Common Name The Segovia Pleurothallis [Province in Nicaragua]
Flower Size .2" [5 mm]
Found in Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, Colombia and Ecuador at elevations of 350 to 2300 meters as a miniature sized, hot to cold growing, caespitose epiphyte on tree trunks in dense forests and open woodlands with slender ramicauls enveloped basally by 2 to 3, scarious, adpressed sheaths and carrying a single, apical, erect, oblong-ligulate, obtuse and retuse apically, gradually narrowing below into the conduplicate base leaf that blooms in the winter and spring on a solitary, arising from near the apex of the ramicaul, loose, secund, strict to flexuous, peduncle 1.2 to 2.4" [3 to 6 cm] long, rachis .8 to 5.6" [2 to 14 cm] long, simultaneously several to many flowered inflorescence with oblique, acute, as long as the pedicel floral bracts.
"Vegetatively this species is recognized by the densely caespitose, narrowly elliptical to obovate leaves borne by abbreviated ramicauls. The inflorescnece originated near the apex of the ramicaul and exceeds the length of the leaf, sometimes up to three times longer. The flowers vary in size, and they are borne more or less simultaneously to several at a time successivevly. The rachis varises from slightly flexuous to strict. Floral parts vary from green, yellow, orange, brown to purple. The membraneous sepals are variously pubescent within, and are sometimes totally hairless. The ptals are elliptical to oblong, more or less acute and about as long as the column. The lip is trilobes with the midlobe oblong ans obtuse and with prominent uncinate, basal lobes. A pair of lamellae occupies the middle thirs of the lip and at the base the surface varies from smooth to shallowly sulcate." Luer 1998
