it to the synonymy of H. viacroceratitis. This treatment is in- H. Pringlei 

 comprehensible as the same specimen is cited by Kranzhn under 

 both H. Pringlei and H. macroceratitis. If number 3823 of 

 Pringle's Mexican collections is a mixture, this fact is not men- 

 tioned in Kranzlin's work. As H. Pi^inglei is reduced to syno- 

 nymy on page 192, it is presumable that Kriinzlin reversed his 

 conclusions, indicated on page 188, in subsequent examinations 

 of material (cf. p. 887 Orch. Gen. et Sp.). The elongated, ensi- 

 form leaves, broad divisions of the petals and labellum, shorter 

 spur, and very characteristic inflorescence are only a few of 

 the salient details which serve to distinguish H. Pringlei from 

 H. macroceratitis.
