prominentera crenatis, utrinque pallidis, glaberrimis, venis 
prominentibus, valde reticulatis, et in areolis sub lente nii- 
nutissime punctulatis; petiolo tenui, apice paulo tumidulo, 
limbo 6-plo breviore. — In Antillis : v. s. in kerb. De Cand.,

This species differs from all the preceding in the much larger 
dimension of its leaves, the sinuose crenulations of their mar- 
ginal nerve, and the relatively much shorter petiole. Although 
the specimen has neither flower nor fruit, there can be no doubt, 
from its habit, the texture and venation of its leaves, and its 
locality, that it belongs to this genus and is closely allied to 
Hyperhana Domingensis. It was sent to Prof. De Candolle 
by M. Balbis in 1820, and was found climbing to the loftiest 
trees. Its internodes are about 2 inches long ; the leaves are 
6^ inches long, 3 inches broad, on a petiole 1 inch long, which 
is articulated in the very prominent cup-shaped node of the 
axil : the surface of the leaves on each side, in all the deepened 
areoles of the small prominent reticulations, appears frosted 
when seen under a lens, and marked with very minute impressed 
dots — a feature seen also in some of the other species, where it 
is less marked.

Jamaica : v. s. in herb. Dr. Alex. Prior, (Jet ? (Prior). 
A very distinct species, remarkable for the comparative small- 
ness of its leaves upon very long slender petioles, and its many 
superimposed panicles. The axils are ^-| inch apart ; the leaves 
are 2-2^ inches long, 1-1^ inch broad, upon slender petioles.
