_ Var. benguelensis, N. E. Br. Stems prostrate, leafy, glabrous or thinly pubescent 
with-spreading hairs (both forms in the same gathering). Leaves 2-5 lin. long, 13-4 
lin, broad, usually ovate, elliptic-oblong or elliptic, and broader in proportion to their 
length than in the type, rounded or subcordate at the slightly unequal base, glabrous 
on both sides. Involucre-glands with distinct petal-like appendages. Ovary glabrous. 
Otherwise as in the normal leafy prostrate specimens of the type.—E. Pogget, var.,

Var. villosula, N.E. Br. Stems, ovary, and capsule pilose or tomentose. Leaves 
on the fully developed prostrate stems as in var. Lenguelensis, more or less pilose or 
pubescent beneath or glabrous on both sides. Involucre-glands varying with very 
large to very small petal-like appendages, or sometimes without them and occasionally 
vith them well developed and quite absent on the same plant.—Z. villosula, Pax in

the o widely distributed species varies very much in appearance and pubescence,

Gay tufted stems, often with reduced leaves, which spring up after the

Shei mens from Angola have broader and more ovate leaves than the eastern 
*pecimens, whilst the secondary growths are indistinguishable ; the forms gradually 
-rsraee one another. As specimens with pubescent and glabrous stems occur in the
