It is possible that more than one species is represented by the names and specimens placed 

 here, but the material available for study is so imperfect that it is impossible to decide definitely. 



Doubtful species 



Trigonia laEvis Aubl. PI. Guian. 390. 1775. A species of northern South America, 

 reported doubtfully from Nicaragua and Panama by Hemsley (Biol. Centr. Am. Bot. 1:65. 

 1879). 



Trigonia rugosa Benth. Bot. Voy. Sulph. 74. 1844. Reported by Hemsley {loc. cil.) from 

 Central America, but probably incorrectly.
