Flower Size

Found in Valle de Cauca department of Colombia in primary forests at elevations around 800 meters as a large sized, warm growing, caespitose presumably epiphytic orchid with stout, erect, very long ramicauls with a close, tubular sheath near the middle and anither at the base and carrying a single, apical, horizontal, coriaceou, ovate, acute, slightly acuminate, cordate below into the sessile base leaf that blooms on a short, arising through a 1" [2 .5 cm] long spathe, successively single, few flowered inflorescence with much shorter than the pedicel floral bracts.

Allied to the Ecuadorian P gargantua and only found once dso little infloramation is available. Distinguished by the sepals that are puberulent externally, the sepals of all others in the section are glabrous. Also distinctive is the tip of the petals being described as mucronate. Also differing from all others in the suborbicularlip, apparently not convex and densely transversly verrucose-rugose." Luer 2005

The other giant leafed relatives are P gargantua, P imperialis and P teaguei all of Section Macrophyllae-Fasciclatae and P colossus of Section Macrophyllae-Racemosae.
