 apicem lobi medii 2 mm. longum ; lobi 

 laterales majores, falcati, acuti ; lobus 

 medius retusus, mucronatus. Calli 2, 

 ex comparatione magni. Columna 

 ut in D. pumilo. 



According to field notes the flower 

 in a fresh state was white with red 

 centre. From this statement it is 

 highly probable that the sepals and 

 petals were white and the lip of a 

 reddish or purplish color. The stouter 

 rhachis, more strict inflorescence, and 

 very different sepals are characters 

 which serve readily to distinguish 

 D. simulacrum from D. pumilum. 

 From D. affine it is clearly distin- 

 guished by the middle lobe of the lip being smaller than the lat- 

 eral lobes. Both D. pumilum and D. affine possess a flexuose 

 almost filiform peduncle, which serves to separate them at a 

 glance from D. simulacrum.
