256 CLIV. ERIOCAULEE (BROWN). [ Lriocaulon. 
Petals unequal, minute, the largest 4-} lin. long, oblong-ovate. 
Anthers black. Seeds about 4 lin. long, oblong-ellipsoid, brown, 
glabrous. 
Mozamb. Dist. British Central Africa: Zambesi River, on an island at 
Victoria Falls, Kirk ! 
This is very near Z. ciliisepalum, Rendle, and may be only a robust form of that 
species, but it differs in appearance, in its stouter subulate leaves, more numerous 
and stouter peduncles, larger heads, larger flowers, and the slightly different form of 
the sepals and petals. 
32. E. ciliisepalum, Rendle in Cat. Afr. Pl. Welw. ii. 98. A 
small, tufted plant, stemless, apparently an annual. Leaves }—1 in. 
long, 4-4 lin. broad, very slender; filiform, glabrous. Peduncles 
3-1} in. long, filiform; their sheaths not exceeding 4-5 lin. 
in length, oblique at the mouth, acute, glabrous. Heads 1-1} lin. 
in diam., subglobose, truncate at the base, with a whitish involucre 
and blackish disk, few-flowered, monecious, with the outer flowers 
female. Involucral-bracts 3 lin. long, }—} lin. broad, oblong-lanceolate 
or elliptic-oblong, acute or subobtuse, glabrous. Flowering-bracts 
3-4 lin. long, 4-} lin. broad, ovate or elliptic to oblong-lanceolate, 
acute, glabrous, fuscous. Female flowers sessile. Sepals 3, equal, 
3-4 lin. long, } lin. broad, lanceolate, acute, very concave, sparsely 
ciliate along the margins, otherwise glabrous, fuscous. Petals 
3, arising close to the sepals, } lin. long, narrowly-linear, acute. Male 
flowers shortly pedicellate. Sepals united into a funnel-shaped body, 
open down one side, bifid or trifid at the apex, glabrous, fuscous. 
Stipes between the sepals and petals scarcely 4 lin. long. Petals 
rudimentary, triangular-ovate, with a blackish gland below the apex. 
Anthers blackish. 
Lower Guinea. Angola: Huilla; in damp fields in which maize has 
been cultivated, tear Lopollo, 5000 ft., Welwitsch, 2445! on spongy slopes of 
Morro de Lopollo, below the old fortress, Welwitsch, 24458! Huilla to Humpata, 
Johnston ! 
Johnston’s specimens are stouter, and have more numerous flowers in the heads 
than any of those collected by Welwitsch, but I find no difference in the structure of 
the flowers and bracts. 
33. BE. mutatum, V. #. Br. Stemless. Leaves 2-8 lin. long, 
4-} lin. broad, subulate, tapering toa fine point, glabrous. Peduncles 
numerous, from less than 1 in. to 41 in. long, 4—1 lin. thick, filiform, 
3—4-angled, glabrous ; their sheaths 3-10 lin. long, obtuse, often torn 
at the apex, rather loose in the upper part, with a long oblique mouth. 
Heads 1-2 lin. thick, subglobose, moneecious, with female flowers on the 
outside and male and female mixed in the centre, black. Involucral-bracts 
3-2 lin. long, about + lin. broad, oblong, obtuse, fuscous. Flowering-bracts 
3—} lin. long, 4 to nearly 3 lin. broad, elliptic-lanceolate, or lanceolate 
acute, concave, blackish, glabrous. Receptacle glabrous. Female flowers 
sessile. Sepals 2, about 4 lin. long and as much in breadth, obliquely
