3. H. sepalosa, Rendle. A shrub, apparently erect, with (in the 
single specimen seen) pseudo-dichotomous branching. Branchlets stiff, 
woody, ascending, covered with brownish-grey bark, splitting in longi- 
tudinal areas. Leaves fascicled on dwarf-shoots, cuneate-spathulate, 3-4 
lin. long, apex emarginate, subsessile, sparsely pilose on lower surface 
and margin with the characteristic adpressed hairs, Flowers tetramerous. 
Male with subequal sepals about 1 lin. long, the two outer orbicular, 
the two inner slightly smaller and elliptic, blunt, pubescent on the 
back. Corolla funnel-shaped, a little over 3 lin. long, 4-fid to about the 
middle; lobes ovate, sparsely hairy in the median area on the back. 
Anthers oblong. Ovary rudimentary ; styles exceeding the stamens, 
21 lin. long; stigmas somewhat horseshoe-shaped, lobulate. Female 
flowers on filiform pedicels, 3 lin. long and sparsely hairy. 2 outer 
sepals, broadly elliptic, nearly 3 lin. long, apex rounded, base sub- 
acute, adnate to the pedicel in the lower third, sparsely pubescent on 
the back; 2 inner sepals elliptic, blunt, reaching to the margin of the 
outer, a little over 1 lin. to 1} lin. long. Corolla as in the male ; 
staminodes filiform, glabrous; anthers aborted. Ovary subglobose; stigmas 
as in H. africana. Immature fruit, 4-seeded, semiglobose, enveloped 
in the larger membranous suborbicular outer pair of sepals, 34 lin. long, 
and the inner elliptic pair, 3 lin. long; base of outer sepals acutely 
decurrent on the pedicel.

iv. 34, 20. A woody climber with spreading lateral branches; the 
slender elongated climbing shoots brown; final branchlets short; the 
older rigid, with grey to blackish, longitudinally splitting bark. Leaves 
very small, subcoriaceous, 3—5 lin. long, 1 lin. or a little more broad, 
spathulate, obtuse with mucronulate apex, glabrescent, ylaucescent. 
Female flowers few, fascicled on the leafy dwarf-shoots ; bracteoles 
minute, filiform, silky like the short pedicels, which do not exceed 14 lin. 
long. Sepals unequal; 3 outer elliptic-ovate, obtuse, with subacute 
base, adnate to the pedicels nearly to the middle, about 24 lin. long, 
bearing a few of the characteristic adpressed hairs; 2 inner minute, 
ovate-lanceolate, acute. Corolla 2 lin. long, deeply 5-partite ; lobes 
lanceolate. Staminodes slender, broadening slightly downwards, 2 lin. 
long, glabrous, exstipulate; anthers aborted; ovary bluntly ovoid,
