This plant has been referred to the Tournefortia sericea of 

 Vahl, a species from the Antilles, known only from his short 

 description. It differs from it in its leaves not being glabrous 

 above, and being nearly sessile, in its much denser terminal and 

 pyramidal inflorescence (not axillary and dichotomously di- 

 vided). Its branches are nearly straight and simple, IJ line 

 thick, with axils j-lj inch apart ; the leaves are 1 J-2 inches 

 long, 1-1 i inch broad, on a petiole scarcely more than 1 line 

 in length. The terminal inflorescence is not pedunculated, 

 2i inches long, 1 inch broad, consisting of many alternate 

 branches 1-2 lines apart, each with very crowded short flori- 

 ferous branchlets 2-4 lines long ; flowers on very short pedi- 

 cels, crowded ; sepals 1^ line long ; tube of corolla 1;^ line long, 

 lobes of border -J- line long ; anthers cohering at their apex ; 

 the style, thickened at the summit, including the stigma, is 

 j line long ; the drupe in its structure quite conforms to the 

 generic character.
