coriaceum. Scapus pseudobulbo approximatus, in visu folio bre- 

 vior, vaginis nonnullis infundibuliformibus late patentibus prae- 

 ditus. Racemiis laxiflorus. Bracteae inflorescentiae anguste del- 

 toideae, acuminatae. Flores perparvi, in sicco pellucidi. Sepala 

 lateralia lanceolato-attenuata apicibus longis caudatis, mentum 

 saccatum formantia. Sepalum dorsale lineari-lanceolatum, atten- 

 uatum, concavum. Petala minuta, linearia, acuta vel subacuta. 

 Labellum perparvum, in positu naturali fere in medio decurvum, 

 parte inferiore membranacea lateribus erecto-conduplicatis, parte 

 anteriore ovato-elliptica acuta vel subobtusa; lamina expansa 

 in circuitu anguste deltoidea. Gynostemium minutissimum, bra- 

 chiis binis anguste triangularibus acuminatis instructum. Pes 

 parte inferiore incrassatus, apice unciformis. 



Plant slender. Rhizome creeping, woody, invested by the 

 remains of sheaths which have become lanate fibrous. Roots 

 numerous, fibrous, flexuous, branched, longitudinally sulcate, 

 about .8 mm. thick. Pseudobulbs very small and concealed by 

 marcescent sheaths, about 3.5 mm. high, thick-cylindric, deeply 

 rugose in the dried specimen, monophyllous, about 1.3 cm. dis- 

 tant. Leaf about 13 cm. long, 1.8 cm. broad, narrowly oblong, 

 acute and indistinctly complicate in the dried specimen, gradu- 

 ally narrowed to the petiole, coriaceous, many-nerved with the 

 mid-nerve somewhat sulcate above and conspicuously carinate 

 beneath, margins revolute in the dried plant. Petiole about 4 cm. 

 long, sulcate. Scape approximate to the pseudobulb, enwrapped 

 with the petiole in one or more marcescent sheaths, suberect or 

 gently arcuate, apparently shorter than the leaf but broken off, 

 provided with four or five scarious widely spreading infundibu- 

 liform sheaths which are imbricating below and remote above. 

 Raceme loosely flowered. Bracts of the inflorescence about 

 3.5 mm. long, narrowly deltoid, acuminate, concave, surpassing
