366 xlviii. ROSACEA (Oliver). [Chrysooalanus. 



Upper Guinea. Numerous localities from Senegambia southwards, apparently 

 affecting maritime or swampy situations. 



Lower Guinea. Loanda aud Ambriz, Angola, Dr. Welwitsch! 

 Also in Tropical America. The " Cocoa Plum" of the West Indies. 



2. C. ellipticus, Solander ; DC. Prod. ii. 526; Very closely allied 

 to the foregoing ; varying from a low shrub to a tree of 30 ft. in height 

 (Mami). Leaves elliptical, broadly and obtusely pointed or obtusely 

 apiculate or simply obtuse, not broadly rounded or retuse as in C. Icaco, 

 in the narrower-leaved forms cuneately narrowed into the petiole ; 

 2-3 in. long, 1-lf in. broad; petiole 1-2 lines. Inflorescence shorter 

 than leaves in our specimens. Fruit the " size of a damson plum, with 

 a thick black skin" (Don).—C. Icaco, L. var. elliptica, Hook. f. in. Mart. 

 Fl, Bras. Chrysobal. 7. 



Upper Guinea. Senegambia! Sierra Leone, Don! Ibu and Grand Bassa, T. 

 Vogel! Lagos, Barter I Nun river, Mann I 



Lower Guinea. Congo, Dr. Smith! 



Probably common in Upper Guinea. What appears to be tbe same species (C. 

 guianensis, Klotzsch), occurs in Tropical America, whether introduced only I cannot 

 say. 



2. PARINARIUM, Juss. ; Benth. et Hook. f. Gen. Plant, i. 607. 



Calyx-tube short or elongate, uniformly narrowed below or more or 

 less gibbous, hollow or solid nearly throughout, lobes 5, obtuse and 

 imbricate or acute and sometimes subvalvate. Petals 5 (or 4), inserted 

 in mouth of calyx-tube, caducous. Stamens 7-co , perigynous ; fila- 

 ments shortly united at base, when the stamens are unilateral with a 

 toothed or entire margin around the calyx-tube continuous with the 

 sheath ; anthers ovoid or rotundate. Ovary inserted in the mouth of 

 the calyx-tube, hirsute, wholly Or partially 2-locellate, with 1 ovule in 

 each cell ; style basal. (Carpels occasionally 2.) Drupe ellipsoidal or 

 subglobose, with a bony 1-2-locular putamen. — Trees or shrubs. 

 Leaves alternate, coriaceous, entire, base of lamina or petiole frequently 

 2-glandular. Stipules linear or subulate, deciduous. Flowers cymose, 

 2-bracteolate, in axillary or terminal pyramidal or corymbose panicles, 

 rarely racemose.

 All of the following species, excepting one, are peculiar to Africa. 



A. Calyx-tube campanulate or turbinate, hollow, not or scarcely-gibbous, teeth acute. 

 ■ Antheriferous stamens usually 7-10, not exceeding the calyx. Buds enclosed be- 

 tween a pair of caducous bracteoles (§ Petrocarya).
