Specimens recently supplied by the Botanical Department, Jamaica, 

 collected by Dr. Dewar and Mr. George Douet, enable us finally to 

 determine this important timber-tree, the « Cogwood of Jamaica, 

 generically. 



Dr. P. Browne (I. c.) describes it as ' common in many parts of the 

 mountains,' and the wood as ' very toughand hard '--generally esteemed 

 one of the best in the island. Z. Chloroxylon differs &om the more 

 typical species of the genus in the absence of petals and in the com- 

 paratively thin pericarp, the inner stratum of which is b ony. The 

 fruit, however, is closely similar to that of Z. ^hphylla ^ Wall
