Type. — Near Nueva Gerona, Isle of Pines, December 15, 1903, 

 A. H. Curtiss, No. 228, West Indian Plants. Specimen in the Her- 

 barium of the Carnegie Museum. 



The type specimen was issued as Acisanthera qiiadrata Jussieu, but 

 it very clearly differs from that species in a number of prominent 

 characters, it being much nearer to A. recurva (DeCandolle) Grise- 

 bach, which, however, has the basal spurs on the connectives of the 

 anthers blunt, and has 5-merous flowers and a 3-loculed capsule.^ 



The writer has not examined Blain s Nos. 70 and 162, collected in 

 the northern part of the island and referred by Millspaugh to Acisan- 

 thera quadrata Jussieu, but they in all probability are of the same 

 species as Curtiss' s No. 228. 



517. Tetrazygia bicolor (Triana) Cogniaux.
