margins revoliite, 6 mill, long, spur obtuse inflated about as long 

 as the limb ; clinandrium erect very obtuse, caudicle- bearing 

 arms of the rostellum short incurved, longer than the subulate 

 stigmatiferous processes. 



Described and drawn from several living specimens, for which 

 I am indebted to Mr. J. Glass, and which were much finer than 

 those from which my first description of the species was drawn 

 up. Colour of the flowers green. The leaves are occasionally 

 somewhat glaucous. The species is peculiar by its short flowers, 

 resembling those of H. laevigata^ Lindley (see preceding plate), to 

 which it is most nearly allied, but with a different lip and column. 

 The narrowing of the odd sepal and petals to a point is a marked 

 characteristic. The distribution is peculiar ; no doubt further 

 research will result in its being found betw^een Grahamstown and 

 the Trans Vaal.
