Common Name The Star-Carrying Oncidium

Flower Size 2" [5 cm]

Found in Guerrero, Jalisco and Michoacan states in Mexico and northern Guatemala at elevations of 1400 to 1900 meters as a medium sized, cool growing epiphyte with a ovoid-ellipsoid, compressed psuedobulbs partially enveloped basally by several, distichous, imbricating, leaf-bearing sheaths and carrying 2 apical, elliptic-oblong, subacute, coriaceous, slightly conduplicate towards the base leaves that blooms in the winter on an axillary, erect to arching, 34" to 80" [80 to 200 cm] long, several branched panicle with large, showy, stellate flowers.

Often cited as a synonym of O hastatum but I can see several differences, I await further references to combine them.
