n6 SWARZ ON THE GENERA OF ORCHIDEiB, 



something concerning this operation, in those spe- 

 cies which have fallen under their inspection. In 

 orchis, and those l genera, the pollen-masses of 

 which are furnished with a thread-like pedicle, 

 these are ejected, on the unfolding of the flow T er, 

 out of .their cell, and, either by elasticity, or (ac- 

 cording to Sprengel) by the assistance of insects, 

 find their way to the stigma. In Epipactis, Neottia, 

 Cranichis, and others that have no pedicles to the 

 pollen, the pointed ends of the masses are stuck to 

 the opposite gland, and thus brought nearer to the 

 stigma. But in those genera that have a moveable 

 anther situated upon the top of the style, as Are- 

 thusa, Epidendrum, Cymbidium, &c. it is lifted up 

 backwards like a lid, by' which means the pointed 

 parts of the pollen-masses, fixed to the foremost 

 and projecting upper part of the style, remain in 

 the cavities beneath the anther, and thus find the 

 way, without difficulty, to the neighbouring stigma. 

 In Cyprepedium, the sexual parts of which are still 

 more distinct, the dilated stigma stoops, towards 

 the anthers, which are situated underneath at the 

 sides of the style. Those species, the floral parts
