Distribution and habitat:
—
Eugenia brasiliensis
is known from collections from the state of
Bahia
to
Santa Catarina
in the Atlantic rainforest of
Brazil
. The species is called popularly as “
grumixama
”, well-known and widely cultivated for fruit purpose in backyards. In the RNV,
Eugenia brasiliensis
is found in the
Mata Alta
vegetation.
Phenology:
—Flowering in September; fruiting in October through November (
Fig. 4
).
Taxonomic comments:
—The species is assigned to
Eugenia
sect.
Eugenia
.
Eugenia brasiliensis
is easily distinguished from all other species of the genus that occur in RNV by its raceme with late proliferation inflorescences with more than
10 mm
long (considering the sum of the peduncle and rachis length) with bracts with more than
9 mm
long and deciduous after anthesis, and flowers with calyx lobs 5–12 ×
3.5–5.5 mm
. Although the specimens
D.A. Folli 4674
and
D.A. Folli 7143
present fruits with a slightly costate surface, nonother discontinuous features were found to support their segregation – a possibility is that this character state could occur due to the drying procedure.
