Conservation Status:
—
Bertolonia maculata
has an EOO of
73,894 km
² and AOO of
42,500 km
², and should be classified as “Least Concern” (LC), following
IUCN (2017)
categories. In
Bahia
, this species has been found in the conservation units “
Estação Ecológica Pau-Brasil
”, “
Reserva Particular do Patrimônio Natural Veracel
” and “
Reserva Biológica de Una
” but also within private properties
.
Notes:
—
Bertolonia maculata
occurs in the states of
Bahia
and
Espírito Santo
. In
Bahia
, the species is widely distributed in lowland rainforests (
Fig. 13b
) along the central and southern coast, with some specimens also collected inland, in this case in the southern region of the state, in low elevation areas (
100–450 m
), on rocky outcrops or at the base of trees (
Baumgratz 1990
). Collected with flowers and fruits between January and February, and June to November.
Bertolonia maculata
can be distinguished by the stem, petioles and hypanthium densely glandulose-villose (the trichomes
1.3–4 mm
long), petals with an apiculate apex and anthers dehiscing through an introrse pore with thickened margins. It is closely related to
B. marmorata
, and they differ mainly by the morphology of the anthers.
Bertolonia maculata
has anthers with a flat or slightly undulate surface, and dehiscing through an introrse pore with thickened margins (
vs
. undulate anthers with extrorse pores that do not have thickened margins).
Bertolonia maculata
is also similar to
Bertolonia carmoi
, and differs from it by the petals with an apiculate apex (
vs.
acuminate or acute in
B. carmoi
) and unappendaged anthers (
vs.
dorsally bilobed in
B. carmoi
) For more details see
Baumgratz (1990)
and
