The numerous specimens collected b^^ Ramon de la Sagra 

 agree well with each other and with Wright n. 2792 in the 

 Kew Herbarium. The specimen from Loma Pelada, which is 

 the V. stictophylla Wright, appears to be only a shade form of 

 the species, being collected in »damp, shady woods». It has 

 greenish involucres, those of genuine V. havanensis often being 

 purple-tinged. 



Gleason in his Revision made no distinction between the 

 three species of Vernonim havanenses. I suppose he had not 

 seen the genuine V. hieracioides Griseb. at that time. In his 

 »Studies» he has three genuine Vernonim havanenses, viz. 

 V. havanensis DC. V.Ottonis Sch.-Bip. and V.Orientis Gleason.
