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_. This lovely plant was discovered in the year 1847 by MM. Funck and Schlim when on a botanical mission to New Granada, in the service of M. Linden. According to its discoverers, it is not unfrequently met with in the provinces of Pamplona and Ocaña, at an elevation above the sea-level of about 5000 feet, inhabiting the oak forests which--where the climate is mild--clothe the eastern slopes of the glorious Cordillera. _O. Pescatorei_ flowered with M. Linden for the first time in 1851, and attracted, as well it might, universal admiration. Nothing indeed, even in the beautiful family to which it belongs, can surpass the delicacy of its blossoms, with their charming mixture of rose and white, relieved by a few deep-crimson stains scattered irregularly over the lip. Its habit too is good, and its stately panicle of flowers well-proportioned to the size of the bulbs and leaves. It blooms abundantly in the spring months, and its blossoms continue at least six weeks in perfection. We need not wonder that a plant with such a rare combination of good qualities should have been selected by M. Linden to do honour to his patron the late M. Pescatore, after whom he named it, and in whose sumptuous work ('Pescatorea') it forms the first plate.
