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 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.
