Deep shade Cold

Common Name The Ovate Microchilus [refers to the leaves? Lip apex? or Lip lateral lobes? or the 2 ovate calli?]

Flower Size .12" [3 mm]

Found in Colombia, Venezuela, Peru and Bolivia in cool, wet cloud forests at elevations around 2500 meters as a medium sized [in flower], cold growing terrestrial with a decumbent, becoming erect, terete, pubescent above the leaves, glabrous below stem carrying 5, spiraling up the stem, well spaced, ovate, acute, velvety green above, smooth somewhat greyish green beneath, petiolate base leaves that blooms on an erect, terminal, racemose, long pedunculate, pubescent, to 8" [20 cm] long, rachis pubescent, initially club-like elongating and becoming cylindric with age, successively several, many flowered inflorescence with ovate, obtuse, pubescent, longer than the ovary floral bracts and carrying small, tubular, spirally arranged flowers

CAUTION I have no way of verifying this determination, Kew says the orchid is from Colombia Peru and Bolivia, Dunsterville says it is from Colombia, Venezuela and Peru. Ormerod separated the Peruvian species under the synonum M peytoniorum. Then there is Foldats with another totally different species with a lip with 2 ovate calli on the trilobed lip with short ovate lateral lobes. I feel that the Dunsterville and the later Szlachetko & Kolanowski drawings and description may apply to another Microchilus. I have presented drawings of all the concepts above. More research is nessesary. Please use with caution!!!!
