Common Name The Insignificant Pleurothallis
Flower Size .2" [5 mm]
Michoacan Mx. as well as Guatemala, 2023m elev., 9.5 klm south of Uruapan, in old lava beds,
Found in Jalisco, Michoacan, Guerrero, Oaxaca and Chiapas states of Mexico as well as Guatemala at elevations of 1500 to 2200 meters as a creeping, mat forming, mini- miniature sized, cool to cold growing, shortly repent epiphyte on trees or lithophyte with near full sun. This diminutive species in found as small tufts or moss-like pads high up in trees, so it often goes un-noticed and has very short, slender, erect to reclining ramicauls carrying a single, apical, elliptic, obtuse, tridenticulate or emarginate apically, gradually narrowing below into the short, petiolate base leaf that blooms in the winter on 1 to several, arising from the apice of the ramicaul, .4 to .8" [1 to 2 cm] long, racemose, successively single, few [1 to 3] flowered inflorescence with a minutely glandular to scabrous, as long as the pedicel floral bract and carrying the flowers held at mid-leaf.
"Characterized by the shortly creeping rhizome, short ramicauls and thick, erect leaves that vary from elliptical to narrowly obovate. The inflorescence is shorter than the leaf, the peduncle bears the flower, sometimes followed by a second, or sometimes two flowers simultaneously, the floral bracti minutely glandular to scabrous, the sepals are glabrous and acute, the petals are acuminate and more or less microscopically erose and the dark red to purple lip is ovate and thick with a convex surface to either side of a shallow, medial groove." Luer 2006
In my experience this species is extremely small and easily overlooked in the wild, as it comes from open, tall forests with the plants growing in the upper branches and usually are only found on newly felled timber. One of my favorite plants to show friends the diversity of orchids, this on the small end of orchids and Grammatophyllum speciosum on the other.
