margin rather irregularly crenulate, 44-5 in. long, 24-23 in. wide; 
petiole {-3 in. long, stout, channelled above, eglandular; stipules 
minute, ovate-acute, deciduous. Spikes terminal and in the uppermost 
axils, 2-24 in. long, rather stout, with a peduncle under } in. long, with 
rather lax male flowers above and 1-2 subsessile basal female flowers, 
bracts in both sexes 1-flowered, males rounded, shortly apiculate, 
denticnlate, with a large oblong basal gland at each side, females 
oblong, acuminate, 2-glandular at the base. Male: Calyx deeply 
3-partite; lobes ovate-lanceolate, inflexed at the tip. Stamens 3, 
exserted. Female: Calyx 3-sect; lobes wide-ovate, acute, denticulate. 
Ovary glabrous, not horned ; styles 3, more or less connate at the base, 
Capsule thinly crustaceous, very large, 2 in. across, breaking up into 
three 2-valved cocci; fruiting pedicel very short. Seeds globose, brown, 
faintly blotched, with a caruncle which separates from the seed and 
remains adnate to the columella.—Hacecaria Bussei, Pax in Engl.

Zambesi ; Boruma, Menyharth, 746! 
A very distinct species. Menyharth’s specimens from Boruma only differ from 
those in German East Africain having the styles somewhat more distinctly connate 
at the base, and in having a slightly narrower ovary.
