"Closely related to Porroglossum amethystinum but P olivaceum is distinguished by the light tan color of the flowers with darker veins, obtusely angled free margins of the dorsal sepal and transverse apices of the lateral sepals. The tails of the lateral sepals usually emerge about equidistant between points of junction with the dorsal sepal and the other lateral sepal where a deep, acute mentum is formed. Occasionally a non-resupinate flower is produced. The blade of the lip has a tall, longitudinal callus." Luer 1991
