I take this opportunity of stating, that the genus Acan- 

 thophippium does not belong to VandecB, as I formerly sup- 

 posed, from the examination of an imperfect specimen, but 

 in reality should be stationed in Epidendrece, where it repre- 

 sents the Maxillaria of Vandese, and the Dendrobium of 



Malaxid 



iae ; an interesting fact with reference to systema 

 purposes. It should be placed near Bletia and Phaius

 and brighter underneath; the flowers are dull yellow,'
