A low tree. Leaves alternate or 2-4 together on an aborted branch ; 

 leaflets obovate or obcordate, 1-2*5 cm. 1. Racemes usually about as long 

 as the leaf or a little longer, with numerous fragrant flowers, elongating 

 as the pods form. Sepals unequal, purplish, 4'5 mm. 1. Petals subequal, 

 6-7 mm. 1. Pod oblong, narrowing to both ends, 2-3-seeded, 3-5 cm. 1. 



After a hurricane which strips off the leaves, the tree soon bursts into 

 leaf again, and many of the leaves have leaflets enormously increased in 

 size, becoming about 7 cm. 1. and nearly as broad. 



The heart-wood is of a dark red or deep purple bronze-tinted colour, 

 and this alone is exported, together with the roots, as a dye-wood, the 

 whitish sapwood being chipped off. Sloane says that " it is cut about the 

 town of Carnpeche in great quantities, and brought to Jamaica in sloops 

 to be sent into Europe by the traders in Jamaica." Wright states that 

 Dr. Barharn introduced the seeds into Jamaica from Honduras about the 

 year 1715. Logwood is a mild astringent. It has been found useful in 

 chronic diarrhoea and dysentery, in some forms of atonic dyspepsia, and 

 especially in the diarrhosa of infants (Bentley and Trirnen). The tree 

 makes a strong fence against cattle. 



" Bastard " Logwood has a much lighter coloured heart-wood, yielding 

 little or no dye. There are no characters of leaf or flower which distinguish 

 it from the true Logwood. It may be considered a physiological species, 

 and trees should be destroyed wherever found. (See Bull. Torr. Bot. Cl. 

 xxxi. 367.)
