bilobed, the lobes equal rounded and very obtuse ; lip linear 

 obtuse shorter than the sepals or petals ; rostellum erect, with a 

 fold on either side turned back externally upon itself. 



Described from numerous living specimens. Colour of the 

 sepals dingy pale yellow, usually with reddish tints at the tips of 

 the side sepals and over the whole back of the galea, but some- 

 times entirely free from red ; petals and lip bright yellow. I am 

 indebted for the detection of this species to my relative, Mr. 

 Alfred Bolus. It is somewhat intermediate in character between 

 D. rufescens, Sicartz, and D. pijgmcsa, mihi, but quite distinct 

 from either. From the first it differs by its wider galea, 

 narrower lip, deeply lobed petals, and different column and 

 pollinarium ; from the latter by its long filiform spur, differently 

 shaped petals, and larger size. At its flowering period the 

 leaves are generally withered. The flowers appear to vary in 

 size more than is usual. It was tolerably abundant where found, 

 though, so far as hitherto known, confined to an area of two or 

 three acres.
