I am referring Grisebach's species to that of A. Richard with 

 some hesitation, as did Grisebach himself (Cat. PI. Cub. 131. 

 1866), but specimens from Bahia Honda, Pinar del Rio (P. Wilson 

 9441) do not appear different from several from Oriente, including 

 a co-type (Wright 261) from Monte Verde.
