year tlie leaves are gathered three times, in Marcli, July, and 

 October.^ 



Other species of the genus Erythroxylon 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 

 ia preparing a diuretic and purgative syrup prescribed for cutaneous 

 affections. In Brazil, B. suberosum* has an astringent bark producing 

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

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

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

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

 d''huile (Oil wood), or de dames (ladies wood), or a halais (broom wood) 

 of the Mauritius which is used in cabinet work ; brooms are really 

 made from the branches.
