Found in Minas Gerais state of Brazil at elevations around 670 meters as a small to medium sized, warm growing epiphyte with ascending to erect ramicauls enveloped by 7 to 8 tubular sheaths and carrying a single, apcial, erect, thickly coriaceous, elliptical, obtuse to rounded, cuneate below into the subpetiolate base leaf that blooms in the spring on a fascile of simultaneous single flowers arising at the apex of the ramicaul and has inflated, sparsely pubescent-spiculate, as long as just short of the length of the pedicel floral bracts.

"The habit and flower of M. pulvinatus is similar to Myoxanthus congestus but mainly distinguished by its column apex frequently bidentate on both sides and generally apiculate lip vs. with an acute tooth on both sides and apex acute to obtuse."
