THE ORCHID REVIEW. 267 
together in subordinate groups is easily understood. It is also clear that 
the difficulty above alluded to about their nomenclature does not arise so 
much about the amount of difference between the various forms as about 
the value to be attached to these differences in the scheme of classification. 
A good deal of additional information has come to hand since any attempt 
was made to ascertain the relation of the different forms to each other, and 
a revision of the genus in the light of the above remarks would inevitably 
lead to considerable improvement in their arrangement and nomenclature. 
The following is a rough outline of what we believe to be a fairly natural 
arrangement of the various forms, so far as our knowledge and a linear 
sequence permits, commencing, as we apprehend, with the more simple 
forms and progressing towards the more highly developed ones :—
