1. P. rostrata, Benth. in Hook. Ic. Pl. t. 1182. A shrub, 8-12 
ft. high; young branches dark brown; lenticels few, rather large. 
Leaves oblong to elliptic, very shortly acuminate, acute at the base, 6-8 
in, long, 3-34 in. broad, coriaceous, glossy above ; secondary nerves 7-9 
on each side, distant, oblique; petioles 3 lin. long. Flowers few in each 
cluster. Calyx 1 lin. long; sepals acute or subobtuse. Corolla white; 
tube 9-11 lin. long; lobes oblong, rather broad, obtuse, as long as the 
tube or somewhat shorter. Carpels 3, 4-ovuled. Berries oblong-ovoid, 
rostrate, 14 in. long (including the beak), rather fleshy and coarsely 
rugose.—K. Schum. in Engl. & Prantl, Pflanzenfam. iv. il. 135, fig. 52,

A specimen collected near Bipinde, in the Cameroons, by Zenker (11818 !) and 
enumerated by Hallier, le., 194, under Hunteria pleiocarpa, agrees (so far as the 
material goes) exactly with Mann’s specimens of P. rostrata, except that the young 
fruits do not show any indication of a beak. The ternate mericarps are quite 
obtuse, but contain like those of P. rostrata 4 ovules in 2 collateral rows, I have 
not seen flowers of this plant, which is (according to Zenker) a small shrub, about 
3 ft. high, with white flowers. 
2. P. mutica, Benth. in Hook. Ic. Pl. t. 1181, A shrub, 5 ft. 
high; branches dark brown; lenticels few, rather large. Leaves 
elliptic or oblong, abruptly acuminate (acumen linear, obtuse, up to 7 
lin. long), acute or subacute at the base, 3-6 in. long, 14-2} in. broad, 
thinly coriaceous, glossy above; secondary nerves 11-14 on each side; 
petiole 3 lin. long. Flowers in axillary clusters of 10-20, often from
