Common Name The Grass Leafed Oncidium

Flower Size 3/4" [2 cm]

A small sized, warm to cool growing, terrestrial species from dry pine forests in south western Mexico, Guatemala and Honduras at elevations of 1100 to 2500 meters with ovoid to elliptic, compressed, sulcate, pale green pseudobulb with 4 to 6 basal, subcoriaceous sheaths with the uppermost being leaf-bearing and 2 to 3 apical, narrowly linear-elliptic, deciduous leaves that blooms on a racemose, sometimes branched, 12 to 30 " [30 to 75 cm] long, erect to arcuate inflorescence arising on a mature pseudobulb with triangular, scarious bracts that has 7 to 15, successively opening, showy flowers which open 2 to 5 at a time all placed at the apex of the inflorescence occuring in the summer through spring. This species is considered by many to be O. brachyandrum but others separate this as a species because it is terrestrial, has succesive flowers and etal. and the other is epiphytic and has simultaneously opening flowers.
