This species yields, according to Wulfsberg, a valuable antidote against dysentery. 

 Vernacular name on the (lold Coast Kronii or Ghomi, in Lagos Ireno or male Ire. 

 It is very like H. africana; but the inflorescence is usually less hairy, the calyx 

 distinctly smaller, the flowers more slender with a slightly smaller limb, and scarcely 

 decurrent basal anther i)oints. 



29. PLEIOCERAS, Baill. in Bull. Soc. Linn. Paris, i. 759. 



Calyx small ; sepals 5, free or almost free, obtuse, imbricate, 

 alternating with scale-like glands. Corolla salver-shaped; tube cylin- 

 dric, short, with numerous variously shaped appendages in the mouth ; 

 lobes overlapping to the left, obtuse. Stamens inserted in the mouth 

 of the corolla ; anthers conniving in a cone, exserted, lanceolate, acute, 

 sagittate ; wings rather thin with thick incurved margins ; tails 

 slender, long, incurved ; foot of connective rather flat, with a decurrent 

 dense tuft of hairs in the centre ; filaments distinct, filiform, passing 

 into long slender slightly projecting ridges on the corolla-tube. Disc 

 0. Carpels 2, free; style filiform ; stigma capitate with a small basal 

 frill and a minute cleft tip agglutinated to the hair-tuft of the anthers. 

 Ovules pluriseriate, numerous. Follicles cylindric, slender, subparallel. 

 Seeds spindle-shaped, covered all over with long soft silky hairs, 

 densest at the base ; endosperm fleshy, scanty ; cotyledons convolute ; 

 radicle short. — Shrubs with slender branches. Leaves herbaceous, 

 opposite, with distant nerves ; axillary stipules ; axillary glands 

 minute, subulate, very scanty. Flowers small, in terminal minutely 

 bracteate many-flowered panicles. 



Species 3, endemic. 



Pleioceras is closely allied to Wrightia, of which I know only one sjH'cics from 

 Africa (Natal). It differs in the small flowers and the seeds, which liave not a dis- 

 tinct basal tuft of hairs, but are covered all over with long silky soft hairs, which 

 are densest at and near the base. The hairs are, in the follicle, directed townrds 

 the apex. 



Corolla-scales 10, 5 opposite to and 5 alternate with 

 the lobes, all from the mouth. 

 Scales ciliate ; pedicels up to 10 lin. long . .1. F. Afzeiii. 



Scales glabrous ; pedicels up to 5 lin. long . . 2. P. Barteri.
