Oncidium leucomelas (Rchb. f.) Dressler & N.H. Williams 2003 SECTION Stellata Photo by Jesus Cid

Common Name The Black White Oncidium [refers to the color of the type not the varieties]

Flower Size 2.5" [6.25 cm]

Found in Chiapas Mexico, Guatemala, El Salvador, Honduras and Costa Rica in montane rainforests, pine/oak-Liquidambar and secondary forests at elevations of 1250 to 1800 meters as a medium sized, cool growing epiphyte with ovate to oblong-ovate, compressed, sulcate pseudobulbs enveloped basally by a few leaf-bearing sheaths and carrying 2 apical, lanceolate to narrowly elliptic, subcoriaceous, obtuse, conduplicate towards the base leaf that blooms in the spring on a basal, through the leaf sheath, racemose to paniculate, green with purple spots, erect-arcuate, 9.6" to 11.2" [24 to 28 cm] long, lax, successively few, 6 to 20 flowered inflorescence with triangular, scarious, acute floral bracts

This species is said to be a synonym of Oncidium laeve. I leave them separate because a visual of the photos shows several differences if the photos are ID'ed correctly, anyone?
