Abstract

BAQUERO R., Luis E.  and  GALARZA VERKOVITCH, Denisse. Two new species and new records of Platystele (Pleurothallidinae: Orchidaceae) from Los Cedros Reserve en Ecuador. Lankesteriana [online]. 2019, vol.19, n.1, pp.5-13. ISSN 1409-3871.  http://dx.doi.org/10.15517/lank.v19i1.36900.

Two new species of Platystele were discovered at the orchid-rich forest of Los Cedros Reserve at North-west Ecuador. Many species of orchids grow in these forests and some endemic to it. Platystele cedriensis is similar to P. rhinocera from which it differs in the horizontal to descending inflorescence and the three-veined dorsal sepal. Platystele decouxii presents flowers with a unique heart-shaped lip with a heart-shape depression in the blade of the lip. We warn that on-going mining activities and concessions put in risk these and other endemic species from Los Cedros Reserve.

Keywords : Carchi; especies simpátricas; Orchidaceae; Platystele cedriensis; Platystele decouxii; sympatric species.
