"Though Microchilus procerus was first recorded from Venezuela by Knuth (1927), this and later records refer to different taxa (e.g. M. campanulatus Ormerod and M. fendleri Ormerod). Thus the specimen cited above from Venezuela represents a new record for that country." Ormerod 2009

"M procera is easily distinguished by the robust plant, and the form of the lip. especially the undulation of the hypochile margins as well as the petal margins. Although it is worthy to note that the lip and petal undulation is not well notided in herbaruim specimens." Szlachetko & Kolanowska 2017
