16 STAMEN. 



The Anthers are usually distinct from each 

 other, but they are sometimes united, as in Leon- 

 todon, fig. 2. 



To each filament there is generally one anther, 

 but in Mercury, (Mercurialis) there are two to 

 each filament, and in Fumitory, (Fumaria) there 

 are three. 



The form of an anther is either. 

 Globular, as in Mercury, fig. 3. 

 Arrow-shaped, as in Crocus, fig. 4. 

 Forked, as in Vernal-grass, (Anthoxanthum) 

 fig. 5. 



The situation of the Anther is not always on 

 the summit of the filament. In Herb-paris, it is 

 on the side ; in Arum it grows from the receptacle 

 without a filament ; and in Orchis it is seated 

 upon the pistil. 



Although the Pollen appears to the naked 

 eye a fine powder, yet the granules are, in diflferent 

 plants, variously formed. By microscopic inves- 

 tigation they have been discovered to be perforated 

 in Crane's-bill, (Geranium ;) wheel-shaped, in 

 Narcissus ; angular, in Violet ; and resembling a 

 rolled up leaf, in Borage, (Borago)
