18 SUPPLEMENT. 



[i. p. 177.] BURSERACEiE. 



Our original enumeration of the Mexican and Central American members of this 

 Order is exceedingly imperfect. Since its publication, however, the tribe Burserece 

 has been monographed by Dr. Engler in De Candolle's ' Suites au Prodromus,' vol. iv. ; 

 from which we extract the species recorded from within our area, together with their 

 distribution and synonymy, arranged according to their affinities.
