Common Name or Meaning The Tuberculate Brachionidium [refers to the callus of the lip]

Flower Size 1" [2.5 cm]

Found in Venezuela, Colombia, Ecuador, Bolivia and northern Brazil at elevations around 2500 to 2900 meters as a mini-miniature sized, cold growing mostly terrestrial orchid in leaf humus or low epiphyte with an ascending rhizome giving rise to ramicauls enveloped by 3 long-mucronate sheaths that are tuberculate on the lower margins and carrying a single, apical, suberect, coriaceous, more or less purple suffused, broadly elliptical, prominently 7 to 11 veined, subacute to obtuse, broadly cuneate below into the petiolate base leaf that blooms in the spring and summer on an erect, arising from near the apex of the ramicaul with a bract near the middle, .4 to 1.2" [1.1 to 3 cm] long, solitary flowered inflorescence with an inflated, long-mucronate, longer than the ovary floral bract and carries a non-resupinate flower that can be yellow to light to dark purple.

"Characterized by the stout rhizome that usually grows more or less erect terrestrially. The rhizome is covered by a series of mucronate sheaths that are more or less tuberculate or fimbriate in their lower margins. The solitary purple flower with aucminate seplas and petals is held just above the leaf. The petals are microscopically but densely ciliate. The broadly cordate lip is furnished with an elevated but flat, minutely pubescent callus channeled on the front surface into a glenion." Luer 1995
