"In habit this species resembles P xiphuzusa but the flowers are larger with ciliate-pubescent sepals within and with the latrerals acute and free from below the middle. The petals are broadly oblong. The lip and column are also similar to P laevigata with the subquadrate lip that is bicallous near the middle." Luer 2000
