Senecio. | COMPOSITE (Harv.) 371 
linear. Heads sometimes 2-3 on long, simple pedicels ; sometimes 10-12, in a 
branching, very lax corymb. Pedicels 3-4 inches long. Heads 3-3 inch across, 
Very variable in size, but generally recognizable by its leaves, involucre and achenes. 
I suspect that S. afinis and S. inornatus, both unknown to me, are varieties of this 
common plant. Our var. e. looks different, but has scarcely characters sufficient to 
separate it specifically. S. leiocarpus, DC.! of which I have seen Ecklon’s speci- 
mens in the Cape Govt. Herb. seems to me to be founded on a half-starved, narrow- 
leaved form of this species; the specimens, however, are in miserable condition, 
half decayed. . 
53. S. inornatus (DC. 1. c. 385); “herbaceous, quite glabrous; stem 
terete, striate, erect, laxly panicled, sparingly leafy ; leaves lance.-linear, 
subcoriaceous, the lower petiolate, dentato-serrate, upper sessile, quite 
entire; pedicels nude; inv. about 10-12 scaled, shorter than the dise,, 
calycled with small bracteoles; disc 15-fl.; rays 5; achenes glabrous.” 
Has. Betw. Grahamstown and Bothasberg, and betw. Zandplaat and Komga, 
in pastures, Drege. (Unknown to me.) 
Except for the small size of the fi. heads this, by description, does not differ from 
rm Sees var. 6. “ Leaves 3-4 inches long, 3-4 lines wide. Stem 18 inches 
igh. : 
54, §. caudatus (DC. 1. c. 384); glabrous or nearly so; rootstock 
nude; stem herbaceous, erect, angular and furrowed, leafy to the mid- 
dle, either one-headed, or dividing into 3-4 one-headed, nearly nude 
branches ; radical and lowest cauline leaves oblongo-lanceolate or lan- 
ceolate, penninerved, membranous, acute, entire or calloso-denticulate ; 
medial broad-based, clasping, many-striate at base externally, acumi- 
nate ; upper leaves small, tapering into a long, narrow, acute, ciliolate, 
tail-like point; rameal leaves reduced to subulate, attenuate scales; inv. 
of about 20, glabrous, linear-subulate scales, calycled with a few subu- 
late bracteoles of equal length ; rays 12-13, twice as long as the invo- 
lucre ; achenes tapering upwards, glabrous. 
Has. Katriver'sberg, Drege! H. Hutton! (Herb. D., Hk.) 
Stem (in Mr. Hutton’s plant) 2-3 feet high, sharply angular. Lower leaves 6-7 
inches long, 2-2} inches wide; medial 3~4 inches long, 21—3 inches wide; in Drege’s 
specimens, which are very imperfect (Herb. D. Hk.) much narrower, scarcely } inch 
wide. Pedicels 6-16 inches long. Rays 11} inch long. I describe from Mr. Hut- 
ton’s complete and well-preserved specimens, gathered on the Katberg ; and I omit 
all notice of Ecklon’s (Herb. Sd.), because they are quite decayed ; so much so that 
I cannot tell whether they belong to this species or not! 
55. S. macrospermus (DC. 1. c. 385); “ herbaceous, erect, cobweb- 
cotonny, subcanescent ; leaves callous-toothed, elongato-lanceolate, the 
lowest petioled, much attenuate at base” [and externally many-nerved]; 
“ cauline sessile; corymb 6—-7-headed, pedicels long, thick, nude” [rib- 
furrowed]; “inv. sparingly and shortly calycled, at length quite reflexed ; 
recept. smooth ; achenes terete-compressed”’ [rib-striate, scaberu/ous in 
the furrows] “tapering a little at each end.” DC. /.c. 
es per apa an empty Ps with its withered invol., and 
some ripe achenes. The leaves are 10-18 inches long (fide DC.) ; the heads an inch 
in diameter. Achenes 4 lines long, pale. 
56. 8. monticolus (DC. 1.c¢. 384); “ herbaceous, erect, glabrous; stem
