stem erect, terete; leaves linear-elongate, acuminate, the radical and 
lower either quite entire or variably runcinate, the lobes strongly re- 
curved, taper-pointed, entire or toothed; upper cauline lvs. sagittate at 
base, stem-clasping, toothed or entire ; heads subcorymbose, on a long,

Has. On the flats near Los Tafelberg ; between Buffelvalei and Kraai rivier ; near 
Gaatje; on the Sneeuweberg ; and by the banks of the Zwartkops R., Drege! Zwart- 
kops R., and near Smalldeel, Ceded Terr., Zey./ Near Grahamstown, P. MacOwan, 
531. (Hb. D., Hk., Sd.) 
Mr. Mac Owan’s specimen is much more luxuriant than any I have seen from 
Drege or Zeyher, and the leaves, besides being runcinate, are toothed on and between 
the lobes ; in the common forms the margin is quite entire betw. the lobes. Leaves 
3-10 in. long, 3-8 1. wide. 
2. S. Ecklonianus (DC. 1. c. 184); perennial, glabrous, not glaucous ; 
stem nearly nude, terete, subsimple or sparingly branched; leaves 
chiefly radical, linear-elongate, either entire, runcinate, or runcinato- 
pinnatifid ; cauline few, sessi/e (not sagittate at base) ; heads few, long- 
pedicelled ; inv. subtomentose at base, the sc. membr.-edged ; achenes

Very close indeed to S. Dregeanus, but not glaucous, of smaller size, and with 
fewer and less clasping cauline leaves. Radical leaves rosulate, 4-6 in.long. Stem 
6-12 in. high, few-headed, =

This has much broader, less tapering and more entire leaves than any of this 
section; the cauline leaves especially more thoroughly amplexicaul, and partly 
adnate. Leaves 4-5 in. long, 1-1} in. wide. 
4, §. nanus (Sond.! in Herb.); perennial, glabrous, nearly stemless ; 
radical leaves runcinate or pinnate-lobed, tapering at base, rosulate; 
heads subsessile among the radical leaves ; iny. se. broad, membr.-edged ; 
achenes tapering upwards, much compressed, longitudinally rib-striate, 
the strie smooth. Compos. Z.n. N.n. H., 114. 10, .&Z.! 
Has. Cape, Ecklon and Zeyher/ (Herb. Sond.) : 
A very dwarf plant, probably from some alpine height. Leaves 4—5 in. long; 
‘mostly runcinate, like those of a Dandelion. Heads several, subsessile on a woody 
crown of root.
