Finding
This plant matches the original description in Orquideologia XIV No. 2, Feb 1981. The description as "laxly few flowered" refers to the number and arrangement of flowers on a single arrangement. This species flowers in profusion, but looking at the individual inflorescences, they are 4-5 flowered, matching Luer's drawing. The petals are elongate with a single midvein and the shape and structure of the leaf (broadly elliptic, ribbed, and distinctly petiolate) also match the description. There are some differences noted in this plant's leaf structure compared to the drawing of P. notabilis.
