Rossioglossum grande, also known as Odontoglossum grande Lindl. is a plant in the family Orchidaceae, native to South and Central America. It is described as follows in Paxton’s Magazine of Botany, under the common name of magnificent tooth-tongue:
From five to six inches is the usual breadth of the flowers from the tip of each petal; the sepals are mottled and barred like the back of a tiger; the brown of the petals is of that rich, smooth, shining character, as to appear an artificial preparation; the lip resembles the upper portion of a cockle-shell in figure, is most delicately stained, and when held to a lamp exhibits a glittering transparency of texture for which other Orchidaceous flowers are so remarkable; while, perhaps, the most pleasing part of all is the splendidly mottled tubercles at the base of the lip, which, viewed from the side, or almost any position, are
in the highest degree beautiful, though, as if to attest the fugitiveness of physical beauty, these are the first to fade.
