year the leaves are gathered three times, in March, July, and 

 October.^ 



Other species of the genus Erytliroxylon are less used. In New 

 Granada, E, hondense " and areolatum ^ are mentioned as tonic medi- 

 caments, the buds, young shoots, and bark being used. The fruits 

 contain an acidulate, sweet, and mucilaginous juice, which is used 

 in preparing a dim'etic and purgative syrup prescribed for cutaneous 

 affections. In Brazil, E. subcrosttm* has an astringent bark producing 

 a reddish brown dye. A decoction of the roots of E. campestre ^ is 

 used in the same countries as an évacuant. The bark of the root 

 of E. anguifugum ^ is considered an alexipharmic. Most of the species 

 have a bright red wood ; that of E. hypericifolium '^ is the Bois 

 iVlmile (Oil wood), or de dames (ladies wood), or à halais (broom wood) 

 of the INIauritius which is used in cabinet work ; brooms arc really 

 made from the branches.
