A very distinct species, in floral structure nearest to D. pulclira, 

 Sond., of which, though dissimilar in appearance, it might be 

 regarded as a miniature Western representative. The petals in 

 this, however, are very different, and the rostellum is propor- 

 tionately much higher. In its inflorescence and the general shape 

 of the flowers it is strikingly like D. gladioli flora, Burch. (which 

 Schlechter has placed in the § Oregura), but is at once distinguish- 

 able from that by its herbaceous expanded leaves and the high sub- 

 erect rostellum. It has also some relation with the very different- 

 looking D. caffra, mihi, and I should place it between that and 

 D. pulclira.
