long,

long, to
1.3 cm
in diam. (immature), base attenuate, apex obtuse, with persistent floral parts.
Flowering and fruiting:
—Flowering from October; fruiting from January.
Habitat and distribution:
—
Rain forests;
150–700 m
.
Madagascar

.
Taxonomic notes:
—
Anisophyllea masoalensis
is close to
A. fallax
, from which it can be distinguished by the single
type
of short hairs on young branches, the buds pubescent rather than pannose, the styles shortly pubescent at base, and the fruits obovate. In addition to the differences between
Anisophyllea masoalensis
and
A. fallax
noted above, the former has thinner leaves with more acuminate or caudate apices whose tips are up to
1.8 cm
long.
The epithet of this species is from the name of the peninsula (Masoala Peninsula) and also the name of the renowned Masoala National Park, where the
type
material was collected.
