Flower Size

Found in brazil and Paraguay along roadsides at elevations around 1000 to 1280 meters as a medium sized, cool growing terrestrial with a terete rhizome giving rise to an erect, terete stem carrying 4, obliquely ovate-elliptic, subacuminate, petiolate base leaves that blooms in the summer on an erect, terminal, pubescent, 14.2" [36 cm] long overall, peduncle 8.4" [21 cm] long, provided with a few scattered, acute sheathing bracts, rachis 6" [15 cm] long, many flowered inflorescence with ovate-lanceolate, acute, glandular, as long as the ovary floral bracts and carrying externally sparsely glandular flowers.

"Similar to both M trianae and M hughjonesii with the lip form but the sepals of M arevaloi are soarsely glandular and in the other 2 species they are pubescent. M hughjonesii differs as well in the broadly elliptic hypochiole of the lip while M arevaloi and Mtrianae it is more or less pandurate, but only M arevaloi has triangular elliptic lobes near the middle. The most unique asset of M arevaloi is the keel that runs along the midvein of the epichile.
