the old parts denuded and cicatricised. ‘Leaves 4 lines to 1 inch long, 2 lines to 4 
inch wide, very rigid and thick, but not fleshy. Pedunc. 1-24 inches long, from 
the upper axils, or along the stem. Var. 8. differs solely by its rather smaller, very 
obtuse leaves ; but the point in the normal form varies greatly, and Drege’s specimen 
from Mierenjesfontein completely unites the two forms. 
26. E, sulcatus (Harv.) ; glabrous; leaves sessile, closely imbricate, 
erect or spreading, oblong, obtuse or subacute, rigid, thick, flattish, 
faintly 3-nerved above, with a medial impressed line or furrow beneath, 
cartilagineo-ciliolate; pedicels lateral, short; inv. sc. about 5, broadly 
oblong, obtuse, 3—4-nerved, subconnate at base ; rays 2-3, short; recept. 
convex, honey-combed ; ovaries hairy, achenes woolly. Othonna sulcata, 
Thunb.! Cap. p. 719. 
Var. 8. densifolius (Sd.); more slender ; leaves secwved at the point, ovate-oblong, 
acute, with a fainter medial line beneath. Z. densifolius, Sond. MSS. £. ciliatus

A rigid, more or less robust shrub, with the aspect of Z. lateriflorus, from which 
it is at once known by its elegantly ciliolate leaves. Leaves 6-7 1. long, 3 1. wide ; 
in 8. 4-61, long 2 1. wide. Pedicels uncial. Heads few-flowered.

E, subsessilis (Sch. Bip. Bot. Zeit. xxviii. 51); “shrubby, branching, 
glabrous; leaves undivided, obovate-oblong, obtuse, about 4 lines long, 
2 1. wide, imbricate, flat, sessile, fleshy, nearly nerveless; heads at the 
ends of the branches, subsessile; inv. sc. about 5, obtuse; rays 33 
achenes villous.” Walp. Rep. 6. p. 272. 
If not £. lateriflorus 8. imbricatus, this must come very near it. 
CXIX. RUCKERIA, DC. 
Heads many-fl., hetero-moneecious; ray fl. ligulate, female; disc-fl. 
5-toothed, mostly abortive (not strictly “male”). Inv. uniseriate, the 
scales more or less concrete at base. ecept. subconvex, areolate. Style 
of the disc-fl. branched (!), its arms truncate, hispid at the apex. Ray- 
achenes oblong, terete; those of the dise slender, abortive, velvetty. 
Pappus of all the flowers in many rows, similar, caducous, the bristles 
exceedingly slender, slightly nodulose, jointed, smooth, at length aggre- 
gated in copious woolly tufts. DC. Prodr. 6. 483. 
8. African suffrutices or herbs, with the aspect of Zuryops. Stems leafy at base, 
ending in long, nude, one-headed peduncles. Leaves pinnate-partite, with linear 
lobes. Flowers yellow. Name in honour of J. F. Rucker, a collector of Cape plants. 
I have only had the opportunity of examining the gen. char. in R. tagetoides, and in 
it, owing to the state of the specimens, very imperfectly: in it I find the disc-styles 
ag — “undivided”; and the pappus bristles smooth, not “‘barbate,” as described
