Browne (1756) refers to it as cogwood or green heart. He calls it 
urus Chloroxylon, L., and gives a tolerably good figure of the leaves 
and fruit (p. 187, t. 7, fig. 1). He adds, “It is common in many parts 
of the mountains, and rises by a strong branched trunk to a very con- 
* siderable height. The inward bark is of a light blood colour, and 
* jneloses a strong greenish timber within the sap. The leaves are

At i me of the compilation of the Flora of the British West 
e Doni by Dr. Grisebach in 1864 this plant was known not 
aurus, but its exact potition was still undetermined. In ps 
Q. m P 285), Grisebach states, “ Laurus Chloroxylon, L. (Sl. t. 197, 
r. Jam E f. 1), a valuable timber-tree in Jamaica, fro rom the 
z ae s quoted i is no Laurinea. Upon Nees’s authority it belongs to

* which from their 3-nerved leaves had been compared with 
* Cinnamomum, though they are alternate and stipulate.” 
For the last 10 years efforts have been made by the Botanical 
Department, Jamacia, to procure good herbarium s cimens, embracing 
flowers and fruit, of cogwood. Owing however to the scarcity of trees 
of large size, this has been a fe of consider able difficulty. At last 
good specimens have been received at Kew through Mr. W. Fawcett, 
LS, Director of Public arth and Plantations, Jamacia, ict 
writes as follows: * I am at last sending you full material of. c cogw
