Senecio. | COMPOSIT (Harv.) 399 
sparingly hispid below, glabrous and fistular above ; leaves lance-linear, 
elongate, glabrous, with subrecurved edges, denticulate, ear-clasping, 
the auricle deeply 2-5-toothed or lobed; corymbs few-headed, pani- 
cled; pedicels long, nearly nude; heads discoid, 80-100-fl.; inv. caly- 
cled with several lanceolate, black-tipped bracteoles, of 16-20 flat, gla- 
brous, taper-pointed scales; achenes puberulous. 
Has, Clanwilliam, Ecklon! Brackfontein, Zey./ (Herb. Sd., Cap.) 
Stem tall, 2-3 feet high (or more ?), but weak and herbaceous. ‘Lvs. 2-3 inches 
long, 2-3 lines wide, conspicuously eared at base, the ear deeply several-toothed ; 
those of the upper leaves occasionally much more developed and pectinate-partite. 
Inv. shorter than the fl., the bracts of calycle broader than common. 
145. S. Skirrhodon (DC. 1. c. 401); “herbaceous? erect, quite gla- 
brous ; stem striate, naked at the apex and bifid, 2-headed ; leaves 
sessile, lanceolate, tapering to both ends, on each side with 10-12 
callous teeth ; pedicels sparingly scaly ; inv. calycled, of 15-18 scales, 
ay equalling the disc ; disc-fl. 100, rays 11-13 ; achenes glabrescent.”

146. S. serrulatus (DC. 1 c. 401); hcsheaiins sparingly branched, 
virgate, glabrous; branches long, striate, nude above ; leaves sessile, 
elongate-linear, serrulate, acute; panicle narrow, racemose ; bracteoles 
of the calycle linear, acuminate, subciliate ; inv. of 12 scales as long as 
the disc; rays 10-12, oblong; disc-fl. 30; achenes glabrous.” DC. 1. c.

“2 ft. high, suffr. at base. Lvs. 21 in. long, 1 line wide. Thyrsus oblong.” DC. 
147. S, ineequidens (DC. 1. c. 401) ; rigidly herbaceous, erect, pani- 
culately branched, nearly glabrous ; stem and branches angle-striate ; 
cauline leaves clasping and often eared at base, linear, acute, with 
revolute margins, some pinnatifid with 2-4 pair of short, spreading 
lobes, some unequally and coarsely toothed, and others denticulate, the 
teeth inflexed ; inf. very lax, subcorymbose, the pedicels very long and 
nearly nude, spreading ; inv. calycled, glabrous, of about 20 scales ; 
disc-fl. 60o~70, rays 10; achenes closely puberulous. 
Has. Cape, Drege. Near the Zwartkops R., Uit., Zeyher! 2963. (Herb. Sd., D.) 
Root fibrous, much-branched ; possibly annual. Stems 1-2 ft. high, much- 
branched, the branches spreading. Leaves 14 in. long, 2-3 1. wide, very variable 
in their toothing or lobes, but always with revolute edges. Of Drege’s plant I have 
only seen a scrap (in Hb. Sd.) which seems the same as Zeyher’s, here described. 
148. S. filifolius (Harv., non Berg.) ; suffruticose, much-branched, 
quite glabrous, the branches slender, terete incurved ; leaves half- 
clasping, the uppermost often eared and toothed at base, filiform, with 
strongly revolute margins, acute, either quite entire or Furnished with a 
few unequal, alternate, spreading, filiform, lateral lobes ; inf. loosely 
panicled, pedicels very long, subcorymbose, angular, sparsely scaly, 
curved ; inv. ecalycled, of 12-13 narrow scales ; disc-fl. 40-50, rays 
6-8, revolute ; achenes hispidulous on the stria. 8S. Linifolius, Th. !
