the mouth suborbicular, 1*4-1 '6 cm. in diameter, subacute, spur 

 ascending obtuse about 4 mill, long ; petals included within the 

 galea, supine, somewhat hatchet-shaped, rounded and toothed 

 at the apex, widened and adnate to the column at base ; lip 

 spreading ovate cuspidate more or less crenulate, margins in- 

 flexed ; anther resupinate, the single gland of the pollinia trans- 

 versely oblong ; rostellum 3-lobed ; ovary slender decurved. 



Described and drawn from a living plant from the station first 

 above-named. Colour of the sepals blue, the lip and parts of the 

 petals violet, upper limb of the petals and spur yellowish green, 

 anther cells pink. Variable in the toothing of the lip, which is 

 sometimes nearly entire. Closely allied to D. graminifolia, Ker 

 (see Plate 37 in the first part of this work) ; but, besides the 

 considerable difference in the lip, the flowering season is widely 

 difterent, and I have no doubt as to its specific distinction. The 

 species seems to be confined to the southern part of the Cape 

 Peninsula; south of Simon's Town it may often be found in 

 quantity.
