Found in Venezuela, Colombia, Ecuador and Peru in montane forests at elevations around 3100 to 3150 meters as a medium sized, cold growing terrestrial with a basal, oblong-elliptic, obtuse, long petiolate base leaf that blooms in the fall on an erect, terminal, peduncle provided with 4 to 5, glabrous, tubular sheaths, ciliate, subdensely several flowered inflorescence with pubescent, ovate, obtuse, glabrous, a bit shorter than the ovary floral bracts and carrying flowers with dirty green sepals, transluscent, brownish yellow petals and yellow, brown veined lip.
"From all other Ecuadorian species of the nominal section of Pterichis, P. diuris differs in having glabrous ?oral bracts. In the presence of the auricles, the lip of this taxon resembles somewhat P. galeata which differs from P. diuris by obliquely elliptic petals which are not long-clawed." Kolanowska 2021
