362 COMPOSIT (Harv.) [Senecio. 
corymb laxly several-headed, the pedicels long and scaly ; heads radiate, 
30-50-fl., the dise yellow, rays purple; inv. nearly nude at base, of 
12-13 narrow, keeled, scabrous scales; achenes tapering, striate, puberu- 
lous. S. elegans, Th.! Cap. 785, Less. Syn. 391. (ewel. syn. Linn. ) 
C.! 1.¢. 408. S. myrrhifolius, Th. ! Cap. 685. S. Volkamert, Sch. Bip. 
Has. Sandy ground near Capetown and in the Western Districts, common. 
(Herb. Th., D., Hk., Sd.) ? 
A smaller and more slender plant than S. elegans, from which it is at once dis- 
tinguished by its very dissimilar involucres. Stems 3-18 inches high, weak. 
Thunberg, both in his Herb. and Flora, confounds with it S. elegans and a hispidu- 
lous form of 8S. littoreus: and gives the name myrrhifolius to specimens with more 
divided leaves. Of the synonyms at my disposal, I adopt arenarius, as being most 
appropriate. 
27. S. cakilefolins (DC. 1. c. 408); “annual, herbaceous, glabrous, 
erect; leaves sessile, ear-clasping, pinnatipartite, the lobes obtuse, the 
margin here and there revolute, fleshy ; corymb subfastigiate, branched, 
pedicels nearly nude; iny. 1-seriate, not calycled, of 20-24 linear 
scales.” DC. 1. c. 
Has. Silverfontein, Drege. (Unknown to me.) 
Allied to S. arenarius, from which it differs by its glabrous surface and larger 
fl. heads. P 
§ 2. Smnvost. (Sp. 28-49.) 
28. S. macrocephalus (DC.! 1. c. 407); perennial, glandular and 
more or less pilose with long, soft, jointed hairs; radical and lower 
leaves obovate-oblong, obtuse, narrowed to the base, but not petioled, 
irregularly toothed or repand ; stem herbaceous, ascending, leafy, sub- 
simple, racemose at the summit ; cauline leaves clasping, oblong, sub- 
dentate, obtuse or acute; heads in a simple or slightly branched raceme 
or thyrsus, pedicels not twice as long as the head ; inv. sparingly caly- 
cled with a very few long, narrow bracteoles, of 18-20 narrow pilose 
or hirsute scales; heads radiate, 60-80-fl., disc and ray purple; achenes 
striate, pubescent. 
8. hirsutissimus ; upper part of stem, pedicels and involucres, shaggy with very 
copious, long, soft, jointed hairs. (Herb. D.)

(Herb. D., Hk., Sd.) 
Very near S, concolor, from which it is chiefly known by its simpler and more leafy 
stems ; racemose inflorescence, sessile (or very obscurely petioled) lower leaves, and 
somewhat larger fi. heads. Var. 8. is remarkable for its excessive indument, re- 
sembling that of some of the Andean Culcitia. It only differs from S. thyrsoideus 
by its rayed fl. heads, 
29. S. concolor (DC.! 1. c. 407); perennial, glandular, and more or 
less copiously clothed with soft, jointed hairs; radical and lower leaves 
petioled, oblong, obtuse, either toothed, incised or lyrato-pinnatifid, with 
short, blunt lobes; stem herbaceous, ascending, weak, leafy below, nude 
and subdichotomous above; cauline leaves ear-clasping, oblong or linear, 
toothed or subentire; corymbs laxly few-headed, the pedicels long; Inv. 
nearly nude at base, of 15-20 narrow, pilose scales ; heads radiate, 
50-f1., dise and ray purple ; achenes striate, puberulous.
