mucronate, callous-denticulate, midribbed and penninerved; upper stem- 
clasping, oblong or lanceolate, much smaller; partial corymbs densely

Stem woolly at the very base only, 2—3 ft. high, leafy for 6-12 inches below, ending 
in a much-branched inflorescence. Leaves 4-6 inches long, 2-3 inches wide. Upper 
leaves very erect, narrower, much smaller and ear-clasping. Inv, 3 lines long, 1-14 
wide. Habit of a few-flowered Othonna. 
80. S. venosus (Harv.); glabrous; stem erect, ribstriate, leafy to the 
base of the diffusely branched corymb (lower portion unknown); lower 
leaves . . . .; cauline leaves cordate at base and stem-clasping, lanceo- 
late, acuminate, rigidly coriaceous, thick, ciliato-denticulate, glaucescent, 
conspicuously veiny on both surfaces, on the lower with very prominent, 
oblique, anastomosing veins and veinlets, many-veined at base; partial 
corymbs few-headed, pedicels short ; heads 10-fl., discoid; inv. nude 
at base, funnel-shaped, of 5-6 oblong, obtuse, glabrous scales; achenes 
glabrous. = 
Has. Magalisberg, Oct., Zey./ 936. (Herb. Sond.) 
Apparently a tall plant, with the habit of S. ¢satideus, but leafy throughout, with 
close-placed, strongly and coarsely veiny, very rigid leaves. I have only seen a 
single specimen, about 14 inches long, being merely the flowering top of the stem, 
or of a branch: its leaves are 2-3 inches long, 4~? inch wide at base, very acute. 
Until the lower part of the stem shall be seen the characters cannot be fully given.

81. S. picridifolins (DC.! 1. c. 386); perennial ; stem herbaceous, 
weak, erect, sparingly branched, leafy, scabro-pubescent ; cauline leaves 
membranous, ear-clasping and tapering much at base, oblongo-lanceo- 
late, acuminate, coarsely and unequally toothed, scabrous above, paler 
and more or less glabrous beneath; fl. branches nude and peduneuloid 
at the apex, mostly one-headed, very scabrid ; heads discoid, 80-100 
fl.; inv. calycled, of many linear-acuminate, scabrous scales, achenes 
compressed, rib-striate, minutely scabrid.

Stem 2-3 ft. or more high, fistular upwards, supporting itself among bushes (/) 
but scarcely climbing. Leaves scattered, tapering at base into an imperfect petiole, 
the lower ones 2-3 inches long, 1 inch wide. Upper leaves sessile, broad-based, 
often deeply incised, with larger ears at base. Peduncles mostly 1-headed, rarely 
branched. Burke § Zeyher’s specimens from Magalisberg and Mooje R. seem to 
have grown in drier and more exposed places than those of Natal, being dwarfer, 
more erect, with more rigid foliage, &c. The natural affinities of this sp. are to me. 
very doubtful.
