Taxonomic notes
:—It is possible to differentiate
Tovomita spruceana
from
T. umbellata
Bentham (1843: 367)
only by vegetative characters.
Tovomita spruceana
has shorter internodes and leaf lamina and a longer petiole than
T. umbellata
. When in floral buds,
Tovomita spruceana
is distinguished by
T. umbellata
by its oblong floral buds with rounded apex (vs. ovate floral buds with acute apex in
T. umbellata
).
