LATE 
Common Name The Two Conic Spur Microchilus
Flower Size .2" [5 mm]
Found in Costa Rica in primary forests at elevations around 1600 to 1700 meters as a small sized, cool growing terrestrial with several, along the bottom half of the stem, elliptic, short acuminate, gradually narrowing below into the petiolate base leaves that blooms in the late spring and fall on a terminal, erect, 4 to 8" [10 to 20 cm] long, successively several flowered inflorescence with tubular bracts and lanceolate, to elliptic-lanceolate, crisped puberulent, shorter than the ovary floral bracts.
"This species, is distinctive in the large flower and the presence of two conic spurs. In spite of intensive collecting in Monteverde area by Bello, Dryer, Haber and others, I have seen only two collections, suggesting that the species is infrequent. Further, the fleshy flowers are badly damaged by pressing, so that only the type collection has more or less useable flowers." Dressler 1993
"Similar to M parvilabrum but its laxly inflorescence is quite short, few flowered, the leaves are relatively small and the flower segments are smaller." Szlachetko & Kolanowska 2017
