ODONTOGLOSSUM NOBILE, _Reichenbach fil. in Linnæa_, 22, 850.
Habitat in NEW GRANADA, Province of Pamplona, at the height of from 5000 to 6000 feet, _Funck and Schlim_.
PSEUDOBULBS _from 2 to 3 inches long, of an ovate form, glossy, and mottled with dark brown, usually bearing 2 lorate_ LEAVES, _which are from 6 inches to a foot long, narrowed at the base and sharp at the end, much shorter than the tall upright branched_ PANICLE, _which sometimes rises to the height of 3 feet, and bears from 6 to 60 membranous_ FLOWERS _of a peculiarly delicate texture_. BRACTS _very small_. SEPALS _ovate-oblong, apiculate, slightly waved at the edges, an inch long, white with streaks of rose-colour_. PETALS _similar in form and texture to the sepals, but broader and more curled at the edges, of the purest white_. LIP _inclining to fiddle-shape, pointed, but with the point invisible when looked at in front; towards the base are two short upright tubercles that pass forward into plates diverging from each other, and toothed in front. On either side are two pseudo-wings, irregularly indented, and, like the plates, of a beautiful gold colour, streaked with red. The rest of the lip is white, with the exception of a few irregular blotches of crimson, the number and size and disposition of which vary considerably in different individuals_. COLUMN _short, with short wedge-shaped_ WINGS, _a little indented at the edges_.
