174 COMPOSITA (Harv.) [ Pentzia. 
white, very unequal-sided, toothed. DC.l.c.137. Chrysanthemum inca- 
num, Thunb. ! Cap. 693. P. cotuloides, DC. 1. c. 138, fide Sp. ea Drege! 
Var. 8. gracilior; slender, leaves an inch long or more, $ of this length simple, 
3-5 lobed; outer inv. scales keeled, pubescent. 
Var. y. microcephala (Fzl.) ; diffuse or procumbent ; heads on short lateral twigs, 
small, few-flowered. (Hb. Sd., D., Hk.) 
Has. Cape Thunberg! Kochman’s Kloof, Mundt./ Knysna, Dr. Pappe/ Uiten-

Hex Riversberg and Bokkeveld, and on the Zondag and Koega R., Drege/ B., Natal, 
Miss Owen! +. Rhosterkop, Zey.! 854. (Herb, Th., D., Hk.) 
A much branched, rigid little bush, more or less clothed with grey pubescence, 
1-2 f. high, Leaves commonly 4-5 lines long, in B. twice that length at least, the 
lobes 1-2 lines long, blunt. Heads variable in size, 2-4 lines diam. I can find 
nothing whereby to distinguish P. cotuloides from Thunberg’s plant, which agrees 
well with recently collected specimens from all the above localities. DC. states that 
Drege’s “P. virgata,” came from Kl, Namaqualand, bnt no habitat is given in the 
* Documente.” 
8. P. globosa (Less. Syn. 266); unarmed, shrubby, rigid, divaricately 
much branched ; twigs thinly canescent, glabrateupwards ; leavessessile, 
pinnati-partite from the base or near it, the lobes in 3-4 pairs, short, 
linear, obtuse (or mucronate), sub-glabrous ; heads terminal, solitary ; 
inv. scales glabrous, lanceolate, taper-pointed, the inner minutely mem- 
brane tipped; pappus unequal-sided, toothed. DO./.¢. 137.

850,851,853. Roggevelt, A. Wyley! (Herb. D., Sd., Hk.) 
Similar to P. virgata, but readily known by the leaves being pinnatisect from the base, 
or very generally so, and especially by the narrow, long-pointed invol. scales. The 
leaf-l are sometimes very short, under 1 line long. Heads 2-4 lines wide, convex. 
_ 9. P. spinescens (Less. Syn. 266); shrubby, rigid, divaricately much 
branched, the old twigs and peduncles hardening into spines; leaves 
petiolate, at the apex 3-lobed or pinnately 5-lobed, the segments shortly 
linear, obtuse, furrowed beneath, glabrescent ; pedunc. widely spreading, 
short incurved, somewhat racemose. DC.1.c.137. Osteospermum spines- 
cens, Thunb. in Herb. ex pte. 
Has. Cape, Thunberg! (Herb. Thunb.) 
The specimen in Herb. Thunb. has suffered much from insects, and I have not 
examined a flower. It is a more robust plant than P. virgata. The twigs are closely 
a The iny, scales obtuse, with a brown, membranous border. Leaves 2-4 lines 
ng. 
10. P. tortuosa (Fenzl); shrubby, dwarf, much branched, flexuous, 
glabrous (microscopically scaberulous); leaves narrow-cuneate, thickish, 
punctate, shortly and bluntly 3-5 lobed; pedune. naked, slender, one- 
headed, the head at first cernuous, then erect; iny. scales broad, obtuse, 
the outer green at back, the inner membranous, pappus none. Tana- 
cetum tortuosum, DC.! l. c. 133. 
inches high, woody, many times forked. Leaves 3-4 lines long, 14 line wide 
at top, pale. Pedunc. threadlike, 2 inches long. Heads 2 lines across. Corolla 
5-toothed, Pappus none.—I follow Fenzl in referring this to Pentzia, of which genus 
it has the habit, §-toothed corolla, and flat receptacle, but no pappus! at least, none 
developed on the fi. when it first opens. I haye not seen mature flowers.
