Common Name Soto's Myoxanthus [Mexican Botanist murdered in 2009]

Flower Size .24" [6 mm]

Found in Costa Rica on the Caribbean slopes of the Central Volcanic Cordillera in secondary vegetation along the river, premontane wet forest at elevations around 800 meters as a large sized, warm growing epiphyte with slender, cylindric ramicauls enveloped by 2 to 6 tubular, pubescent sheaths and carrying a single, apical, erect, coriaceous, elliptic, conduplicate, acute, narrowly cuneate below into the subpetiolate base leaf that blooms in the spring and summer on a fascile of single successive flowers arising through a spathe, peduncle .08" [2 mm] .16 to .24" [4 to 6 mm] long, few flowered inflorescence with tubular, ovate, acute, conduplicate, pubescent, half as long as the pedicel.

" Myoxanthus sotoanum is similar to Myoxanthus scandens Ames, from which it differs in the linear leaves (vs. elliptic), brownish-yellowish flowers (vs. dark purple), the yellow petals and lip (vs. purple striped), oblong, obtuse, subfalcate lateral lobes of lip (vs. triangular, acute, erect) with two keels extending nearly to the middle of the lip (vs. extending to the apex of the lip), and the triangular, acute teeth (vs. acicular, acuminate) that flank the stigmatic cavity. It also generally occurs at lower elevations." Bogarin & Fernandez 2010
