 D. angiistifoliiim RiDL. 



From D. panduratiim SCHLTR. it differs by the longer pedicels conspi- 

 cuoLisly surpassing the bracts, the lip not being constricted in the middle, 

 the stelidia at least equalling the clinandrium ; from D. Gravenhorstii ].].S. 

 in the more acute leaves, the form of the petals, a very différent Hp, blunt 

 anther; from D, taeniophyllum J. J. S., which is a smailer plant, by the 

 broader leaves, differently coloured flowers, the form of sepals, petals and 

 lip and the much longer pedicel; from D. angustifoliiim RiDL. by the solitary 

 scapes, the lip not being narrow lanceolate, the shortly bidentate top wing 

 of the coliimn and the stelidia arising from above the base of it. 



The pseiidobulbs are described as orange red, the flowers as light green. 

 In the herbarium the pseudobulbs are distinctly yellow. The branches 

 collected hâve a length of aboiit 35 cm.
