Remarks.
Liparis brachystalix
is quite constant morphologically, having ovate, petiolate leaves with undulate margins, and labellum with a cordate base, apiculate apex, and a simple callus formed by thickened veins. Labellum shape varies slightly, being somewhat panduriform in the type of
L. pothoides
(Fig.
3B
) to obovate-oblong in those of
L. fendleri
,
L. commelinoides
and
L. brachystalix
(Fig.
3A, C, D
).

In Peru,
Liparis brachystalix
was collected in the 1960s in the cloud forests of Amazonas, but it was overlooked (Brako and Zarucchi 2993;
Ulloa Ulloa et al. 2004
,
2017
). In a recent update of the checklist of Peruvian orchids of
Zelenko and Bermudez (2009)
published by
Goicochea et. al. (2019)
,
L. brachystalix
was recorded for the first time in Peru. However, the record by
Goicochea et al. (2019)
did not indicate any vouchers supporting it. Therefore, herein we provide the first vouchered citation of
L. brachystalix
for this country.
Liparis brachystalix
is widespread along the eastern slope of the Peruvian Andes, inhabiting the cloud forest of Amazonas, Pasco, and Huancavelica at an altitude of 2000-2900 m.
