Common Name The Cerro Montezuma Pleurothallis [A mountain in Costa Rica]

Flower Size .2" [5mm]

Found only in Costa Rica at elevations around 600 meters as a small sized, hot growing epiphyte with an erect, slender ramicaul enveloped by 2 to 3, tubular, acuminate sheaths and carrying a single, apical, erect, coriaceous, elliptic, acute, cuneate below into the elongate, channeled, petiolate base leaf that blooms in the summer on a .4 to .6" [1 to 1.5 cm] long, successively 2 flowered inflorescence arising from low on the ramicaul.

This species is very similar to P fulgens but this one differs in having a verrucose and denticulate lip above the middle and has no lateral lobes. The column foot is concave between a pair of calli as seen in Zootrophion. This species is also similar to P guanacastensis but differs in the tall carinate, apiculate sepals amd the apiculate apex of the lip and a pair of calli flanking the cavity on the column foot.

P montezumae is in a group of closely related species which include P endotrachys, P deuterodunstervillei, P pfavii, P deuteroremotiflora, P spectabilis, P juddii, P fulgens, and P guanacastensis.
