sagittate (a. sagittata], when the upper portions only of the cells are united by the 

 connective, and the lower portions slightly diverge (Wallflower, fig. 11 ; Oleander, 

 fig. 340). The anther is usually ovoid, but 

 may be oblong, elliptic, globose, square, &c. ; 

 it is acute in the Borage (fig. 322), and 

 sinuous in the Melon (fig. 317). 



The connective is sometimes developed

transversely, when the two cells are placed wide apart ; in the Lime (fig. 336) the 

 filament appears to bear two unilocular anthers ; in the Periwinkle (fig. 337), the 

 cells are separate and tipped by a very thick connective ; in the Sage (fig. 338) the 

 connective is greatly produced, forming a bent arm, longer than the filament, and 

 bearing a cell at either extremity ; of these cells one alone contains pollen, the 

 other usually enlarges into a petaloid scale ; in the Rosemary (fig. 339) the second 

 cell completely disappears. 



The anther is often appendiculate. In the Heath (fig. 334), the appendages

appear at the base of the cells as two small petaloid scales. In the Oleander (fig. 

 340) the connective is lengthened into a long feathery bristle. In the Periwinkle 

 (fig. 337), the prolongation of the connective is large and hairy at the tip. In the 

 Heartsease (fig. 341), the connective of two of the stamens lengthens above into a 

 yellow, flat, triangular scale, and below into a glandular spur, which is lodged
