falcate, thickened in front, papillose ; lip viewed from the front 

 oblong, very obtuse, viewed from the side clavate thickened and 

 fleshy, 3-4*5 mill, long ; rostellum erect, obovate, with an ear- 

 like fold on either side towards the apex. 



Described from the specimens quoted above, the figure of the 

 whole plant drawn from Mr. Schlechter's. In the latter, the 

 flowers were dingy yellow tinged with red-purple ; in Mr. Guthrie's, 

 yellow only. The chief characteristic is in the thickened lip and 

 petals, and the auricled rostellum. It comes near to D. multi- 

 flora, mihi, in its flowers, but the spike is always slenderer, and 

 the inflorescence usually less dense. It also somewhat resembles 

 D. micrantha, but the flowers are larger, and the spur and 

 column very different.
