which I cannot 
determine from the imperfect specimens seen (Herb. D., Sd., Hk.), differs in no re- 
spect from ordinary S. umbellatus. 
123. S. grandiflorus (Berg. Cap. 280); herbaceous, perennial; stem 
tall, strong, virgate, striate, nearly glabrous, leafy for the greater part, 
nude and panicled at the summit; cauline leaves sessile, half-clasping, 
pinnati-partite, the lobes on each side several, linear, acuminate, entire 
or toothed, with subrecurved margins, the lowest short or toothlike, all 
sparsely pilose or sub-glabrous; panicle laxly corymbose, the partial 
corymbs 3~5-headed, the pedicels long and nude; heads many-fl., radiate, 
the rays purple, disc yellow; inv. amply calycled with many subulate, 
spreading bracteoles, of 18-20 narrow, glabrous scales; achenes black, 
striate, minutely puberulous in the furrows. Less. Syn. 301. DC./ 1. ¢.
