variety, in the genera and species of Orcliideous plants. In 

 this however I am satisfied that I was wrong, as will I think 

 be evident from the following comparison of the two species 

 as they were seen last year in the stove of the Messrs. 

 Loddiofes. 



't>^ 



O, altissimum, Pseudobulbs nearly round, very much compressed, and two- 

 edged. Leaves acute. Raceme decumbent nearly simple. Colours of the 

 flower very bright. Wings of the column rounded and a little crenelled. 



O. Baueri. Pseudobulbs oblong, a little compressed, only slightly two-edged. 

 Leaves broader, and rather acuminate. Raceme erect, very compound. 

 Colour of the flowers rather dingy. Wings of the column very remarkably 

 truncated. 



It is impossible, now that these differences are made out, 

 to combine the two plants as I once proposed. I therefore 

 avail myself gladly of an opportunity afforded me by Messrs. 

 Loddiges of figuring the true O. altissimum; and for the 

 satisfaction of those who may not have access to the work in 

 which it was first described, I have added the very words of 

 Jacquin in speaking of that species. 



The O. altissimum figured at fol. 1651 is the true 

 O, Baueii.
