flowers erect or ascending^ ; bracts herbaceous, ovate or lanceolate, 

 shorter tlian, or more rarely as long- as, the ovary ; lateral sepals 

 spreading ovate-oblong- emarginate undulate keeled, condupHcate 

 at the apex, 1-2-1 '4 cm, long ; odd sepal anterior horizontal 

 cucullate obtuse, compressed towards the apex, about as long as 

 the lateral sepals ; petals decumbent oblong very obtuse, incurved 

 at the apex denticulate and pubescent on the outside, auriculate 

 on the posterior margin at the base, 0-8-0-9 cm. long ; lip projecting 

 forward subulate acute, widened and toothed above the base, as 

 long as the petals ; rostellum erect 3fid, the intermediate lobe 

 reflexed, shorter than the lateral lobes ; anther strongly resupinate, 

 the glands approximate ; ovary straight, with the pedicel 1-1 -o cm. 

 long. 



Described from several dried and living specimens. The 

 drawing was made from a living plant collected on the Muizenberg. 

 {Bolus, 4638.) 



The colouring is very peculiar. The side sepals are divided in 

 this respect longitudinally into two parts, the anterior half being 

 white, the posterior half black-purple on the outer or lower side, 

 deep crimson on the upper ; the hood greenish white and veined ; 

 the petals and lip pale green variously mottled with purple. 



Very closely allied to D. bivnlvata and may be distinguished 

 (1) by the shape of the hood which is more beaked, and (2) by the 

 colouring.
