Senecio. | COMPOSIT# (Harv.) 365 
a thyrsoid, many-headed panicle; cauline leaves scattered, linear, erect, 
with recurved margins; heads discoid, many-fl.; invol. calycled with a 
few very slender, filiform bracteoles, of 12-15 linear, scabrous, and pilose 
scales ; achenes minutely puberulous. 
Var. 8, monticolus (DC.); leaves more sparingly pilose ; raceme simple ; achenes 
more thickly downy. : 
Has. Kaffirland, Ecklon! Winterberg, Mrs. F. W. Barber, 416. B, on the Wit- 
berg. 7-8000 ft., Drege. (Herb. Sond. D.) 
Rootstock not woolly. Rad. leaves many, 2-3 inches long, 3-5 lines wide, mostly 
acute. Stem 10-12 inches high. Cauline leaves laxly set, 1-14 inch long, 1 line 
wide. Invol. 5 lines long. Pubescence of the achenes close and short. I have not 
seen var 8, which DC. suggests may prove a distinct species. S. thyrsoideus differs 
more by habit, and the very narrow and lax cauline leaves, than by any more defi- 
me character from S. barbatus. It is also like S. macrocephalus, but has discoid fl.- 
eads, 
36. S, Sandersoni (Hary.); perennial, glandularly pubescent, visci- 
dulous; radical leaves none; stem herbaceous, thick and strong but 
fistular, closely leafy nearly to the summit, simple ; leaves sessile, 
shortly adnate-decurrent at base, oblongo-lanceolate, subacute, spread- 
ing, coarsely and unequally toothed, very scabrid ; heads several, in a 
subsimple, scarcely peduncled raceme, discoid, many-fl.; inv. sparingly 
calycled at base, of about 20 linear, scabrous scales equalling the disc ; 
achenes copiously cano-villous. 
Has. Natal, J. Sanderson! 462. (Herb. D., Hk.) 
Stem 2 ft. high or more, 4-5 lines in diam. below, 2-3 lines thick above, equally 
and closely leafy throughout. Leaves 2-2} inches long, 4-5 lines wide, with broad, 
deflexed ears at base, which are adnate to the stem. Inv. 3 inch long, 4 lines diam. 
Heads with upwards of 100 fl. This has something of the habit of S. barbatus, with 
the inflorescence of S. thyrsoideus ; but differs from both in foliage and pubescence. 
Its stems are very thick and strong for a herbaceous plant. 
37. S. incomptus (DC. 1. c. 386); glabrous ; rhizome ligneous, nude; 
stem herbaceous, rigid, terete, much branched from the base, sub- 
dichotomous ; “ lowest leaves petioled” (DC.); upper sessile, oblong, 
inciso-pinnatifid or coarsely serrate, the lobes or teeth on each side 
3-5-9, short, acute, toothed or entire; infl. subdichotomous ; heads on 
short, rigid pedicels, discoid, 12-20-fl. ; inv. narrow, cylindrical, spar- 
ingly calycled, of 8-10, smooth, flattish, narrow scales; achenes striate, 
cano-puberulous. 
Var. f. serratus; upper leaves serrate, the teeth 7-9 on each side. S. serratus,

Stems 5-8 inches high, much-branched and rigid. Leaves small, 1-1} inch long.

88. S. asperulus (DC.! 1. c. 386); whole plant very scabrous, pu- 
bescent ; rootstock not woolly ; radical and lowest cauline leaves

and more or less petioled, rigid, calloso-denticulate, or serrate, with 
reflexed margins, one-nerved ; stem erect, herbaceous, laxly leafy, few-
