Full ShadeCold Fall Winter

Common Name The Porcupine Myoxanthus [An allusion to the hispid, cauline sheaths]

Flower Size .2" [5 mm]

Found in Colombia and Venezuela at elevations around 2300 to 2500 meters as a mini-miniature sized, cold growing epiphyte with erect ramicauls enveloped by 3 to 7, tubular, hispidulous sheaths and carrying a single, apical, erect, thickly coriaceous, narrowly elliptical-ovate, acute, cuneate below into the subpetiolate base leaf that blooms in the fall and winter on a fascile of .05" to .1" [1 to 2mm] long, single successive flowers arising from the apex of the ramicual with pubescent, as long as the pedicel floral bracts.

"Characterized by the long, creeping habit, slender leaves longer than the ramicaul, flowers similar to Myoxanthus reymondii, but with only slightly clavate petals and a revoluste lip with neither calli nor lobes as found in Myoxanthus melittanthus. The tips of the petals of Myoxanthus cimex and Myoxanthus reymondii are markedly clavate." Luer 1992
