Maxillaria eburnea Lindley 1840 Photo courtesy of Eric Hunt, plant grown by Andy's Orchids

Common Name The White-Flowered Maxillaria

Flower Size to 4" [to 10 cm]

Found rarely in Guyana at elevations of 1500 to 1800 meters as a small to just medium sized, cool to cold growing epiphyte with ellipsoid, small pseudobulbs with small papery bracts and carrying a single, apical, oblong-elliptic to elliptic, abruptly acuminate, petiolate base leaf that blooms on an elongate, slender, erect, to 7.8" [19.5 cm] long, single flowered inflorescence with lanceoalte, acumiante, longer than the ovary floral bracts.

This is a single, large flowered orchid has not been recollected since it's discovery in 1840 and is often erroniously refered to as a synonym of M grandiflora but it differs significantly in the lip, this species has a much less ruffled, unlobed lip apex and a central callus with ancilliary calli on either side.

Most likely according to Christenson the orchid photo graphed above cannot be the real M eburnea, according to his research M eburnea has a pure white flower and pseudobulbs without foliaceous bracts
