glabrous except at extreme base. Fruit (immaposite
to three calyx lobes, shorter than calyx
lobes, the filaments connate for lower third. Ovary

Distribution (Fig. 46). Known only from the
type from forest at base of high bluffs of an igneous
rock mountain.
This new species belongs to section Hirsuta
and is closely related to the other species in that
section and in section Hymenopus. It is quite
distinct nonetheless, and easily distinguished by
the hispid pubescence of the stems, petioles, midrib
and lower part of the inflorescence rachis.
This type of hispid pubescence, common in the
genus Hirtella, does not occur in other species
of Licania. Licania hispida, with acute or only
bluntly acuminate leaves is also distinguished
from related species by the leaf shape.

Distribution (Fig. 25). A recent collection of
this species was made in Loreto Dept., Peru. Previously
it was known only from the Guianas and
from a single collection from western Brazil. It
adds to the growing list of species disjunct in
eastern and western Amazonia that are not found
in Central Amazonia, such as Licania guianensis
and Couepia parillo.
