Common Name The Tunqui Mayo Microchilus [a Town near where the type was collected]

Flower Size .12" [3 mm]

Found in Cusco department of Peru in secondary forests at elevations around 1870 meters as a giant sized, cool growing terrestrial with an erect, terete stem carrying 7, obliquely oblong to oblong-elliptic, subacuminate, petiolate base leaves that blooms in the spring on an erect, terminal, pubescent, 6.64" [44.8 cm] long, peduncle about 3" [28. 7 cm] long provided with 10, sheathing bracts, rachis [36.1 cm] long, subdensely many flowered inflorescence with ovate-lanceolate, acute, longer than the ovary floral bracts and carrying white, externally pubescent flowers.

"This species resembles its Peruvian congener Microchilus atalayae in being a large stout plant with numerous, relatively small flowers. However M. tunquianus differs in having oblong, biveined (vs. ligulate-spatulate, one veined) petals, an oblong-subpandurate (vs. ovate-lanceolate) labellum hypochile and shorter .108 versus .16" (2.7 vs. 4 mm) spur."
