 apicata.

 leaves broad-ovate, acuminated, attenuated at the base, shining, 

 quite glabrous ; panicles on long peduncles. Ij . S. Native of 

 the Antilles. Branches saffron-coloured, as in P. crocea, to 

 which it is very nearly allied, but differs in the flowers being 

 smaller and fewer, and in the nerves of the leaves being com- 

 mon, not parallel. The stipulas, flowers, and fruit remain un- 

 described. 



Crocea-like Palicourea. Shrub 4 to 6 feet.

 ish. Tj . S. Native of St. Domingo and Porto-Rico. Psy- 

 chotria coccinea, Poir. pi. exsic. Very nearly allied to P. crocea, 

 and is probably often confused with it, but differs in the corollas 

 and fruit being smaller, in the branches of the panicle being 

 erect and spreading, and usually alternate, in the stipulas being 

 shorter and thinner, &c. 



Scarlet Palicourea. Shrub 4 to 6 feet.
