"This species is superficially similar to P lojae but P venulosa is distinguished by the narrower leaves and a shorter inflorescecnce. The veins of the sepals are conspicuously thickened or subcarinate. The sigle vein of the petal is also prominently thickened. The lip is thick with erect, rounded margins below the middle with intramural calli near the middle and a pair of verrucose calli in the disc below the middle." Luer 2004
