segments. Petals 5, oblong or elliptic-lanceolate, pubescent, with imbricate 

 margins. Stamens 10; filaments filiform with a narrow, adnate, pilose 

 scale on the inner face. Kudiments of the carpels immersed in a raised, 

 sulcate, glabrous, central disk. Female fl. : " Carpels 5-6. Styles connate. 

 Drupes 1-6," oblong, indehiscent, with a woody or bony endocarp, 1-seeded. 

 Seed conformable. Cotyledons fleshy, plano-convex, with a minute radicle. 

 — A small glabrous tree. Leaves alternate, unequally pinnate ; leaflets 

 coriaceous, opposite or alternate, often on long petiolules. Flowers small, 

 white, fragrant, in terminal alternately branched panicles. 



A genus of one, or perhaps two, species, peculiar to W. tropical Africa. I have only 

 seen male flowers and fruit. 



1. H. undulata, Planch, in Land. Journ. Bot. v. 566. Leaflets very 

 coriaceous, obovate- or elliptic-oblong, retuse minutely apiculate or obtuse, 

 subentire, narrowed or cuneate at the base, venation obscure, 2-4 in. long, 

 1-2 in. broad or occasionally larger. Petiolules 1 in. or less ; common pe- 

 tiole about 6 in. Panicles equalling or shorter than the leaves. Drupes f-1

Upper Guinea. (Petiolules near 1 in.) Senegambia I Niger, Barter ! (petiolules 

 about i in.) Mouth of the Niger, Mann ! 



Excepting the length of the petiolules, I see no noteworthy character separatiug these 

 two forms, which are referred to as distinct species in the ' Genera Plantarum.'

Flowers polygamous. Calyx 4- rarely 3-partite. Petals 4, rarely 3, ellip- 

 tical. Stamens usually 4, outside the disk, in the female flowers effete or 

 smaller ; filaments naked ; anthers rotundate, unappendaged. Female fl. : 

 Carpels 4, cohering at the top of the ovaries, each with a spreading or re- 

 curved style. Ovules solitary, attached above the middle. Drupes 4 or 

 fewer, ovoid, with a thin, scarcely fleshy pericarp. Seed conformable to the 

 Pericarp, exalbuminous, the cotyledons fleshy, plano-convex, sometimes co- 

 hering.— Trees. Leaves alternate, imparipinnate, exstipulate. Flowers 

 spicate or in elongate narrow panicles, very small.
