Common Name Seidel's Myoxanthus [Brazilian Collector of species current]

Flower Size .4" [1 cm]

Found in Espirito Santo Brazil in virgin forests at elevations around 1000 meters as a medium sized, warm to cool growing epiphyte with an ascending to erect, stout ramicaul enveloped by 4 to 7 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 on a .4 to .6" [1 to 1.5 cm] long, fascile of single, successive flowered inflorescence at the apex of the ramicaul and has minutely pubescent floral bracts.

Very similar to and often cited as a synonym of M lonchophyllus but differs in having raised dark purple spots on the inner surface of the sepals and petals and a bulbous apex to the lip. The tip is suborbicular with revolute margins above the middle with a minutely spiculate-verrucose surface. M lonchophyllus has glabrous sepals and the apex of the lip is convex and not bulbous thickened.
