Plate 44. Fig-. 1, flower, front view ; 2, ditto, viewed from 

 above ; 3, one of the side sepals, under side ; 4, odd sepal, front 

 view ; 5, one of the petals ; 6, lip ; 7, column with petal and lip,

The drawing of the analytical figures was made from a flower 

 sent by Dr. Watson in Nov. 1894 from Ladismith, Cape Colony ; 

 of the whole plant from one which Mr. N. S. Pillans brought from 

 the same place in Nov. 1906. 



This form differs from the more typical one of the species, 

 figured under /. 32, vol. i. of this work (where the description, etc., 

 will be found), in having somewhat larger and more deeply 

 coloured lilac flowers.
