EARLIER

Common Name The Rio Chingual Microchilus [A river in Succumbio province of Ecuador]

Flower Size .12" [3 mm]

Found in Succumibios province of Ecuador on steep forested ridges at elevations around 1000 meters as a miniature to small sized, warm to cool growing terrestrial with an erect, terete stem carrying laxly 3, obliquely elliptic, subacuminate, petiolate base leaves that blooms in the earlier winter on an erect, terminal pubescent, 18.28" [47.2 cm] long overall, peduncle 10.48" [26.2 cm] long, provided with 9, scattered to lax, sheathing bracts, rachis 8.44" [21 cm] long, densely many flowered inflorescence with ovate-lanceolate, acute, green, 2 to 3 times longer than the ovary floral bracts and carrying externally sparsely pubescent, green flowers.

"The general aspect of the inflorescence and shape of the floral parts of M. chingualensis is much like its Ecuadorian congener Microchilus puyoensis . However M. chin- gualensis differs from the latter in having longer .5 to .8" versus .4" (12.5 to 20 mm vs. 10 mm) floral bracts, flowers with narrower .04 versus .052 to .06" (1 vs. 1.3 to 1.5 mm) petals, a slightly longer .132" versus .12" (3.3 vs. 3 mm) spur, a narrower .076 to .08" versus .12 to .14" (1 .9 to 2 vs. 3 to 3.2 mm) epichile, and a longer .12 versus .088 to .096" (3.0 vs. 2.2-2.4 mm) column."
