Notes
. ‒
Syzygium condensatum
is relatively common in the humid montane forests on the Central High Plateau, particularly around
Antananarivo
, at elevations of (500-)
1000-1500 m
.
The species is morphologically similar to
S. cuneifolium
, but
S. condensatum
generally occurs at higher altitudes (
1000 m
and above), individuals have less dense inflorescences, thinner inflorescence axes, and smaller leaves with subrigid venation. In contrast,
S. cuneifolium
occurs mostly below
1000 m
and has denser and more compact inflorescences, inflorescence axes that are quite pale and somewhat thicker, and leaves having highly prominent venation. Further field studies are needed to examine the relationships of
S. condensatum
and
S. cuneifolium
in more detail and determine what overlap, if any, occurs both geographically and reproductively.
