lectotype
, designated by
Wurdack 1993
: RB! [barcode 00541448]; isolectotypes: MB [n.s.], MG [n.s.], US! [barcode 00120382]).
Comments:—
This species is easily recognisable by the combination of ferrugineous indumentum (
Fig. 65C–D
), ovate leaf blades with flat surfaces, spreading, fuchsia corollas, strongly dimorphic stamens, and stamen connectives with developed ascending dorsal appendages (
Fig. 65E–F
). The only Peruvian species of
Meriania
with similar appendages in the stamen connectives is
M. microflora
. However, it can be differentiated by its liguliform projections on the apex of the petioles (vs. absent in
M. urceolata
), white petals
4–4.5 mm
long (vs. fuchsia and
14–20 mm
long in
M. urceolata
) and antepetalous stamen connectives with apically trilobed ascending dorsal appendages (vs. sagittate,
Fig. 65F
).
Distribution and phenology:—
Meriania urceolata
is widely distributed from
Venezuela
to northern
Peru
and western
Brazil
. In
Peru
it occurs in the department of
San Martín
in premontane forests at
800–1600 m
(
Fig. 16
). It has been collected in flower in January, November and December.
Nomenclatural notes:—
Triana (1871)
[1872] cited as types the specimens
Spruce 2757
and
4439
in
the protologue of
M. urceolata
, so both specimens were considered as
syntypes
conforming with Art. 9.6 of the ICN (
Turland
et al.
2018
). For this reason,
M. urceolata
was lectotypified by Chiavegato & Baumgratz (2011).
Ducke (1922)
cited
Ducke 14854
as type in the protologue of
M. paraensis
but without indicating any herbarium, so it must also be considered as a
syntype
conforming with Art. 9.6 of the ICN (
Turland
et al.
2018
). According to Art. 9.10 of the ICN (
Turland
et al.
2018
), we must consider that
Wurdack (1993)
made an inadvertent lectotypification of
M. paraensis
when he wrote “
Ducke 14854 (
holotype
RB)
” in his treatment of
Melastomataceae
for the Flora of the Guianas.
