parts glandular and viscidulous. Heads at first terminal, becoming lateral by the 
lengthening of the branch, just beneath the head. Invol. pale horn coloured, Pappus 
very white, of many short, unequal scales. Drege’s specimen, referred by DC. to 
N. biennis precisely accords with Thunberg’s “ R. reflexa,” 
2. N. acerosa (Harv.); shrubby, erect, glabrous, viscidulous ; leaves 
linear-subulate, pungent, round-backed, furrowed above, gland-dotted, 
crowded, imbricating; heads terminal, solitary, sessile; inv. scales lan- 
ceolate, acute, viscidulous ; recept. honey-combed and toothed (scarcely 
fimbrilliferous); achenes long, slender, angular, glabrous; pappus of 
many short, slender, subulate scales, Polychetia acerosa, DC./ l.c. 285.

land, 7. Cooper! 733- - 
A strong growing small bush, 12-18 inches high ; branches curved, with rounded 
axils, the older ones quite bare; upper branches and twigs closely covered with 
erecto-patent leaves. Leaves j-1 inch long, not a line wide, rigid, emitting a balsam. 
Heads longer than the leaves, the inner iny. scales radiating. Ray-fl. not much 
longer than the scales, reddish brown beneath. Style-branches truncate, pencilled 
at the extremity. Anthers with long tails.—A very distinct species, especially by 
the characters of the receptacle. 
3. N. Dregeana (Harv.) ; stems forked, flexuous, twigs spiniferous ; 
leaves opposite, oblong-obovate, flattish, tomentose, the upper ones (at 
least) densely setoso-glandular along the margin ; heads terminal, soli- 
tary, sessile; inv. scales oblong, broadly membrane-edged, very obtuse, 
the innermost elongate, at length reflexed ; recept. fimbrilliferous ; 
achenes linear-prismatic, glabrous; pappus of many short scales. Rosenia 
spinescens, DC.! 1. ¢. 280. *

(Herb. Sond.) 
A scrubby, tomentose, glandular bush. Leaves } inch long, 2 lines wide, hoary 
above, deciduously woolly and gland-bearing beneath. This plant, erroneously referred 
to Rosenia by De Candolle, has all the gen, char. of a “ Polychetia.” The fimbrils 
of the recept. are much shorter than the achenes, slender and subulate. 
4, N. Garnotii (Harv.) ; twigs tomentose, leaves linear, coriaceous, 
sub-trigonous, spreading or deflexed, crowded, obtuse, appressedly canes- 
cent or nude; heads several together in tufts at the ends of the branches; 
inv. oblong, few-fl., scales appressed, obtuse, shining ; recept. fimbril- 
liferous ; outer ovaries villoso-canescent; pappus of many minute, subu- 
late scales. Polychatia Garnotit, Less.! Syn. 372. DO. 1. ¢. 285, 
Van. 8, denudata ; leaves glabrous or nearly so ; young twigs canescent. 
Has. Cape, Garnot! Zwartland, Drege! B. Cape, Bowie! (Herb. Sond., Hk.) 
_A small slender shrub, of which I have seen but small specimens. Leaves 2 
lines long, } line wide, squarrose. Heads 3 lines long, Pappus very minute. Fim- 
brils of the recept. obtuse, connate into honeycomb-cells, obtuse. 8. in Hb. Hook. 
agrees in all characters except pubescence, 
5. N. prostrata (Harv.); stem shrubby, depressed or prostrate ; 
branches elongate, glabrescent, viscidulous ; leaves opposite, linear-con- 
volute, obtuse, tomentose above, puberulous beneath ; heads sessile at 
the ends of minute, lateral, densely leafy twigs, solitary ; inv. scales 
oblong, obtuse ; pappus of many subulate scales. Polycheetia oppositi-
