Abstract: Elaphoglossum discolor was recently discovered
and collected on the Urucum plateau of the Brazilian state
of Mato Grosso do Sul, lying in the western outskirts of
the Pantanal ood plain. is is the southernmost distri-
bution of E. discolor in Brazil.

southernmost recorded distribution
Dryopteridaceae Herter is a fern family of pantropical
distribution (Tryon and Tryon ) comprising –
genera and about , species, most of which (ca. )
belonging to one of the four richest genera: Ctenitis,
Dryopteris, Elaphoglossum e Polystichum (Smith et al.
). In Brazil Dryopteridaceae includes ca. species
mainly distributed in South and Southeastern regions,
with belong to the genus Elaphoglossum (Prado et
al. ).
Elaphoglossum Schott ex. J. Sm. is one of the most
diverse genera of ferns, comprising ca. species,
and is mostly distributed in cloud forests (Moran ;
Vasco and Moran ). e center of diversity for the
genus is the Neotropic region, which includes three-
quarters of all species (Mickel and Smith ). More
specically, the Andean regions between Colombia
and Bolivia have the highest number of Elaphoglossum
species (Tryon and Tryon ). In Brazil, about
of Elaphoglossum species occur in montane habitats of
South and Southeastern regions (Windisch and Kieling-
Rubio ).
Smith et al. () reported that many Elaphoglossum
species are yet to be described, which is supported by
the recent publications of Melo and Salino () and
Kieling-Rubio and Windisch (), indicating that the
diversity of this genus in Brazil may be signicantly
higher than currently recognized.
e present study reports the rst record of
Elaphoglossum discolor (Kuhn) C.Chr. for the state of
Mato Grosso do Sul, Brazil.
e present study was carried out in the Urucum
plateau region (ʹ.ʺ S, ʹ.ʺ W), western
outskirts of the Pantanal ood plain, Mato Grosso do
Sul state. e examined material (Brazil: Mato Grosso
do Sul: Corumbá, July , Morro São Domingos –
Maciço do Urucum, C.R.Lehn, ) was deposited in
the herbarium CGMS of the Universidade Federal de
Mato Grosso do Sul and duplicates were sent to the
herbarium SP in the Instituto de Botânica de São Paulo.
e material was sent for expert identication.
Elaphoglossum discolor is a herbaceous species, with an
ascending rhizome clothed in linear-lanceolate scales,
sterile fronds ovoid-lanceolate with maximum size to
cm and fertile fronds lanceolate-shaped with maximum
size to cm (Figure ). According to Brade (), the
closest relative of E. discolor is E. riparium Brade, which
occur only in Goiás state in the central plateau of the
Brazilian shield and is distinguished from E. discolor by
equal-sized sterile and fertile fronds.
A total of eight individuals were found in a cerrado
sensu stricto on ironstone outcrops, distributed at two
points (ʹ.ʺ S, ʹ.ʺ W and/ ʹ.ʺ
S, ʹ.ʺ W) at a mean altitude of m above sea
level.
Previous occurrence records for Elaphoglossum discolor
were restricted to the Amazonian forest in the states
of Acre, Amazonas, Roraima and Mato Grosso (Brade
; Windisch and Kieling-Rubio ). According to
Pott et al. (), the Pantanal region is inuenced by
its surrounding phytogeographical provinces (of which

the Amazon forest is obviously important), which
could explain the establishment of E. discolor in the
area. e headwaters of several tributary rivers of the
Rio Paraguai (the main river of the Pantanal basin) are
located in the outskirts of the Amazon basin, creating
a potential corridor for Amazonian species throughout
the Pantanal (Pott et al. ).
Besides the physiognomic distinction between the
Amazon and the Pantanal oodplain (mostly savanna-
like formations), Elaphoglossum species commonly occur
in primary forests and are very sensitive to habitat change
(Tryon and Tryon ). However, some Elaphoglossum
species are resilient to anthropic disturbance, e.g., the E.
discolor populations of the present study being observed
in areas aected by mining. e western outskirts of
the Pantanal oodplain, including the Urucum plateau
represent the area with most inventories of ferns and
lycophytes in Mato Grosso do Sul state, totaling
species (Assis ). e present study reports the
Urucum plateau as the southernmost distribution of E.
discolor in Brazil (Figure ).
