Liparis monophylla^/we* sp. nov. Herba epiphytica.Pseudo- 

 bulbi approximati, 3-10 cm. longi, circa 1 cm. in diametro prope 

 basim pseudobulbormn, juniores vaginis foliaceis inclusi, com- 

 planati, monophylli. Folium subcoriaceum, variabile, 1.5-4.5 dm. 

 longum, usque ad 7 cm. latum, prominenter nervosum, petiola- 

 tum; lamina elliptico-oblonga, acuta, utrinque attenuata, quam 

 pedunculus longior. Petiolus latus, circa 3 cm. longus. Bracteae 

 inflorescentiae ±6 mm. longae, lineares, scariosae, acutae, in sicco 

 albidae, pedicellum aequantes vel excedentes. Pedunculus infra 

 racemum paucibracteatus, brevis, cum racemo 14-22 cm. longus. 

 Flores mediocres, numerosi, in racemo denso cylindraceo spicato 

 dispositi. Racemus ±1.5 dm. longus, circa 1 cm. in diametro, 

 erectus, floribus approximatis. Sepala lateralia oblonga, 3.5 mm. 

 longa, utrinque angustata, subacuta, trinervia. Sepalum dorsale 

 simile. Petala 3.5 mm. longa, linearia, obtusa, uninervia. Label- 

 lum crassum, 3 mm. longum, 1.5 mm. latum prope medium, sub- 

 quadratum, truncatum, obtuse apiculatum, parte basali gynoste- 

 mio subparallela, parte apicali reflexa. Callus prope columnam 

 in disco labelli, minutus. Gynostemium circa 2 mm. longum,

Liparis monophylla is similar in habit to L. serrulata Schltr. 

 It is separable from L. parvifloj^a Lindl. by the form of the label- 

 lum and by the monophyllous pseudobulbs. 



In the material examined the flower shoot was without excep- 

 tion much shorter than the leaf, even in fruiting specimens.
