middle, the sac or spur short broad and truncate; odd sepal 

 galeate, rising about 1 cm. high, the acute point deflexed nearly 

 to the base of the column ; petals obliquely lanceolate, very 

 acuminate, acutely toothed on the outer margin ; lip nearly 

 erect, rising from a ligulate base along the column, then expanding 

 upward into a somewhat fiddle shape, contracted and channelled 

 to the blunt glandular apex, appendage hanging from a little 

 above the middle in front, and reaching more than half-way 

 toward the base, acute, curved forward, flat appearing terete by 

 its revolute margins ; rostellary arms spreading horizontally, 

 apices dilated oblique recurved. 



Described from 2 living specimens from Grahamstown, which 

 are represented in the plate, but I afterwards saw some much 

 larger ones from Komgha. Colour of the flowers pale cream 

 yellow, with light green dots on the galea, and a hairy purple 

 patch on the petals. In the Kagaberg specimen the leaf was 

 very smooth and shining, and somewhat livid below. The 

 general structure of the lip is like that of D. secimda, but it is 

 more erect. Keichenbach's description does not agree well with 

 the plants I have examined, and was no doubt drawn up upon 

 dried specimens. But I have seen at Kew a drawing of his type, 

 with a copy of the attached label marked " Cap. B. Spei., Br. 

 Krehs (led. 1833," now in the Eoyal Herb. Berlin, with an 

 analysis of the flower, and this leaves no doubt of its identity. 

 Both Dr. Krebs' specimens have the pedicel and bract of a second 

 flower, which has either dropped or was aborted. Dr. Krebs 

 was resident for some time at or near Bedford, whence he sent 

 many plants to Europe, and he probably collected his specimens 

 of this species also on the Kagaberg.
