Herba epiphytica, robusta, magna. Pseudobulbus 
ovoideus vel cylindraceo-pyriformis, unifoliatus, Folium 
magnum, petiolatum; lamina oblonga vel elliptico- 
oblonga, plusminusve acuta, basi cuneata; petiolus elon- 
gatus, conduplicatus. Inflorescentia perbrevis, pedunculo 
cum ovario vaginis distichis ovatis imbricatis omnino 
tecto. Flos pro planta parvus. Sepala basi concava, la- 
teribus revolutis. Sepalum = dorsale oblongo-ovatum, 
abrupte complicato-acutum. Sepala lateralia similia, ob- 
liqua. Petala obovato-oblonga, subacuta, quam sepala 
paulo breviora. Labellum super medium trilobatum, ex- 
pansum in circuitu late ellipticum; lobi laterales angusti, 
apice libero rotundato; lobus medius suborbicularis, in- 
crassatus, verrucosus, supra recurvus; discus parte in-

Plant large, robust, epiphytic. Roots fibrous, glab- 
rous, elongate. Pseudobulb apparently ovoid or cylin- 
dric-pyriform (imperfect in the specimen), plurisulcate 
when dry, unifoliate, about 5 cm. long, apparently rather 
compressed, surrounded by the fibres of sheaths. Leaf 
large, petioled; lamina oblong or elliptic-oblong, acute 
or subacute, about 50.8 em. long and 5.8 cm. wide, cu- 
neate below, coriaceous, shining above and dull beneath, 
with the mid-nerve suleate above and strongly carinate 
beneath; petiole elongate, stout, conduplicate or deeply 
channelled, about 17.8 em. long. Inflorescence (separated 
in my specimen) very short, 1-flowered; peduncle with 
pedicellate ovary about 2.9 em. long, entirely concealed 
by six broadly ovate distichous imbricating sheaths.
