Common Name The Gonzalez Family Pleurothallis [Costa Rican Consevationists at the Bosque de Paz Biological Preserve where the species was found Current]

Flower Size .96" [2.4 cm]

Found in Alajuela province of in Costa Rica in lower montane rain forest along the Caribbean slopes of the Cordillera Volcánica Central at elevations around 1500 to 1600 meters as a medium sized, cool growing, caespitose epiphtye with a terete, slender, yellowish green ramicaul provided with 2, tubular, short, truncate sheaths at the base and a longer, tubular, tightly adpressed, broadly obtuse sheath below the middle and carrying a single, horizontal at the apex of the ramicaul, becoming subpendent with age, thinly coriaceous, flexible, sessile, ovate, acuminate, deeply cordatte below into the base leaf that blooms in the later summer on a short, arising through a prostrate, brown, evanescent spathe, single, rarely 2 flowered inflorescence .

"Pleurothallis gonzaleziorum differs from P. cardiothallis by its distinctly triangular lip (vs. peltate), glabrous on the underside (vs. papillose), with the apical margins non involute. The lip is more similar to that of P. oncoglossa, but in the latter species the lip apex is thickened into a conical callus, bent back as a hook, whereas in P. gonzaleziorum it is straight and thin. By its triangular lip it is also similar to P. scotinantha, which however has much smaller, concolorous dark purple flowers." Pupulin etal 2021
