Common Name The Alien Pleurothallis [refers to the plant habit]

Flower Size 1" [2 cm]

Found in Boyaca department of Colombia in scrub cloud forests at elevations around 3200 meters mini-miniature sized, prolific, cold growing epiphyte with an elongate, creeping rhizome giving rise to erect ramicauls enveloped by 2 to 3 basal sheaths and carrying a single, apical, erect, narrowly elliptic, obtuse, gradually narrowing below into the petiolate base leaf that blooms in the spring on an erect, 1" [2.5 cm] long, single flowered inflorescence a with a much shorter than the pedicel floral bract.

"Similar to P longiserpens but differs in the morphology of the li pand its attachment to the column-foot. Instead of an elongated tip of the column-foot that protrudes into a cavotu at the abse of the lip, the truncate base of the lip is inflexibly attached to the column-foot." Luer 2006

Synonyms Andinia xenion (Luer & R.Escobar) Karremans & Mark Wilson 2017; Xenosia xenion (Luer & R.Escobar) Luer 2004
