Pseudobulbs produced from a stout creeping rhizome, these are some four inches in length, compressed, bearing a single oblong, obtuse leaf on the summit, which is thick and leathery in texture, very glaucous, and from three to six inches in length. Peduncle erect, about as long as the leaf, issuing from a small compressed sheath on the top of the pseudobulb, and bearing a single large flower, which is delicately fragrant. Flowers three to four inches across; sepals and petals nearly equal, lanceolate in outline, and obtuse of a soft pale green hue; lip cordate, acute, waved at the edges, white, marked in the throat in some instances with lines of pinkish lilac. Column short and stout.

This is one of the old Orchids in English gardens, having been first introduced by Hartweg from Xalapa upwards of fifty years ago, and subsequently it was found in Guatemala by Mr. Skinner growing upon oak trees in company with other Orchids. It is a plant which has never become popular with the majority of English Orchid-growers, probably through lack of colour in its flowers, but it has frequently been found to exist in collections where it had never been known to bloom, and this, probably, more through neglect than from any other cause ; indeed, we flower the plant annually, and therefore cannot accept the dictum that it is difficult to bloom, provided the plant is kept in good health and is sufficiently strong to produce flowers. There is, moreover, a reason why the growth of this plant should be encouraged, flowering as it does in the months of February and March : it becomes an excellent subject for cross breeding, and for those having any enthusiasm on this subject, should be seized upon with avidity...
Native to Guatemala and Mexico.
I saw this plant at the SCOS show in 2015.
