380 COMPOSITE (Harv.) | Senecio. 
angle-striate, cobwebby, simple, imbricated with leaves throughout ; 
leaves half-clasping and adnate at base, oblongo-lanceolate, acuminate, 
glabrous above, cobweb-tomentose beneath, distantly callous-denticulate 
or entire, with recurved margins; heads in a much branched, dense, 
thyrsoid-panicle, discoid, about 12-flowered ; pedicels short, scaly, gla- 
brate ; inv. glabrous, calycled, of about 8 broadish, flat scales ; achenes? 
Cacalia tomentosa, Th.! Cap. 625 (non Jacq.) 
Has. Cape, Thunberg! (Herb. Thunb.) 
Stem 1-2 ft. high, thick and strong, but full of pith. Leaves 14-2 inch. long, 4-7 
lines wide, erect, one-nerved, the young ones thinly cobwebbed above, adult quite 
glabrous. Infl. not fully opened, very compound, forming: (in the specimen seen) an 
oblong, close panicle; at a later stage probably more corymbose ; both pedicels, 
bracts and invols. glabrous or nearly so. This is very different from S. oliganthus, 
to which it is referred by DC. ; I describe from Thunberg’s specimens. 
83. S. amabilis (DC.! 1. c. 406); stem herbaceous, diffuse? branches 
terete, scabro-puberulous, long, panicled or corymbose at summit ; leaves 
subdistamt, ear-clasping at base, lyrato-pinnatifid, scabrous above, tomen- 
tose-canescent, and netted beneath, the lobes short, obtuse, in few-pait, 
sharply denticulate, the terminal larger ; corymbs densely several headed, 
ending the longish branches of the panicle ; pedicels very short ; heads 
discoid, 8-10 fl.; inv. glabrous, calycled, of about 8 acuminate scales, 
achenes short, hispidulous ; fl. white or whitish ? 
Has. Langekloof, Drege/ (Herb. D., Sd., Hk.) . 
Branches 2-3 ft. long or more, pale. Leaves 2-24 inches long, the upper lobe 
3-1 inch wide; lateral lobes } inch long, 4 lines wide. Inv. 2-24 lines long, the 
scales pinkish at tip, as are the anthers and style. The habit is that of S. incisus, 
from which the discoid fi. heads, &c. separate it. * 
84. 8. Gerrardi (Harv.); herbaceous, tall, viscoso-puberulous; stem 
. + . 4%; cauline leaves eared at base, petioled, ovate or ovate-oblong, 
midribbed and penninerved, unequally and coarsely repando-dentate, the 
imperfect lobules callous-toothed, on both sides closely scabro-puberu- 
lent; rameal leaves sessile, obovate or oblong, toothed; infl. loosely 
corymbose, many-headed ; heads discoid, homogamous, 15~-20-fl. ; inv. 
scabrous, calycled, of 10-12 linear acuminate scales; lobes of the cor. 
barbellate; achenes terete, striate, glabrous or nearly so. 
Has. Umvote District, Natal, W. 7. Gerrard! 1010. (Herb. D.) 
‘Stems 4-5 ft. high.” Petiole (of the only cauline leaf seen) about 1 inch long, 
1 line wide, with a roundish, dentate lobe at base; lamina 24-5 inches long (pro- 
bably much more), 14 inch wide. Of this plant I have received but a single leaf 
and a branch of the inflorescence; these are quite unlike any species known to me. 
Curiously enough, though the foliage is so very unlike that of S. rhyncholenus, the 
flowers and fruit in both are almost identical. 
85. 8. pandurifolius (Harv.); stem? twigs and peduncles thinly cob- 
webbed; cauline leaves . . 3; rameal leaves panduriform, or with a 
broadly winged petiole amply eared at base, and an ovate, broadbased, 
acute or acuminate limb, calloso-denticulate, penninerved and netted- 
veined, cobwebby becoming glabrate above, cottony-canescent beneath, 
the upper ones smaller, with shorter petioles ; corymbs few-headed, pant 
cled ; inv. calycled, subglabrate, of 8-9 scales; heads discoid, about 
12-fl.; achenes glabrous.
