Common Name The Simple Stemmed Myoxanthus
Flower Size .15" [3 mm]
Found in Venezuela and Guyana in montane forests and on tepuis at elevations of 800 to 1900 meters as a small to just medium sized, warm to cool growing epiphyte with erect, slender ramicauls enveloped basally by 4 to 5, long, tubular, hispidulous sheaths and carrying a single, apical, erect, coriaceous, narrowly ovate, acute, narrowly cuneate below into the subpetiolate base leaf that blooms in the winter through summer on a succession of single flowered inflorescence arising from a dense mass of old nodes and peduncles at the apex of the ramicaul with infundibular, minutely pubebescent, as long as the pedicel floral bracts.
"Distinguished by the strictly caespitose habit with slender ramicuals and narrow leaves. Although superficially similar to Myoxanthus scandens , the small flowers are disinguished by the minutely pubescent sepals and petals with a more acutely defined, thick, apical segment, The lips of both species are similar."
