AND THEIR SYSTEMATICAL ARRANGEMENT. I09 



with two cells, between which and the correspond- 

 ing cavities of the style, the pollen masses are 

 found. 



In Epipactis it is fixed to the hinder part of 

 the upper end of the elongated style. 



In Cymbidium, Epidendrum, and in all the 

 genera which I shall hereafter notice, as having an 

 anthera opercularis mobilis, the style is generally 

 elongated. The anther in these is like a convex, 

 fleshy, or membranous lid, slightly fastened, as if 

 by an articulation, to the edge pointing towards 

 the back part. This is lifted up and often drops 

 off, as soon as the pollen issues from' the one, two, 

 or three cells, which open opposite the cavity at 

 the top of the style. 



Now as an anther consists of a loculament or 

 membrane in which the pollen is contained or 

 prepared, that part which I have just described 

 must be considered as such, and indeed as a single 

 anther, in all the Orchidese except in Cypripedium. 



The pollen, or that impregnating substance 

 which in the anthers of the Orchidece appears, as 

 it were, to constitute a distinct part, displays a
