Information
Herb 20 in. high, more or less hirsute. Stems quadrangular. Leaves of the main stem sessile, lanceolate, auricled at the base, attenuate and acute at the apex, 3–7 in. long, 3/4–1 in. broad, the auricles 5 lin. long; smaller leaves stalked. Flowers white or pale purple, in dense clusters in the axils of the leaves, with thorns as in H. spinosa, which, however, are so short as to be hidden by the bracts and calyces; bracts and bracteoles lanceolate, acuminate, ciliate-hispid; spines 1/2 in. long. Calyx with the upper sepal 1 in. long, the others shorter; the lower pair fused almost to the tips. Corolla-tube about 1 in. long. Stamens unequal, with the filaments of the lower pair broadened, each attached to the filament of the upper stamen of its side at the base. Capsule 1/2 in. long, 8–10-seeded, elliptic-lanceolate.
Distribution
Congo South Central Evamkoyo; near Businga, Thonner.
Notes
Very closely allied to H. spinosa, T. Anders., if truly distinct. The authors call attention to the unusual number of stopples (viz. four) which they observed in the pollen. They describe the pollen as having about 20 lines running from pole to pole, and state that the pollen of H. spinosa differs in having fewer; but this is not always the case.
