<i>Porroglossum hildeae</i> sp. nov. (Orchidaceae), a new species from the threatened cloud forests of northwestern Ecuador.

ABSTRACT: A new species of Porroglossum (Orchidaceae) is described and illustrated from the cloud forests of northwestern Ecuador. Porroglossum hildeae sp. nov. is morphologically similar to P. josei Luer, but can be distinguished by several features: it has narrowly obovate leaves reaching up to 9 cm in length (vs. elliptical, 4.5 cm), a longer dorsal sepaline tail measuring 6 mm (vs. 1.5 mm), oblong-ovate petals with one acute angle at the upper margin (vs. ovate with the upper and lower margins acutely angled below the middle), and the lip obtrullate, attenuate at the base, and acute at the apex (vs. obovate with the apex obtuse and abruptly acuminate). It grows epiphytically at approximately 1,600 m elevation in a cloud forest ecosystem that is increasingly threatened
