Hab. : Cape Colony, Eiversdale Division, in Garcia's Pass (Lange- 

 bergen), on rocky mountain sides, alt. about 1,800 ft., n. December 

 (1904), collected and sent by Mrs. C. Luyt ; No. 10571 in my herb, 

 (also in herb. Kew, &c). 



This much resembles D. Draconis, Swtz., but cannot, in my 

 opinion, be fitly placed in any existing section. From the § Cory- 

 phsea it differs by its rigid, wiry, grass-like leaves, the small, 

 subresupinate, uncinate petals, and the rather high rostellum. In 

 all these characters it approaches the § Herschelia. From the latter, 

 however, it is separated by the structure of the flowers generally, by 

 the very entire lip, by the two distinct glands of the pollinia and 

 the corresponding modification of the rostellum. There is nothing 

 in the structure of the flower to suggest hybridity.
