66 composit#& (Harv.) [Gymnostephiwm. 
pedunc. in this species is rough with short, spreading, glandular bristles ; in M. 
taxifolia, thinly clothed with soft, cobwebby hairs. 
7. M. microcephala (DC. 1. c.); stem half-shrubby, erect, branched ; 
leaves linear, ciliate or pubescent ; pedunc. glandularly bristly ; heads 
small; invol.-scales few, subacute ; achenes pilose. Elphegea micro- 
cephala Less. Syn. 184. 
Has. Cape, Mundt & Maire, Burchell; Zeederberg, Drege! Zwellendam, Ecklon; 
Zwarteberg, Zey./ 2751. (Herb. Hk., Sd.) 
Very similar to the preceding, but smaller in all parts, with much smaller heads. 
Peduncles naked, 2~4 inches long. 
8. M. foliosa (Harv.) ; stem half-shrubby, corymbosely much- 
branched, branches spreading, leafy to the swmmit; leaves linear, ob- 
tuse, ciliate and pilose ; heads small, subsessile, ending leafy branches ; 
invol.-seales few, subacute ; achenes pilose. 
Has. Seekuvallei, #. Z.! Hott. Hollandsberg, Zey./ 2752. (Herb. Sd., Hk.) 
Nearly related to M. microcephala, but with quite a different aspect, 3-5 inches 
high, very much branched and ramulous, all the fiowering branches leafy to the 
summit. The dried specimens are glaucous, 
9. M. corymbosa (Harv.); shrubby, robust, erect, branched; leaves 
broadly linear-subulate or lanceolate-subulate, acute, flat, 3-nerved, 
ciliato-serrate ; pedune. numerous, corymbose at the ends of the branches, 
scabrous, pluribracteate ; involucral scales. 3-seriate, lanceolate, acute, 
glabrous, ciliate, 3-ribbed; achenes of ray densely cano-pubescent. 
Has. Near the mouth of the Klyn R., Zey./ 2742. (Herb. Sd., Hk., D., Cap.) 
-Two feet high or more; the most robust and woody of the genus. Leaves 1-13 
inch long, 1-3 lines wide at base, the young ones erect, the old deflexed, all rather 
rigid, with immersed glands. The branches are leafy to the summit, and from the 
axils of the uppermost leaves spring many short (2-3 inch long) peduncles, each 
bearing several depauperated, scattered leaves or bracts. Invol. scales each with 3 
glandular rib-striz. Achenes of the ray with copious, plumose pappus. Almost 
identical in aspect and foliage with Gymnostephium corymbosum, but with a very 
different involucre, and copious feathery pappus ! cowed

10. M. Eklonis (Sond.); half-shrubby, erect, branched, all parts 
very rough with glandular bristles, and sparingly pilose; leaves linear- 
lanceolate, 1-nerved, acute, flat, on both sides scabrid, the younger also 
ciliate with long, soft hairs; peduncles short; heads many-flowered ; 
invol. scales acuminate; achenes densely silky. Homochroma Ecklonis, 
DC. 1. c. 324. 
Has. Near Tulbagh, Worcester, Z.§ Z./ Brackfontein, Zey.! (Herb. Sond.) 
More rigid and robust than any of the preceding section, with broader, flatter, 
and very scabrid leaves. The rays are yellow, on which character De Candolle 
founds his genus Homochroma: in all other respects this plant agrees with Mairea. 
XIV. GYMNOSTEPHIUM, Less. 
Heads many-fl., radiate; ray-fl. female, ligulate, in one row; disc-/l. 
tubular-funnel-shaped, 5-toothed, sterile (with perfect, bifid styles, but — 
abortive ovaries). Invol. scales imbricate. Achenes of the ray-fl. plano- 
compressed, rib-margined, beakless, glandularly-scabrous on the dis¢; _
