Dr, Lindley lays stress upon, available ; viz, that on the labellum of (?. aurca there are five principal ridges, and three 
minor ones on each side, all downy and diverging, 'while in C, hractescem there are five equal ridges all smooth and 
parallel. In our drawing of C. hractmcem^ now before us, the five ridges are all downy in their lower half, while Jn 
G* aureay both a and ^3, the three lesser lateral ridges appear rather a kind of venation, such as is seen in the middle lobe 
also* In (7. hractescens, the bracteas are larger and very concave, and the flowers are larger, and the lateral lobes of the 
labellum are larger than in C. aurca. The flowers are very fragrant.* " 
Upon again referring to the materials in our possession for illustrating the differences in the three species 
of CkysiSf we find little to alter in what was 
formerly said about them. The principal ridges at 
the base of the lip of Ch. hractescens are, no doubt, 
downy half way up, as Sir W, Hooker states, and 
they vary in number from 5 to 7 ; but they are much 
blunter than in Ch, aurea^ and the lip is wholly desti- 
tute, in our speclmeus, of the lateral hairy veins 
peculiar to Ch. aurea. The most material difference 
between these species is, however, the great inflated 
bracts of Ch, bractescensy to which there is no approach 
in CL aurea. As to Ch, Icevis it has the bracts of 
the latter, from which it is distinguished by a shorter 
middle lobe of the lip and smooth short ridges, the 
two lateral of which are rudimentary.
