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, 

 2^ 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 l-i 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, 3^ lin. long, 

 and the inner elliptic pair, 3 lin. long ; base of outer sepals acutely 

 decurrent on the pedicel.

 long. Sepals unequal ; 3 outer elliptic-ovate, obtuse, with subacute 

 base, aclnate to the pedicels nearly to the middle, about 2h lin. long,
