of the difference in the colour and size of its flowers, it has 

 exceedingly acuminate sepals and petals, and quite another 

 kind of appendage to the stalk of the labellum. Before I had 

 seen the plant now figured I was disposed to believe that 

 species to be the O. maculatum of La Llave, as is stated in 

 the Sertum Orchidaceum, so very difficult is it to judge cor- 

 rectly of the insufficient descriptions of the Mexican Botanist. 

 I now find that they are truly distinct.
