H. lactiflora labelli lobis lateralibus versus mediam partem enatis linearibus, 

 intermedio ovali, oblongo, obtuso." Rich, h Gal. loc.cit. 



No type of H. lactiflora is designated, and it is clear that 

 Richard referred specimens of ^. diffusa and H. clypeata to it, 

 as may be seen by specimens at Paris. (Richard's drawing is of 

 H. clypeata'^.) Certainly Galeotti no. 5218 is not the type, as it 

 has a question mark after it; yet its aspect is more like what 

 must be held as H. lactiflora. There is a drawing in the Lindley 

 Herbarium that shows a flower very much like Heyde & Lux 

 no. 3858 (which I refer to var. buccalis Reichb. f.). This species 

 may be distinguished readily from H. clypeata, which it closely 

 resembles, by the lateral arms arising from near the middle of 

 the lip and the oblong mid-lobe. Lindley 's drawing shows these 

 characters perfectly. (A. A. E.)

 The status of H. lactiflora Rich. & Gal. in this monograph is 

 based on Eaton's notes made at Paris in November, 1905. In 

 order to make these notes as clear as possible the accompany- 

 ing plate has been prepared to represent the drawing by Richard,
