38 MALAXIDEZE. PLEUROTHALLEZ. 
cuneatis membranaceis imbricatis, sepalis lateralibus ovatis dorso acutis, 
labello ventricoso (undulato ?) indiyiso emarginato. 
Hab. in Napalia, Wallich. (hab. s. sp. comm. cel. Lambert.) 
Articuli rhizomatis 12 unciam longi. Folia circiter 3-uncialia. Columna 
teres antice tumida. Dorsum clinandrii erectum, rostellum ovatum 
porrectum. 
I know this very remarkable species by specimens given me several 
years since by Mr. Lambert. It came to England with some of Dr. Wal- 
lich’s earliest Nipal collections. Its imbricated unilateral recurved spikes 
characterize it well, and distinguish it from P. articulata which besides 
has the joints of the rhizoma twice as long, and the bractez of a different” 
figure.
