is entirely so ; in this character it differs from most of its allies, 

 although glabrous examples of B. guianensis (q. v.) occur. The 

 critical characters of this Cuban species appear to be the obtuse 

 apex of the narrow leaf, which is lengthily acuminate at both ends, 

 the short corolla-tube, and the comparatively short and broad an- 

 thers, which have but a small apical continuation of the connective.

At once recognizable by the small size and large number of 

 the flowers, arranged in a lax thyrsus. The leaves in the avail- 

 able material, too, are conspicuously large — 22 cm. x 8 cm.

I have, unfortunately, not seen the type-plant, but from the 

 description I have little doubt in assigning Barclay's plant to the 

 same species. The stipules, sheathing for the greater part of their 

 length, and produced each into a long seta, which is decurrent as 

 a line of hairs down the middle face of the sheath, are very 

 characteristic. The general habit recalls B. angustifolia.

Hab. Guiana, in forest marshes : Bichard. Differs from 

 B. guianensis, according to the description, in having bifid 

 stipules and closely approximated lateral leaf-veins, and in its 

 almost herbaceous habit. I have not seen a specimen.

Its affinities are with B. guianensis, but its narrow leaves and 

 small berries are characteristic. The seeds, too, are less deeply 

 foveolate than in B. guianensis.
