Common Name or Meaning The Tall Rising Pleurothallis

Flower Size 2" [5 cm]

Found in Antioquia and Tolima departments of Colombia and Ecuador in virgin forests at elevations around 1600 to 1900 meters as a large sized, cool growing, densely caespitose epiphyte or terrestrial in rich shaded humus with stout, erect ramicauls enveloped basally by a purple spotted, tubular sheath below the middle and 2 at the base carrying an apical, single, erect, thickly coriaceous, elliptical-ovate, subacute, sessile, gradually narrowing below into he cuneate base leaf that blooms in the winter and spring on a suberect to arching, arising through a basal spathe, loose, subsecund, 20 to 24" [50 to 60 cm] long, simultaneously several flowered, racemose inflorescence and has infundibular, acute, shorter than the pedicel floral bracts.

"This gigantic species one of the largest of all racemose species, occurs in the Central Cordillera of Colombia where it is infrequently encountered. It is found growing terrestrially in rich, shaded humus of virgin forests at a moderate altitude less than 2000 meters above sa level. Up to ten immense flowers with non-caudate sepals 2" [five centimeters] long are produced simultaneously on a stout, arching inflorescence. The protruding, cylindrical lip is nearly as long as the sepals. From a shallowly concave basal third, the margins of the lip recurve to form a long, straight, narrow tube." Luer 1994
