AND THEIR SYSTEMATICAL ARRANGEMENT. II5 



the lip, as also Epidendrum, Arethusa, &c. but in 

 these latter before the anther, perhaps also beneath 

 it. In Cypripedium, the stigma is more distinct 

 than in any other; it is crooked, hollow, and pro- 

 boscis-like, and situated at the end of the style. 



The moisture issuing front the stigma renders it 

 shining and visible. The small particles, globules 

 or vesicles of the pollen-masses, accumulate and 

 dissolve upon it. These particles I have seen upon 

 the stigmas of several species of Disa, and in great 

 abundance deep down the singular channel of the 

 calyx of Orchis burmannia L. (O. pecttnata Thunb. 

 Capens.) the stigma of which is situated near the 

 upper end of the germ. They dissolve upon the viscid 

 stigma ; by which perhaps is caused the peculiar 

 smell that the sexual parts of even the well scented 

 Orchidea? diffuse when touched ; and which is 

 even to be perceived, many years after, in their 

 flowers, if soaked in warm water. 



The mode of fructification in these plants is not 

 less remarkable than the organs employed in it.
