Common Name The Frog Oncidium

Flower Size more than 1/2" [more than 1.25 cm]

Found in eastern Brazil at elevations around 1800 meters as an small sized, cool growing epiphyte with bifoliate, ribbed, flat conical to slim conical pseudobulbs subtended by several scarious bracts and carrying 2 to 3 leaf-bearing sheaths with suberect, thinly coriaceous, linear or linear-lanceolate, subacute leaves that blooms in the summer and fall to an erect, many branched, spreading, to 14" [35 cm] long, many flowered panicle with lanceolate, acute bracts and carrying small, showy flowers.

This species, Onc lofgreni and O hookeri are all very similar and according to Brazilians sources are only separated if the area of collection is known as differences are very small and are mostly vegatative. Newer references refer them all as synonyms of Oncidium raniferum but I have left them and their synonyms separate for now.
