250 CLIV. ERIOCAULEH (BROWN). | riocaulon. 
Said to be allied to Z. huillense, Engl. & Rubland, but differing in its larger 
leaves and heads, pure white sepals, longer female petals and narrow equal male 
petals. I have not seen it. See note under LZ. lacteum, Rendle, p. 246. 
22. E. huillense, Hngl. ¢: Ruhland in Engl. Jahrb. xxvii. 78; 
not of Rendle. Leaves short, ?—-1} in. long, at the base 2 lin. broad, 
above 4—} lin. broad, lanceolate, obtuse and somewhat thickened at the 
apex, about 9-11-nerved, glabrous. Peduncles 2-3 to a plant, several- 
ribbed ; their sheaths twice as long as the leaves, glabrous. Heads 
white-villous at the summit. Involucral-bracts ovate, subacute, 
glabrous or very sparsely pilose on the margins, yellowish-fuscous. 
Flowering-bracts similar to the involucral-bracts. Receptacle pilose. 
Female flowers: Sepals 3, green at the tips, ciliate. Petals 3, much 
shorter than the sepals, shortly spathulate, hairy all round, white, with 
a gland near the apex. Male flowers shortly pedicellate. Sepals 3, 
free, shorter than the petals, ovate, green at the apex. Petals unequal, 
broad, ciliate, with a gland near the apex. Anthers black. 
Lower Guinea. Angola: Huilla, Antunes. 
Said to be allied to #. Teusezii, Engl. & Ruhland, and from description appears 
to be near FE. Bauri, N. E. Br., from South Africa. I have not seen it, and do not 
understand the use of the term lanceolate as applied to the leaf, which is stated to be 
only # millimetre broad in the upper part. Probably the sepals are dark olive 
or fuscous at the apex, rather than green as described. 
23. E. afzelianum, Wikstr. ex Koernicke in Linnea, Xxvil. 680. 
Stemless, Leaves 7-15 to a plant, ascending, 4-1} in. long, 3-2 lin. 
broad, linear, acute or subobtuse, 4—10-nerved, glabrous. Peduncles 
very variable, 1-20 to a plant, 3-9 in. long, acutely 45-angled, 
glabrous, their sheaths 1-2 in. long, acute, glabrous. Heads 14—2} lin. 
in diam., subglobose, monecious, with the sexes intermixed, whitish, 
slightly ochreous or greyish. Involucral-bracts 3—1 lin. long, 4_2 lin. 
broad, oblong or cuneate-oblong, obtuse, slightly rigid, pale straw- 
coloured, glabrous. Flowering-bracts about 1-14 lin. long, 3—-$ lin. 
broad, cuneate-obovate, acute or acuminate, incurved, ochreous OF 
fuscous, more or less densely pubescent with white hairs on the apical 
part. Receptacle pilose. Female flowers shortly pedicellate or sub- 
sessile. Sepals 3, subunequal, 7-1 lin. long, 1} lin. broad, ochreous oF 
fuscous, bearded with white hairs on the apical part; the lateral pair 
linear-falcate, boat-shaped, obtuse ; the odd sepal cuneate-linear, obtuse, 
nearly flat. Petals 3, unequal, inserted above the sepals and exceeding 
them, the largest } lin. long, 4-1 lin. broad, oblanceolate, cuneate 
at the base, obtuse, rather thick and somewhat spongy, white, some- 
times slightly tinted with fuscous at the apex, slightly pubescent with 
white hairs on both sides or more densely so on the back, ciliate at 
the apex, glandless; the other two similar, but smaller, thinner and 
less hairy or nearly glabrous on both sides. Male flowers shortly 
pedicellate. Sepals 3, }-1 lin. long, more or less connate into a funnel- 
shaped body open down one side, and trifid, with unequal obtuse 
lobes, or sometimes free, ochreous or fuscous, pubescent with white
