ORCHIDACEiE 



ened where it joins the column. Gynostemium about 1.5 mm. 

 tall from the base to the tip of the apical wing. Stelidia very 

 broad, rounded at the tip, about .5 mm. wide, slightly longer 

 than broad, not equaling the tip of the apical wing, erect, rather 

 fleshy. Apical wing strongly concav^e, nearly orbicular, entire. 



The very broad lateral wings of the column and the simple 

 labellum indicate relationship with D. alatum Ames and D. jim- 

 briatum Ames. Unfortunately the material from which my de- 

 scription is drawn is incomplete, the tip of the raceme having 

 been broken off. (Plate 83.)
