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 (jig. 526). 
In other cases the connective is very small, or altogether want- 
ing, as in species of Huphorbia (fig. 524), so that the lobes of 
the anther are then immediately in contact at their base. In 
the Lime the connective completely separates the two lobes of 
the anther (jig. 525). In the Sage (fig. 517) and other species 
of Salvia, the connective forms a long stalk-like body placed 
horizontally on the top of the filament, one end of which bears

Fig. 524. A male naked flower of a species of Zuphorbie, showing 
the two lobes of the anther, and the almost total absence of the 
connective.—Fig. 525. A stamen of the Lime (Tilia), showing 
the large connective separating the lobes of the anther. Fig. 
526. An inside view of a stamen of Magnolia glauca, showing the 
adnate anther and prolonged connective. Fig. 527. Two sta- 
mens of the Heartsease ( Viola t7icolo7’). The connective of one of 
them is prolonged downwards in the form of a spur. Fig. 528.

an anther lobe, / f, containing pollen, the other merely a peta- 
loid plate or abortive anther lobe, / s; it is then said to be dis- 
tractile. Sometimes the connective is prolonged beyond the 
lobes of the anther; either as a little rounded or tapering 
expansion, as in the Magnolia (fig. 526), or as a long feathery 
process, as in the Oleander (fig. 528), or in various other ways. 
At other times, again, it is prolonged downwards and backwards 
as a kind of spur, as in the Heartsease (jig. 527). Anthers with 
such appendages are termed appendiculate. 
Forms of the Anther Lobes and of the Anther.—The lobes of the 
anther assume a variety of forms. Thus in Mercurialis annua 
(fig. 530), they are somewhat rounded ; very frequently they are 
more or less oval, as in the Almond and Lime (jig. 525) ; in the 
Acalypha they are linear (fig. 529) ; in the Gourd tribe (fig. 531) 
linear and sinuous; in the Solanwm (fig. 539) four-sided ; and 
at other times pointed, or prolonged in various ways. These
