Common Name The Tulameng Mountain Microchilus

Flower Size .12" [3 mm]

Found in Guyana at elevations around 675 to 915 meters as a large sized, warm growing terrestrial with an erect stem carrying 4 to 5, obliquely oblong to oblong -elliptic, drying green, subacuminate, petiolate base leaves that blooms in the summer on an immature on the type, erect, 6.64" [16.6 cm] long, peduncle about 3" [7.5 cm] long provided with 3, flushed purple sheathing bracts, rachis [9.1 cm] long, densely many flowered inflorescence with ovate rhombic, subacuminate, 3 veined, externally laxly pubescent, thinly papery, longer than the ovary floral bracts and carrying cream-maroon, externally lax pubescent flowers.

"Externally, this species resembles Microchilus fendleri from Venezuela in its robust habit and almost paleaceous floral bracts. However it is most closely related to Microchilus robustus , differing in having ovate-rhombic (not oblong to oblong-lanceolate) floral bracts, half as small flowers, and rhombic (not oblanceolate) petals."
