Trichocentrum pfavii is native to Costa Rica and Panama. This orchid was discovered in the Chiriquí Province in western Panama. Since then, it has been found in tropical rainforest at an altitude of 600-1300 m, on the slopes towards the Pacific in south-eastern Costa Rica, on sites near the border with the Chiriquí Province in Panama.
It is a miniature sized, warm to hot growing epiphyte, which reaching a height of 5-8 cm, with a minute pseudobulb carrying a single, apical, fleshy, elliptic-oblong, subacute, 5-8 cm long and 1.5-3.0 cm wide leaf that is basally conduplicate.
Trichocentrum pfavii blooms in the fall to early spring on a lateral, suberect, to 5 cm long, single to rarely 2 flowered inflorescence enveloped by bracts that is shorter than the leaves. The white flowers are 2.0-2.5 cm in diameter, and the lower halves of the petals of both whorls are marked with red spots of irregular shape. The outer whorls are loose and not dissimilar to the dorsal leaf, which is concave, elliptical to egg-shaped, blunt ended. The lateral outer petals are elliptical to the oval-lanceolate, have slightly curved rounded tops. The inner whorls have a shape similar to the side outer petals, but are slightly larger. The lip is 2 cm long and 1.3-1.5 cm wide across the spread out middle plot. The base of the lip goes into a short, wide spur. Above the spur is a long, narrow claw extending up to the base of a wide, rounded plot. At the base of the claw there is a pair of tiny, uder-like processes, and the edge of the middle plot is wavy or curled and has a deep indentation in the middle. The thickening is simple and has 2 fleshy combs. The short rod is 0.5-0.7 cm long and a pair of pointed, unfolded wings with the shape of axes with irregularly serrated edges. The anther chamber has a spherical shape and is quite densely covered with small, verrucous protrusions.
