222 COMPOSITH (Harv.) [ Helichrysum. 
Root woody. Primary stems robust, woody, prostrate, throwing up herbaceous, 
short, laxly leafy fl. branches. Leaves 3-1 inch long, 2-3 lines wide, the nerves at 
first hidden by the thick wool. Heads occasionally solitary, mostly 3—4 in a corymb, 
4-5 lines diam., the inv. satiny-white. 
30. H. argyrospherum (DC. 1.c. 174); suffruticose, slender, branched 
from the base, diffuse or decumbent, branches cobwebby ; leaves sessile, 
linear-oblong or spathulate, narrowed at base, submucronate, one-nerved, 
cobwebby-villous; heads globose, many-fl., solitary at the ends of the 
branches and branchlets, sessile, surrounded by leaves ; inv. quiteglabrous, 
imbricated in many rows, the scales silvery-white, ovate-oblong, subacute 
or obtuse, erect or spreading, scarcely longer than the flowers.

Gariep, Drege! Natal country, Miss Owen! Aapjes River, Burke and Zey./—Zey.!

Root woody, many stemmed ; stems or primary branches 6—10 inches long, simple 
or branched. Leaves 7-1 in. long, 2-3 lines wide. Heads 4 lines diameter, very 
many flowered, much larger than in H. gariepinum. A specimen from Drege, in Hb. 
T.C.D., marked “ H. gariepinum, a.” belongs to this species; but specimens similarly 
marked, in Hb. Hook and Sd., are true H. gariepinuwm. 
31. H. obvallatum (DC. 1. c. 174); suffruticose, depressed, much 
branched and ramulous, tufted ; branches and leaves densely and softly 
woolly-canescent ; leaves linear-oblong or oblong, tapering at base, ob- 
tuse or subacute, crowded, scarcely nerved, the uppermost surrounding 
(like an involucre) the 1-3 sessile, terminal, many-flowered heads; inv.- 
scales glabrous and glossy, white or rosy-tipped, oblongo-lanceolate, 
acute, erect. i

Root woody. Stems rather strong, 3-5 inches long, spreading or prostrate, with 
erect, very short, leafy fl. branches. Leaves 5—7 lines long, 1-2 lines wide. Toment. 
_copious and white. Heads 3~4 lines diameter. 
32. H. pachyrhizum (Harv.) ; root-stock thick and woody, deeply 
descending ; stems many from the crown, spreading or prostrate, 
shrubby, branching and ramulous, tomentose ; twigs erect, leafy to the 
summit; leaves sessile, spathulate or lance.-linear, narrowed to the base, 
acute or obtuse, white-woolly ; heads one, or several-capitate at the ends 
of the branches, surrounded by several woolly leaves, 20-25-f1.; inv.- 
scales pluri-seriate, oblongo-lanceolate, acuminate, white or whitish, 
glabrous, glossy, scarious, straight or recurved,

Stock $ inch diam., several incheslong. Stems subhorizontally spreading, throwing 
up many tufted branches 1-2 inches long. Leaves }-$ inch long, very woolly. 
Heads solitary or several in a tuft. I venture to remove this plant from Leontonyz, 
and also to reject the very inapplicable name “ pusillus.” It is nearly related to H. 
leptolepis, but differs in habit. 
33. H. leptolepis (DC.? 1. c. 170); stem suffruticose (at first herba- 
ceous), branched from the base, the branches decumbent, simple or much
