valde coriacea, rigida,patentia,subtus densissime adpresso-pilosa, 

 adulta supra glabra. Inflorescentiae oppositifoliae, densissime 

 patenti-pilosae. Flores extus valdissime pilosi. Sepala lateralia 

 obliquissime oblonga, acuta, apice dorso valde carinato-incras- 

 sata, mentum saccatum formantia. Sepalum dorsale oblongum, 

 subacutum, valde concavum. Petala lineari-spathulata, falcata, 

 apice late rotundata. Labellum in circuitu spathulatum, triloba- 

 tum ; unguis conduplicatus ; lamina suborbicularis, prope basim 

 callis binis papillosis et prope apicem callo plus minusve dis- 

 tincto praedita; lobi laterales auriformes; lobus medius reni- 

 formis, retusus, apiculatus. Gynostemium clavatum, pubescens, 

 pede longiore donatum. 



Plant robust. Stem stout, entirely concealed by closely wTap- 

 ping leaf sheaths, which are very densely brown (or rusty) 

 appressed-pilose or velutinous, width of sheathed stem about 

 7 mm.; joints somewhat swollen. Leaves distichous, at intervals 

 of about 4 cm., ±15 cm. long, 1.75 cm. broad, narrowly lanceo- 

 late to linear-lanceolate, long acuminate, cuneately narrowed 

 to a clasping base, thick, coriaceous, rigid, densely appressed 

 brown pilose or velutinous on the lower surface, the older leaves 

 glabrous above (the immature leaves appressed pilose above and 

 beneath), the margins strongly revolute in the dried specimen. 

 Inflorescences ±10 cm. long, opposite the leaf bases, spreading, 

 decurved in course of development. Rachis very densely spread- 

 ing rusty pilose, more or less zigzag in development. Bracts up 

 to 1 cm. long, suborbicular when spread out, obtuse, concave, 

 spreading, reflexed in late development, densely spreading pilose 

 beneath. Perianth somewhat connivent. Sepals densely spreading 

 pilose without. Lateral sepals 6-6.5 mm. long, about as broad, 

 very obliquely oblong, acute, dorsally carinate-thickened at the 

 apex, the basal portion forming a deep saccate mentum. Dorsal
