Common Name The Sphere Carrying Oncidium [refers-erroneously - to the pseudobulbs]
Flower Size 1 1/2" [3.75 cm]
Found from Costa Rica, Panama, Venezuela, Colombia, Ecuador and Peru as a small sized, hot to cool growing epiphyte in cloudforests at elevations of 400 to 2400 meters with widely spaced groups of small plantlets arising on the terete, smooth, green rhizome, branching and rebranching to form tangled mats or long twining, vine-like plants giving rise to suborbicular-oblong, compressed pseudobulbs enveloped basally by 1 or 2 leaf-bearing sheaths and carrying a single, apical, fleshy, suberect, oblong, obtuse leaf that blooms at most any time of the year on a single flowered, dull purple, 4" [10 cm] long, inflorescence arising on mature pseudobulbs from the leaf sheaths and directly from the rootlike rhizome.
DNA testing has shown a close relationship between the section Serpentia [four species O globuliferum, O sancti-Pauli, O serpens and O harlingii] and Otoglossum but there are obvious visual plant and flower differences which I feel help us separate this group better and easier.
