Liparis monophylla Ames sp.nov. Herba epiphytica. Pseudo- 
bulbi approximati, 3-10 cm. longi, circa 1 cm. in diametro prope 
basim pseudobulborum, 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 em. 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, 
arcuatum. 
Liparis monophylla is similar in habit to L. serrulata Schltr. 
It is separable from L. parviflora 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.
