Frutex ad ripas fluviorum et vulgo in locis inundatis crescens. 
Ramuli elongati, foliorum paribus distantibus. Stipulæ brevissime, 
late, acute.  Petioli breves. Folia 3—5 poll. longa, 1—2 poll. 
lata, basi raro acuta; venæ primariæ irregulares, pagina inferior 
glaberrima sed squamulis minutis rufescens. ^ Pedicelli subses- 
siles, solitarii v. gemini, 4—5 lin. longi, uti rhachis tomento 
minuto rufescentes.  Bracteæ minute. Calycis laciniæ breves, 
late, pube appressa rufescentes. Petala valde inæqualia, pallide 
rosea. Antheree luteæ. 
This species is also near the B. Zzvigata, but the branches are 
not compressed, and the appendages of the anthers are reduced to 
minute points.

- The leaves are rather smaller than in the St. Vincent's speci- 
mens thus determined in my herbarium by M. de Jussieu, more 
shining, and without any trace of hairs even in their young state, 
but the peculiar anthers, small petals, &e., are - those of 
D. densa.
