I regarded this originally {loc. cit.) as a "form" of 31. coccinea; but 

 subsequent examination has led me to distinguish it as the type of a new 

 species. In the first place, all the other so-called " 4-sepalled forms " 

 of 3£. coccinea have proved, like 31. dominicensis for instance, to be 

 imdoubted new species. Again, Villavicencio, where Mr. Sprague 

 found this 2:)lant, lies just to the east of the triple barrier of the 

 Cordilleras, where we should scarcely expect to find a species which 

 has its main distribution to the west of this barrier. The floral 

 material is, inifoi'tunately, imperfect ; but critical specific characters 

 are afforded by the complete glabrousness of the flowers — even the 

 immature ones, by the hairy covering of the interior of the corolla, 

 by the calyx, the long anthers, and also \>y the leaf-venation. 



Leaves about 7 cm. x 3"5 cm., the petiole not exceeding 7 mm. or 

 so. Calyx-lohes 8 mm. or longer. Anthef'smtheY more than 5 mm. 

 in length.
