Common Name The Flower Spring Oncidium [refers to the allusion of the inflorescence to a waterfall]

Flower Size 1.5 to 2.5" [3.8 to 6.4 cm]

Found from Panama, Colombia and Ecuador at elevations of 100 to 1000 meters as a large sized, hot to warm growing epiphyte or sometimes terrestrial orchid with ovate, ribbed, laterally compressed, ancipitous pseudobulbs enveloped basally by several leaf-bearing sheaths and carrying 2 apical, linear-lanceolate, conduplicate below into the base leaves and blooms in the winter and spring on an erect to arching, 24" to 48" [60 to 120 cm] long raceme with several short basal branches of 2 to 3 flowers each of several to many, showy, waxy, very fragrant flowers on the rest.

CAUTION The pictured orchid is Oncidium anthocrene var powellii so it may be Oncidium powellii instead of O anthocrene, I need more information to make a correct determination.
