As to types 2 and 3 mentioned above, I consider that these 

 should be separated from Melastelma and made to constitute 

 separate genera. [N. hi. Brown\] 



Jacquemontia elongata Britton, sp. nov. 



A slender vine, up to 5 m. long or longer, the branches and 

 peduncles appressed-pubescent. Leaves ovate, membranous, 

 slender-petioled, glabrous or nearly so, about 7 cm. long or 

 shorter, the apex acute or acuminate, the base cordate, rounded 

 or subtruncate; peduncles 5-10 cm. long, much longer than the 

 petioles; inflorescence subcapitate, several-flowered; corolla blue 

 to lavender, about 1.5 cm. in diameter. 



Thickets, Trinidad, Tobago and northern Venezuela. Type 

 from Manzanilla, Trinidad {Britton 2 191). This plant has been 

 referred to J. pentantha (Jacq.) Don. 



Columnea tocoensis Britton, sp. nov. 



Stems rather short, simple or little branched, clustered, 1.5 

 m. long or less; long, appressed, pubescent. Leaves oblong, 3-4 

 cm. long, appressed-pubescent, obtusish. Peduncles densely 

 pubescent, 1.5 cm. long or shorter; calyx densely pubescent, 

 about 8 mm. long, its lobes lanceolate, acutish; corolla yellow, 

 about 4 cm. long, loosely villous with nearly white hairs, its 

 slender tube about twice as long as the limb. 



Pendent on forest trees, Trinidad. Type from Toco Road, 

 near Valencia {Britton, Hazen and Mendehon 1785). This is, 

 perhaps, the plant referred by Grisebach to C. scandens. 



Columnea aripoensis Britton, sp. nov, 



Branched, the branches rather stout, densely appressed- 

 pubescent, 2 dm. long or longer. Leaves oblong, short-petioled 

 2.5-3.5 cm. long, finely appressed-pubescent, obtuse; peduncles 

 densely villous, 8-12 mm. long; calyx 10-12 mm. long, appressed- 

 pubescent, its lobes ovate, acute; corolla red, 3-4 cm. long, 

 loosely pubescent with long jointed hairs, its tube gradually 

 expanded above, about twice as long as the limb. 



On trees, Heights of Aripo, Trinidad. {Britton and Free?nan 

 2340, type). 



Diapedium aripoense Britton, sp. nov. 



Branching, strigillose, 1 1.5 m. high. Leaves elliptic-ovate, 

 membranous, slender-petioled, rather strongly veined, long- 

 acuminate at the apex, narrowed at the base, the lower about 2 

 dm. long, the upper much smaller; inflorescence several-flowered,
