adnate or dorsifixed -when its back is attached tlironghout its 

 whole length to the filament, or to its- continuation the con- 

 nective, as in the Magnolia {fig. 350), and Water-lily (fig. 

 346) ; 2nd, it is innate or basifixed when the filament is only 

 attached to its base, and firmly adherent,, as in the species 

 of Carex (%. 329) ; 3rd, it is versatile, when, the filament is 

 only attached by a point to about the middle of the back of 

 the connective, so that the anther swings upon it,_ as in Grasses 

 generally [fig. 331), and in the. Lily,-:Eyening.Prijnrosfi, 'and

Connective. — The relations of the anther to the filament, as 

 well as of its lobes to each other, are much influenced by the ap- 

 pearance and size of the connective. Thus in all adnate anthers 

 the connective is large, and the lobes generally more or less 

 parallel to each other throughout their whole length {fig. 350). 

 In other cases the connective is very small, or altogether want- 

 ing, as in species of Buphorhia {fig. 348), so that the lobes of 

 the anther are then immediately in contact at their base. In 

 the Lime the connective completely separates the two lobea of 

 the anther {fig. 349). In the Sage (fig. 343) and other species 

 -of Salvia, the connective forms a long stalk-like body placed 

 horizontally on the top of ihe filament ; one end of it bierars
