Has. Dutoitskloof, Drege! (Herb. D., Hk., Sd.) 
Very near O. quinguedentata, but with thinner, less cuneate, more taper-pointed 
leaves, strongly decurrent at base, with usually more teeth. Drege's specimens of 
0. grandidentata and pluridentata are from the same locality, and by me undistin- 
guishable ; the number of teeth is a most uncertain character. 
18. 0. membranifolia (DC. ! 1. c. 476); suffruticose, erect, glabrous; 
stem simple, terete, leafy, ending in a corymbose, leafy panicle; leaves 
subpetiolate, broadly elliptical or obovate, subacute or obtuse, mem- 
branous, midribbed and penninerved, entire or remotely toothed above 
the middle ; floral leaves (on the panicle) ovate or roundish, cucullate, 
concave ; corymb laxly branched, its subdivisions few-headed, pedicels 
long ; inv. sc. 8, oval, acute, connate below ; ray achenes glabrous. 
Has. Zwartkops R., Uit., #. ¢ Z.! Zey. 3043. (Herb. D., Sd., Hk.) 
In habit and foliage very like O. amplexicaulis ; but the leaves are not amplexi- 
caul, their toothing (when present) is different, their substance thinner ; the corymb 
is much less compound, more leafy, with fewer and larger heads, and the achenes 
are glabrous. 
19, 0. amplexicaulis (Th.! Cap. 718); suffruticose, erect, glabrous, 
subsimple ; stem leafy, terete, ending in a much-branched, corymbose 
panicle ; leaves eared and clasping at base, sessile or adnate-subdecur- 
rent, broadly obovate or obovate-oblong, or oblong, mucronate, coria- 
ceous, penninerved, entire or denticulate; corymb level-topped, very 
many-headed, pedicels long, slender; inv. sc. 8, oblong; achenes silky- 
villous. 
Var. a. integrifolia; leaves entire or subentire. O. amplexicaulis, and O. sene- 
cionea, DC. I. c. 475. 
Var. 8. denticulata; leaves denticulate. O. denticuluta, Ait. Kew. 3, p. 276. 
Bot. Mag. t. 1979. DC.! l.c. 475. Also O. rigida, DC.! I. c. 476. 
Var. y.? Dregeana; leaves subdecurrent, entire. O. Dregeana, DC. l. c. 475.

R., Zey.! 3044. (Herb. Th., D., +9 Bd.) 
Stem robust, 3-4 ft. high or more, leafy to the corymb. Lower leaves 6-8 inches 
long, 2-4 in. wide; upper gradually smaller. Except in the entire or denticulate 
leaves this species varies little. I have not seen DC.’s O, Dregeana, which I refer 
here, by description, and because it is stated to grow along with 0. amplexicaulis, 
DC., by the river side, at the Paarl. 
20. 0. umbelliformis (DC. ! 1. c. 474); herbaceous (1), erect, gla- 
brous ; stem simple or divided at base, leafy below, pedunculoid and 
umbellato-corymbose above; leaves obovate, obtuse, cuneate and taper- 
ing much at base, either sharply many-toothed or subentire, thinly 
coriaceous, midribbed and penninerved, the lowermost imperfectly 
petioled, the uppermost ear-clasping ; pedicels long, subequal ; inv. sc. 
7-8; achenes villous. 
Has. Berg River, Drege! Cape, FE. § Z./ (Herb. Sd.) 
Leafy portion of stem 3-4 inches long; pedunc. 6-8 inches, 5-6-headed. Leaves 
13-2 in. long, 4-1 in. wide. Drege’s specimens are immature ; but Ecklon’s have 
ripe achenes. The root seems to be either thick or tuberous, judging from the 
stem-base of Eeklon’s specimens.
