segments. Petals 0. Stamens 10, free ; filaments glabrous j anthers 

 elliptical, versatile, dehiscing- longitudinally. Ovary shortly stipitate, 

 compressed ; style involute in bud, slender, stigma capitate ; ovules 

 2 (-4), superposed. Legume stipitate or sessile, flat or compressed, 

 falcate-ovate or somewhat semi-orbicular, coriaceous, 1 -seeded. Seed 

 exalbuminous, with or without an aril ; cotyledons plane plano-convex 

 or plicate. — Unarmed trees. Leaflets unijugate, coriaceous, very oblique. 

 Flowers in terminal or axillary panicles or racemes. 



Chiefly a Tropical American genus. The following species are peculiar to this Flora, 

 unless it be C. coleosperma. C. Mopane may prove generically distinct. 



Leaflets 1-nerved, penniveined 1. C. coleosperma. . 



Leaflets 3-4 nerved. 



Buds sessile, ellipsoidal ; bracteoles closely investing base of 



calyx 2. C. Guibourtiana. 



Buds subsessile, globose ; bracteoles obsolete 3. C. Gorskiana. 



Leaflets 7-9-nerved 4, C. Mopane. 



1. C. coleosperma, Benth. in Linn. Trans, xxv. 316, t. 43 A. A 

 large tree;' branches slender, wholly glabrous. Leaflets unijugate, 

 falcate-ovate or oblong-ovate, obtusely acuminate or more broadly 

 pointed, coriaceous, glabrous, strongly reticulate, 2-2J in. long, 1— lg 

 in. broad, petiolules about 1 line, petiole J— 1 in. Flowers (not seen) 

 in terminal and axillary panicles. Legumes much compressed, coria- 

 ceous, somewhat semiorbicular, glabrous, rugulose or finely tuberculate- 

 corrugate when dry, {— \\ in. long on a gynophore of 2-3 lines. Seeds 

 conspicuously arillate ; testa shining ; cotyledons plano-convex, uni- 

 form, not resiniferous. 



South Central. Batoka highlands, Dr. Kirk ! 



Dr. Kirk states that in some localities this tree " has been planted at least 100 years 

 ago." The red aril is used in preparing a nourishing drink. 



As pointed out by Mr. Bentham, this plant — so far as fruiting specimens enable one 

 to judge — is identical with the Cuban C. hymenaii folia, excepting in the aril. Are they 

 the same species? Which, if either, is the introduced plant? 



The leaflets in this species are more completely penniveined than in C. Gorskiana, 

 in which the nervation is that of Bauhinia, the principal nervures usually radiating 

 from the base. 



2. C. Guibourtiana, Benth. in Linn. Trans, xxv. 317. Tree ; extre- 

 mities rather stout sinuous rugulose, giving off numerous ascending 

 branches, puberulous or obsoletely pubescent at first. Leaflets 1 -jugate, 

 coriaceous, broadly semi-elliptical or -obovate, obtusely acuminate, 3-4- 

 nerved with subprominent reticulation, 2^-3 \ in. long, 1-1 \ in. broad, 

 sessile ; petiole 2 lines. Flowers numerous, sessile in panicled ascending 

 spikes, overtopping the leaves. Bracts ovate, 1—1 \ lines long, caducous. 

 Bracteoles truncate or broadly rounded, closely investing the base of 

 the calyx. Buds ellipsoidal, 2 lines long. " Sepals 4, imbricate, coria- 

 ceous, subequal in length, elliptical, obtuse, glabrous. Ovules 2—4." I 

 have not seen expanded flower or fruit. — Guibourtia eopallifera, Bennett 

 in Journ. Linn. Soc. i. 150. 



Upper Guinea. Sierra Leone, Dr. Daniell! 



Called Kobo tree by the natives. Said to afford a valuable copal. " Wood odoriferous."
