VICIACEAE. 



THE MEXICAN AND CENTRAL AMERICAN SPECIES OF 



BENTHAMANTHA. 



The name Cracca of Benthani being* a liomonym, the genus was 

 renamed Brittonanira by Otto Kuntze, hut he afterwards took up the 

 older name Benthaniantha published by Alefeld in 18G3. This latter 

 cour.se has been followed by Britten and Baker who pul>lished in the 

 Journal of Botany for January, 1900, a list of all tlu^ known species. 

 I wish to make a few slight changes in thif^ list, addnig also two new 

 species.
