A new species of Pleurothallis in the P. cardiostola-P. lilijae complex of section Macrophyllae-Fasciculatae (Orchidaceae, Pleurothallidinae) from Ecuador and Peru
A new species of Pleurothallis subgenus Pleurothallis section Macrophyllae-Fasciculatae, recently discovered in upper montane cloud forests of the province of Loja, southern Ecuador, and the department of Amazonas, northern Peru, is described and illustrated as <i>P. labajosii</i> <b>sp. nov</b>. It is similar to other species of the <i>P. cardiostola-P. lilijae</i> complex, especially <i>P. alopex</i>, but differs from the latter in its oblong-lanceolate leaves; pale yellow to reddish-maroon, resupinate flowers; elliptic to elliptic-ovate, 5-veined dorsal sepal; ovate to ovate-triangular, 4-veined synsepal; recurved petals; and deep, triangular, minutely papillose labellum cavity with a deep, rounded glenion. A distribution map and information on the ecological preferences of the new species are provided.
