108 COMPOSITE (Harv.) [ Pteronia. 
solitary, cylindr., 4-7-fl.; invol. scales broadly ovate, acute, appressed, 
3-5-nerved, dorsally downy, ciliolate. P. latisquama, DC. l. c. 363. 
Has. Hantum, Thunberg! Kamiesberg and Onder Bottkeveld, Drege/ (Herb. 
Th., D., Hk.) ee 
Scrubby, depressed, rigid, and small. Twigs very short and closely leafy ; 0 
branches glabrous. Invol. either pale-horny, or the scales glaucous-green at back, 
with horny edges. I find 7 fl. in some heads. 
43. P. empetrifolia (DC. 1. c. 363); very dwarf, ramulous, glabrous, 
viscidulous; leaves opposite, densely crowded on the short twigs, spread- 
ing, linear, keeled, flattish above or channelled, obtuse, thick, entire ; 
heads terminal, solitary, sessile, oblong-turbinate, many-fl. ; inv.-scales 
oblong, appressed, obtuse, opaque, horny, with a very narrow ciliate- 
lacerate margin ; achenes villous. 
Has. Cape, Drege! no station given. (Herb. Sond.) 
A very dwarf plant, 3-4 inches high. Internodes scarcely a line long. Leaves 
1-1} lines long. Heads 7 lines long. Inv. yellowish. FL purplish. I have only 
seen a fragment, 
44. P. heterocarpa (DC. 1. c. 364); glabrous, decumbent ; leaves 
opposite, connate, woolly internally at base, linear-elongate, obtuse, 
entire, fleshy ; heads term., solitary, sessile, campanulate, many-fl. ; 
invol. (shorter than the uppermost leaves) glabrous, dry, scales oval- 
oblong, obtuse, with a wide, membranous, lacerate margin ; outer 
achenes hirsute, inner quite glabrous. 
Has. Olifants R., Drege! (Herb. D., Hk., Sd.) : 
This looks like a salt-marsh plant, and is much less woody than most other species. 
Lower leaf-pairs distant, upper approximate. Lys. 1-1} inch long, 1-1} line wide. 
Heads 8-9 lines long and wide. Pappus foxy. 
45. P. viscosa (Thunb.! Cap. 632); divaricately much-branched ; 
twigs glabrous ; leaves opposite, but not connate, oblong or ovate-oblong, 
obtuse or acute, thick, flattish, with a medial furrow beneath, either 
rigidly ciliate, or sparsely bristly on one or both sides, or quite glabrous; 
heads terminal, solitary, sessile, oblong, several-flowered ; inv.-scales 
viscid, appressed, horny, the outer ovate-oblong, acute, the inner ob- 
longo-lanceolate ; achenes compressed, sparsely hispid. Pt. viscosa, litt.

Has. Hantum, Thunberg/ Zwart Ruggens, Drege! (Herb. Th., Hk.) 
A very rigid, scrubby bush, 6-12 inches high; branches spreading widely. Leaves 
3-4 lines long, 1-14 line wide, on the same branch varying as above noted. Invol. 
uncial, the inner scales much longer and narrower than the outer, very acute, almost 
acuminate. By its achene it is related to P. elongata, but has a very different 
involucre. 
46. P. elongata (Thunb. Cap. 631); twigs scabrous ; leaves opposite, 
sessile, crowded, linear-trigonous, keeled, acute, the keel and margin 
rigidly ciliate (or glabrous); heads terminal, sessile, obovoid, many- 
flowered ; invol. glabrous, viscid, scales broadly oval or oblong, ap- 
pressed, callous tipped, with a narrow, membranous, lacerate margin.
