4. Tricera acuminata Griseb. Nachr. Gesell. Wiss. Goetting. 1865: 



162. 1865 

 Buxus acuminata Muell. Arg. in DC. Prodr. 16 1 : 15. 1869. 



Type locality : Cuba. 



Distribution: Known only from the type specimens (C. 

 Wright 191 9, in part). 



5. Tricera brevipes (Muell. Arg.) 



Buxus citrifolia brevipes Muell. Arg. in DC. Prodr. 16 1 : 15. 1869. 

 Buxus brevipes Urban, Symb. Ant. 5: 400. 1908. 



Type locality: Cuba (C. Wright 1919, in part). 



Distribution: the label with Wright 191 9 in the herbarium of 

 the New York Botanical Garden gives the locality as San Diego 

 de Tapis; the following specimens appear to agree with it: upper 

 valley of the Rio Navas, Oriente (Shafer 4402) ; Rio San Miguel 

 below Mai Paso, Pinar del Rio (P. Wilson 9309). 



Referred by Grisebach to T. fasciculata Griseb., of Jamaica. 

 I am not confident that the species is distinct from T. acuminata.
