ORCHIDACE^ 



paucae, fibrosae, ramosae, rigidae, crassae. Pseudobulbus fusi- 

 formi-cylindraceus vel late pyriformis, monophyllus, in visu ru- 

 gosus, fibris vaginarum cinctus. Folium lineare vel oblongo- 

 ellipticum, ad apicem basimque sensim angustatum, complicato- 

 mucronatum, valdissime plicatum, rigidum, coriaceum. Petio- 

 lus cylindraceus, crassus. Inflorescentia heterantha. Pedunculus 

 pseudobulbo approximatus, e basi decumbenti subereetus vel 

 arcuatus, omnino glaber, vaginis nonnullis imbricantibus basim 

 versus. Rachis arcuata vel nutans, bracteis imbricantibus una 

 vel duabus sustenta. Racemus laxus, distichus. Bracteae inflo- 

 rescentiae variabiles, in visu convolutae, ovarium pedicellatum 

 amplectentes et superantes, oblongo-ovatae, rigidae, nervosae. 

 Perianthium subcrassum. Sepala quinquenervia. Sepala lateralia 

 lanceolato-oblonga, acuta, dorso carinata, leviter cymbiformia. 

 Sepalum dorsale simile. Petala anguste elliptica, subacuta aut 

 obtusa aut subtruncata, basi trinervia. Labellum in positu natu- 

 rali fere ad medium convolutum, expansum late lanceolatum, 

 parte anteriore incrassata obtusa; lamina prope basim leviter 

 reflexa, marginibus utrisque circa parte tertia ab apice subemar- 

 ginatis; carinae tres humiles simplices e basi ad apicem decur- 

 runt. Gynostemium breve, basi labelli circumdatum, ala magna 

 apicali truncata praeditum. 



Rhizome stout, woody, closely invested by imbricating 

 sheaths that become fibrous. Roots up to 2 mm. thick, appar- 

 ently few, stout, fibrous, flexuous, freely branched, rigid, gla- 

 brous. Pseudobulb ±2.5 cm. long, fusiform-cylindric to broadly 

 pyriform, monophyllous, more or less oblique, rugose in the 

 dried plant, invested by the fibrous remnants of sheaths. Leaf 

 ±21.4 cm. long, 2.14 cm. broad, linear, oblong-linear or oblong- 

 elliptic, gradually narrowed to a distinct complicate-mucronate 

 apex, similarly narrowed to a complicate base, very strongly
