"Palmorchis yavarensis belongs to a small complex of species characterized by robust plants with large leaves and a distinct narrow acuminate lip. Two members of the complex are P. carlos-parrae Szlach. & Baranow and P. maguirrei, from which P. yavarensis differs in its glabrous bracts and lip morphology. Palmorchis carlos-parrae from Colombia has the largest flowers of the genus with sepals 1.28” [32 mm] long and lip 1.04” [26 mm] long, entire and glabrous with a broad midlobe, .16” [4 mm] wide. Palmorchis yavarensis, on the other hand, has sepals and lip up to 1.2 and 1” [30 and 25 mm] long respectively, the lip is scarcely pubescent, especially along the middle of the lamina, and the midlobe is .6” [1.5 mm] wide. Moreover P. yavarensis has obliquely triangular-ovate lateral lobes with ciliate margins, while P. carlos-parrae presents falcate, acute entire lateral lobes." Damain and Torres 2018
