' This genus is one of those large assemblages of species, 



which hai been so much increased by modern discoveries as 



no longer to resemble what it was only ten years ago. Ut tne 



numerous kinds defined since the publication of the Genera 

 and Species of Orchidaceous Plants in 1830, the greater part 

 have been made known in a desultory manner, so that a 

 Botanist finds it difficult to compare them with each other. 

 They have moreover been insufficiently classified, « ««■ 

 quence of which the difficulty of their determination has been 

 much increased. It therefore seems to me that a comp cte 

 recapitulation of all that are known up to the present time 



cannot be otherwise than useful ; the more espec .ally j as Jtar 



smallness, and the minuteness of the characters by _ wh ch 

 they are known, are sufficiently embarrassing even when the 

 -position of the species is as clear and well arranged as art 

 J. „.„.„ it. Let me be permitted however v before jo.ng 

 into an enumeration of the species of this genus, to 

 few general observations on the genera allied *?";,,.., 



Among Malaxeous Orchidacea,, ^"^"^Ir inthl 

 forms the type of a very ^tural group; which, however. n the 



Genera and Species of Orchidaceous Plants is not sufficiently 



make
