Leo])oldville and also to occur in the Frencli Congo. I suppose it is the same plant 

 which De Wildeman called M. Heudelotii in Etudes Fl. Bas et Moyen Congo, i, 68, 

 although he does not refer there to the Malonetia sp. of his Notes Apocyn. Laticif. 

 Congo. If 1 am right, the Lower Congo plant can hardly be M. Heudelotii. 



2a. Alafia Whytei, ^Stapf. Branches terete, glabrous. Leaves 

 elliptic-lanceolate to elliptic-oblong, rather abruptly and subobtusely 

 acuminate, acute at the base, 4-8 in. long, 2 to over 3 in. broad, papery, 

 dull, glabrous with the exception of the very sparingly pubescent under- 

 side of the midrib ; midrib deeply channelled above, prominent below ; 

 secondary nerves 6-8, oblique, connected by very bold arches 4-6 lin. 

 from the margin, raised like the very loosely anastomosing veins ; 

 petiole 2-3 lin. long. Cymes many-flowered, collected in a very shortly 

 peduncled or almost sessile congested corymb, 1-2 in. in diam., very 

 delicately pubescent ; bracts broad ovate, obtuse, small ; pedicels about 

 1 lin. long. Calyx 1 lin. long, very delicately pubescent ; sepals ovate, 

 obtuse, 2 or 3 of them with a gland at the base within. Corolla white 

 (?), drying black, delicately velvety without ; tube up to 5 lin. long, 

 densely hairy below the stamens within ; lobes suborbicular, 3 lin. in 

 diam., hairy at the base. Anthers not reaching the corolla-mouth, 2 J 

 lin. long. Carpels delicately pubescent.

6a. Alafia parciflora, Stapf. Whole plant glabrous. Branches 

 very slender, terete, drying dark brown ; lenticels scattered, incon- 

 spicuous. Leaves oblong to elliptic-oblong, acuminate Cacumen narrow 

 subacute or obtuse, up to 6 lin. long), i-arely subobtuse, acute or 

 shortly acuminate at the base, 2J-4 in. long, 1-2 in. broad, papery, 

 dark green above, pale below ; secondary nerves about 7 on each side, 

 very slender, slightly raised below ; veins anastomosing very loosely ; 

 petioles 2-4 lin. long. Flowers in at first umbelliform, then racemi- 

 form few-flowered cymes, usually 1 or 2 out at a time; peduncle slender, 

 very short ; bracts very small and broad with narrow scarious margins ; 

 pedicels up to 1 lin. long. Calyx glabrous, 1 lin. long; sepals ovate, 

 obtuse with a small narrow gland at the base within. Corolla-limb 

 yellow (?) with a red pubescent centre ; tube red in the upper part, 

 slender, about 5 lin. long, hairy within just below the stamens, other- 

 wise glabrous ; lobes lanceolate-oblong, subacute, 3 J lin. long. Staminal- 

 cone 1 J lin. long, reaching to 1 J lin. below the corolla-mouth. Carpels 

 glabrous with the exception of the whitish-puberulous tips.

The flowers and inflorescences are similar to those of A. Benthamii, but the 

 foliage is totally different.
