are then immediately in contact at tlicir bases. In the Lime 

 the connective completely separates the two lobes of the anther 

 ijig. 512). In the Sage {fig. 505) and other species of Salvia, 

 it forms a long stalk-like body placed horizontally on the top of 

 the filament, one end of which bears an anther lobe containing 

 pollen, the other mei'ely a petaloid plate or abortive anther lobe ; 

 it is then said to be distractile. Sometimes the connective is 

 ])rolonged beyond the lobes of the anther ; either as a little 

 rounded or tapering cellular expansion, as in Magnolia {fig. 

 513), Asarum, &c., or as a long feathery process, as in the 

 Oleander {Nerium Oleander) (fig. 515), and in various other 

 ways. At other times again, it is prolonged downwards and 

 backwards as a kind of spur, as in the Heartsease (fig. 514), 

 &c. Anthers with such appendages are termed appendiculate. 



Form of the Anther Lobes, and Anther. — The lobes of the 

 anther assume a variety of forms. Thus in Mercurialis annua 

 (fig. 517), they are somewhat rounded, very frequently, they 

 are more or less oval, as in the Almond (fig. 5 \ 8), in the 

 Acalypha, they are I'mear (fig. 516), in the Gourd tribe

 These forms combined with those of the connective determine 

 that of the anther ; which may be oval, oblong, &c. ; or bifurcate 

 or forlivd, as in the Vavcinium uliginosum {fig. 521), or quadri- 

 fiircate (fig. 522), as in GuuUlicria procuiiibeus, or sagittate 

 (fig 51.';;, as in the Oleander, or cordate, as in the common 

 VVallllower (figs. 422 and 423) ; in the Grasses tlic anthers are 

 l)ifiircate at cacli extremity (fig. 490), so as to resemble somewhat 

 the letter x in form. 



The lobes of the anther also, like the connective, frequently
