Common Name The Gaping Oncidium [refers to the large teeth of the callus]
Flower Size 1/2" [1.25 cm]
Found in southeastern Brazil and maybe Peru at elevations around 1000 meters as a miniature sized, cool to warm growing epiphyte with slightly compressed, round pseudobulbs, partially enveloped by 2 to 3, basal, dry, scarious sheaths and carrying a single, apical, leathery, oblong to linear-oblong, keeled dorsally, shortly conduplicate below into the base leaf that blooms in the winter on a basal, slender, erect, simple to few branched, many flowered inflorescence arising on a mature pseudobulb with well spaced flowers
CAUTION!!! This species is very similar to O edwallii and has been confused in some references. I follow Pabst here but I am not 100% sure that this is correct as I have not been able to see Cogniaux's or Lindley's type descritions or drawings.
