184 COMPOSIT& (Harv.) [Cenia. 
tufted; stems ascending-erect, simple, pilose, ending in a nude, one- 
headed peduncle; radical and lower leaves petiolate, bipinnati-partite, 
the lobules linear, callous-tipped ; cauline sessile, simply pinnate ; all 
villous, with long, soft hairs; pedunc. elongate, glabrous, somewhat 
fistular under the head; invol. scales numerous, bi-triseriate, oblong, 
r-nerved, glabrous, obtuse, with a hyaline, membranous border; heads 
homogamous, all fi. subsessile, with similar 4-toothed corollas; cor.-tube 
narrowly winged, shortly ear-frilled at base; achenes compressed, wing- 
less. Tanacetum hispidum, DC. /1.¢.133. Matricaria hispida, Fenzl! MSS, 
Has. Witberg, Drege! T. Cooper, 660; Draakensberg, Cooper,1022. (Hb. D., Hk., 8d.) 
Stems 6+12 inches long or more, closely leafy in the lower half, pedunculoid up- 
wards ; the upper leaves shorter, simpler, and laxer, gradually passing into scales. 
Lower and radical leaves, including the petiole, 2-24 inches long; upper 4-3 inch. 
Heads depressed or flat, 5-8 lines diameter. This has the aspect of a Cenia. Its 
evidently winged corolla excludes it from Tanacetum and Matricaria, and brings it 
near C. sericea and C. Thunbergii, from both which it differs in having its flowering 
stems leafy to or beyond the middle. 
Doubtful Species, 
C. villosa (DC. 1. c.79); “ whole plant villous-hispid, erect, branched ; 
leaves sessile, pinnati-partite, the lobes of the lower leaves trifid, of 
the upper entire, oblong-linear, mucronate; branches leafless at top, 1- 
headed, pubescent ; inv. scales membr.-edged, elliptic-oblong, obtuse ; 
achenes very thick, muriculate on the dise.” DC.1. c. 
Has. Cape, Burchell, 6462. 
I have not seen Burchell’s plant, but specimens in Hb. Ecklon (Hb. Sond.), named 
* villosa,” seem to me not to differ materially from C. anthemoides. 
C. stenophylla (C. Koch. Bot. Zeit. 1, 40); “villous; stem branched - 
at base; branches simple, elongate, below set with pinnate leaves, above 
leafless ; inv. scales oblong ; ray-fl. stipitate, in 2-3 rows.” Walp. Rep.

Is this the same as C’. Zeyheri, Fenzl? 
LXXII. CENIA, Commers. 
Heads many-fl., heterogamous; ray-fl. female, 1-2 rows, some shortly 
ligulate or bilabiate, (the outer lip ligulate, the inner much shorter 
3-toothed), some (in C. turbinata) without corolla; rarely all the flowers 
tubular. Disc-fl. compressed, 4-toothed. Recept. convex, naked, crown- 
ing the top-shaped hollow apex of the peduncle. Inv.scales biseriate. <Achenes 
compressed, wingless, but margined, oblong or obovate, without pappus. 
DC. Prodr, 6, 82. 
Small, hairy,annual or perennial plants, with pinnatisect, or bipinnatisect, alternate 
leaves, and terminal, 1-headed, naked peduncles. Distinguished from Cotula by the 
marginal rays (not always present), and specially by the hollow, top shaped apex of 
the peduncle, which is very conspicuous in the fruiting heads: hence th name, from 
xevos, empty or hollow . 
Inv. scales marked with 3-5 nerves: 
Rootannual, Stemsslender, diffusely branchedorsimple (1) turbinata. 
Root perennial. Stems suffruticose, ascending or procumbent ; 
weaves with slenderlobes. Pubescence close-lying, 
.
