slightly beyond the middle, shiny, glandular, much narrower 

 than the membranous part; not gibbous at base. Lateral 

 appendages of column very wide, with sinuous basal lobe, 

 shorter than anther and much shorter than rostellum. 

 Hostellum higher than anther, caudicle rather long and 

 slender, attached to a large ovate-lanceolate gland. 



var. triglochin (Lake Chockerup). 



Lateral petals 2 "5 mm. long; sepals 3 mm. long; labellum 

 oval or broadly elliptical, 25 mm. long. 



The leaf of this species is stated by Bentham to have a 

 long lamina. An examination of a large number of specimens 

 in the field and herbarium indicate that the leaf-lamina is 

 almost invariably short as in the case of P. cyphochilum.
