This is one of the commonest of the sparsely branched, round- 

 headed low trees or shrubs which grow scattered about on the savan- 

 nas in the northern part of the island where the soil consists of the 

 " Mai Pais" gravel. Its constant companions are Curatella americana, 

 Byrsonima crassifolia, and the palmettoes, especially Accelorraphe

Although the distribution as given above does not seem reasonable, 



. the characters given by Urban for his species agree very closely with 



the specimen from the Isle of Pines. The writer's field-notes have 



this to say regarding the color of the flowers: " Fls. rose-pink, with 



darker markings, and shading to cream-color in the throat."
