been printed in Hooker's Journal of Botany, volume 3, page 

 81, to which the reader is referred. Among other sections in 

 that place proposed, is one characterized by the presence of 

 pseudobulbs and the more or less complete separation of the 

 lip from the column, to which, as it includes Sir William 

 Hooker's Encyclia, the name of Encyclium was assigned. As 

 the species of that division are common in our gardens, and 

 may possibly be regarded by some as a groupe of generic 

 value, and as they are a good deal confused, and demand a 

 more precise sub-division than that temporarily assigned them 

 in the work above quoted, the present opportunity is taken of 

 laying a revision of the whole of the Encyclia before the reader. 

 La Llave and Lexarza divided these plants into two sec- 

 tions, distinguished by the racemose and panicled inflores- 

 cence, a division I formerly adopted ; but I find that although 

 the distinction would probably be valid, if we could always 

 have the species before us in a perfect state, yet that it leads 

 to confusion in consequence of the panicled species often being 

 merely racemose when weak, and ill grown. It is therefore 

 now proposed to found the divisions upon the form of the lip, 

 as a more certain and uniform mark of distinction. This 

 again affords three principal, and three subordinate charac- 

 ters. It is— 1. perfectly undivided, or it is, 2. slightly 

 3-lobed, or it is, 3. split into three deep divisions ; these are 

 the differences regarded of the first degree of importance. 

 The third of these sections may be itself subdivided by the 

 form of the middle lobe of the lip, which is— 1. acute, 2. 

 rounded, or 3. two-lobed. By this method the following will 

 be the arrangement of the Encyclium division of Epidendrum, 

 as far as I am at present acquainted with the species.
