Hortia brasiliana is a tree, 4 to 30 m tall.
It is the only species of the genus that is
found in eastern Brazil, distributed from the
states of Pernambuco and Bahia to Rio de
Janeiro and Sio Paulo. Along the coast, it
grows in the Atlantic Rain Forest and restingas
(coastal forest formations on sandy
soils near sea level); inland, it inhabits mesophyllous forests of the Planalto and
submontane forests of the Espinhaqo range
in Minas Gerais and Bahia. It is found at
altitudes from 50 m, on the coast, to 1120
m, in the Espinhaqo range. According to
Lorenzi (1998), this species is very frequent
in the Atlantic Rain Forest in Minas Gerais,
principally in the Rio Doce basin. The
western limit of this species appears to be
the Sio Francisco River.
The syntypes at Berlin (B), on which Engler
based his description of Hortia arborea,
were destroyed during World War II.
Although Engler (1874) cited "Riedel 468"
from the locality of Macah6 in Rio de Janeiro,
all probable duplicates bear the collector's
name, but no collection number nor
locality. No duplicates of Peckolt s.n. have
been found so far.
Hortia badinii M. A. Lisboa is a name
that appears on all specimens at the herbarium
OUPR (Universidade Federal de Ouro
Preto, Minas Gerais), including Badini s.n.
OUPR 7675, and in some publications (Waterman
& Grundon, 1983; Correa et al.,
1987). This name, according to information
from researchers at this herbarium, was
used by Lisboa to designate individuals of
Hortia with whitish (rather than pinkish)
trichomes on the inner surface of the petals.
Morphological analyses and field observations
of individuals in the vicinity of Mariana,
Minas Gerais (where Lisboa s.n.,
OUPR 26959, designated by Lisboa in
schedis as the type of H. badinii, was collected),
showed that this species does not
