Var. quinquefida, Engl. Jahrb. xxviii. 386. Perianth 5-lobed.—H. Johannis, 
var. quinquefida, Solms-Laub. in Engl. Pflanzenr. Hydnoracee, 7. 
Mozamb. Dist. German East Africa: Uhehe; hilly places by the River 
Lukosse, on the roots of Adansonia digitata, Linn., Goetze, 487. 
In Uhehe the type is called “ nyambo,” and the variety “ mulimbi.” A specimen 
at Kew collected by Messrs. James and Thrupp at Hahi, in Somaliland, probably 
belongs to this species, but as it is in a fragmentary state and destitute of the 
rhizome cannot be definitely named.

Rhizome fleshy, terete, bearing tubercles. Perianth 4-lobed; lobes 
elongate-lanceolate, fleshy, “‘ rosy-yellow inside” (Beccari), not hooked 
at the differently coloured apex; margins reflexed, sparingly bearded 
in the central part, elsewhere naked. Anthers 4, at first joined, after- 
wards scarcely contiguous, ochre-coloured.—Solms-Laub. in Engl.

central, white.—Solms-Laub. in Engl. Pflanzenr. Hydnoracee, 7.

fectly or imperfectly 3-6-celled ; ovules numerous, anatropous, horizontal 
or pendulous; styles connate into a column (gynostemium), free above. 
Capsule indehiscent or septicidal. Seeds often immersed in the inner 
layer of the endocarp, triquetrous or flattened by pressure, albuminous ;
