This species seems to be common in Jamaica. I have the 
following specimens in my herbarium: Mandeville, A. E. Wight 
05, 96; Elizabeth G. Britton 437; J. A. Cushman 47; Catadupa, 
J. A. Cushman 14. I have compared one of the specimens col- 
lected by Wight with the type-specimens of Acharius in the Bo- 
tanical Museum at Helsingfors, Finland, and the determination is 
certain. Known elsewhere from Porto Rico and Peru.
