DOUBTFUL SPECIES. 
C. osovatum, G. Don; A. DC. Prodr. viii. 163. Branchlets nearly naked. Pe 
tiole above an inch long; blade obovate-oblong, 4-6 in, long, acutely cuspidate, del- 
toid at the base, rigidly coriaceous, green and naked above, pale and naked beneath, 
the main veins fine and not raised. Flowers and fruit both unknown, Sierra Leone, 
G. Don. Vogel ! Closely resembles, so far as the material goes, the Cape C. nata- 
lense, Sonder. 
Branches stout, thinly coated towards the tip with whitish silky tomentum. 
Leaves distinctly petioled, oblanceolate-oblong, 5-6 in. long, 1f-2 in. broad, emar- 
ginate at the tip, deltoid at the base, rigidly coriaceous, naked above, thinly clothed 
beneath with persistent whitish silky tomentum, the numerous little-raised veins not 
Jomed at the tip by an intramarginal arch. Flowers in copious clusters, seen in very 
young bud only, distinctly pedicelled, the minute globose bud-calyx densely coated with 
adpressed light ferruginous silky tomentum. Madi woods, Col. Grant ! In habit and leaf 
Is closely approximates to C. magalismontanum.. es 
Achras sericea, Thonn. and Schum. Pl. Guin, 179 (Sapota sericea, A. DC. Prodr, viii. 
176), from Upper Guinea, of which the flowers are unknown, of which the leaves are 
said to be lanceolate, reaching a length of a foot ora foot anda half, glossy on the upper 
and argenteo-sericeous on the lower surface, and the petioles and branchlets pubescent, 
may perhaps also belong to this genus.

Calyx funnel-shaped or rotate, deeply 5- rarely 6-7-partite, the 
segments obtuse or subacute, imbricate, but not arranged in two dis- 
tinct rows. Corolla little longer than the calyx; segments as many 
as those of the calyx, entire, longer than the tube. Stamens as 
many as the corolla-segments and inserted opposite to them at the 
throat: of the tube; filaments subulate; anthers oblong or ovoid, 
usually extrorse; staminodes as many as the stamens and alternate 
with them, linear or linear-subulate, entire, small or as long as the 
filaments, Ovary globose, 5-celled; style subulate. Berry fleshy or 
Corlaceous, ovoid or globose. Seed usually by abortion solitary ; testa 
glossy ; albumen fleshy ; cotyledons foliaceous or thickened.—Erect 
rees or shrubs, with the habit and inflorescence of Chrysophyllum, but 
¢ leaves glabrous in all the Tropical African species and in some of 
stipulate.
