150 ME. BENNETT ON THE KOBO-TREE. 



tuso. Legwmen . — Arbor Africa? Occidentalis, Hymencece 



facie. Folia bifoliolata, foliolis S-5 -nerviis. Paniculse termi- 

 nales ; floribus in ramulis ultimis approximatis, sessilibus, 

 ineonspicuis. 



This new genus belongs to the Suborder Ccesalpinece, and is 

 evidently very nearly related on the one hand to Copaifera and 

 Cynometra, and on the other to Hymencea, TracTiylobium and 

 JPeltoyyne. It differs from the three latter genera in the total 

 absence of petals, in the complete suppression of the tube of the 

 calyx, and in its closely approximated sessile flowers. In these 

 particulars it approaches Copaifera, from which it is technically 

 scarcely to be distinguished by any other character than the 

 remarkable one of its two large persistent lateral bracteae, and by 

 its bifoliolate leaves ; which last-named peculiarity is, however, 

 found in one or two species of Copaifera. It thus forms a connect- 

 ing link between Hymencea and its subdivisions on the one hand, 

 and Copaifera and Cynometra on the other. As one of the trees 

 producing a valuable kind of Copal, it cannot be more appropri- 

 ately dedicated than to the learned Pharmacologist to whom we 

 are indebted for so many elaborate investigations into the origin 

 and history of substances used in Medicine and the Arts.
