Common Name The Splendid Oncidium

Flower Size 2.1" [5.3 cm]

Found in Sao Paulo, Brazil as a medium sized, cool to warm growing epiphyte with ovoid, elongate, slightly compressed and rugose, 4" [10 cm] psuedobulbs that have 2 to 3 apical, lanceolate, coriaceous yet flexible, curved 8" [20 cm] leaves. The basal panicle is stiff, usually pendant, branched, lax and 2 to 5' [60 to 150 cm] long and carrying many non-fragrant, variable sized flowers that arise in the fall and winter.

Often given as a synopnym and most likely is of the variable flowered O varicosum but differs in the much larger flower, the callus consisting of three low parellell basal ridges terminating in a single, very large, bilaterally compressed, rhomboid tooth without any ancilliary knobs. The flower is also inflexed at a 90 degree angle relative to the base of the lip forming a shelf-like platform and the lateral sepals are solid brown of the same color as the deep red brown irregular blotch surrounding the crest. They are almost always found in conjunction with O varicosum often on the same tree.
