"Similar to P phyllocardioides but differs in the by the narrowly ovate leaf, rounded below into the cordate base leaf. The flowers are purple red with the sepals longer and the petals almost the same in length. The lip is similar to P phyllocardioides." Luer 2003

"Characterized by narrowly ovate leaves that are rounded to cuneate at the base. It is similar to P isthmica a larger and more robust species with a longer lip. The small flower of P upanoensis is distinguished mostly by the expanded, straight petals that are as long as the synsepal and twice as long as the lip." Luer 2005
