Senecio. | COMPOSIT& (Harv.) 359 
stem, flowering branches, bractec, pedicels and involucres all equally and 
densely clothed with gland-tipped, rigid hairs; inv. of 16-18 narrow, 
acute scales, nearly or quite nude at base, pale ; rays 8-10, revolute, 
yellow ; achenes striate, puberulous. 
Has. Bitterfontyn, Zeyher! (Herb. Sond.) 
Probably branching, panicl corymbose; perhaps 1-1} ft. high. I have only 
seen a small and evidently dwarfed specimen, unbranched, about § inches high, 
bearing 2 fl. heads. The glandular pubescence on the inflorescence, combined with 
the glabrous stem and foliage, seems to me, however, to mark this plant so definitely 
that I venture to found a species on very imperfect data. 
18. §. diffusus (Thunb. ! Cap. 686); annual, diffuse, much-branched, | 
aspero-pubescent, glandular; lower leaves bipinnatisect, the lobes 
multifid, divaricate, narrow linear; upper ear-clasping at base, inciso- 
pinnatifid, with entire or toothed lobes; heads few, on long, more or 
less sealy pedicels; inv. of 12-15, scabrous, linear-acuminate scales, 
calycled with few or several subulate, often ciliate bracteoles ; rays 
several, spreading, scarcely equalling the inv., 4-nerved; achenes striate, 
the striz minutely puberulous. S. chamemelifolius, DC.! 1. ¢. 383. 
Has. Zwartland, Thunberg. Konstapel, Drege! (Herb. Th., Sd.) 
Stems many from the base, decumbent or ascending, 6-8 inches long, branched. 
Leaves 1-1} inch long; the lobes 4 line wide. Rays pale yellow. Thunberg’s 
original specimen so nearly accords with Drege’s that I venture to refer S. chame- 
melifolius, DC. to the older species; the imperfect specimen of it (in Hb. Sd.) which 
alone I have seen, chiefly differs in its less compound leaves and more copious 
calycle-bracts. 
19, S. Paarlensis (DC ! 1. c. 383); annual, erect, much branched, 
aspero-pubescent ; stem weak, angle-furrowed; leaves clasping at base, 
the lower petioled, sub-bipinnatisect, the upper sessile, pinnatisect, the 
lobes 4—5-pair, spreading, narrow-linear, acute, entire or toothed ; infl. 
loosely panicled, the pedicels elongate, nude or 1-2-squamellate ; inv. 
of 12-13 scabrous, linear, acute scales, nearly nude at base or 1-2- 
bracteolate ; rays 8-10, spreading, 4-nerved, as long as the involucre ; 
achenes striate, elongate, tapering upwards, cano-puberulous on the 
striz. 
Has. At the Paarl, Drege / R. Zondereinde, Zey.! 2971 (ex pte.) (Hb Hk., Sd.) 
6 inches to 14-2 feet high, panicled. Leaves 1-1} inch long, the lobes 4-1 line 
wide. Iny. 3-4 lines long ; rays deep or pale yellow, sometimes fulvous when dry, 
A specimen (Hb. Sd.) from Drege seems different, having a glabrous and calycled 
involucre ; but it isin an immature state, and therefore doubtful: Drege’s sp. in Hb. 
Hk. agrees with our plant. 
20. S. puberulus (DC.! 1. c. 380); “herbaceous, erect, sparingly 
branched, nearly all parts roughly pubescent ; branches striate, the 
upper long, 1-headed, nude ; leaves lance-linear, toothed or entire, acute, 
the lower tapering at base, the others sessile ; heads on long pedicels ; 
invol. sparingly calyeulate, 16—20-leaved, glabrescent, scarcely shorter 
than the disc ; dise fl. 30-40, rays about 10; achenes terete, striate, 
minutely pubescent.” DC. 1. ¢.
