DOUBTFUL SPECIES. 



C. OBOVATUM, G. Den; A. DC. Prodr. viii. 163. Branehlets nearly naked. Pe 

 tiole above an inch long; blade oborate-oblong, \-& in. long, acutely cuspidate, del- 

 toid at the base, rigidly coriaceous, gi'een and naked aboA'O, pale and naked beneath, 

 the main A'eins 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. naia- 

 lense, Sonder. 



Branches stout thinly coated towards the tip with whitish silky tomentum. 

 Leaves distinctl} petioled, oblanceolate-oblong, 6-6 in. long, l|-2 in. broad, emar- 

 giuate 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 

 joined at the tip by an intramarginal arch. Flowers in copious clusters, seen in veiy 

 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 

 this closely approximates to C. magalismontanuin. 



Achras scricea, Thonn. and Schum. PI. Guin. 179 (Sapota sericca, A. DC. Prodr. viii. 

 176), from L^^pper Guinea, of which the flowers are unknown, of which the leaves are 

 said to be lanceolate, reaching a length of a foot or a foot and a half, glossy on the upper 

 and argenteo-sericeous on the lower surface, and the petioles and branehlets pubescent, 

 may perhaps also belong to this genus.

 Calyx funnel-shaped ov 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 tho 

 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 

 coriaceous, ovoid or globose. Seed usually by abortion solitary ; testa 

 glossy ; albumen fleshy ; cotyledons foliaceous or thickened. — Erect 

 trees or shrubs, with the habit and inflorescence of Ghrijsophyllum, but 

 the leaves glabrous in all the Tropical African species and in some of 

 stipulate.
