It is commonly situated at the base of the 

 latter, in pairs, and is extremely different 

 in shape in different plants. 



The most natural and usual situation of 

 the Stipulas is in pairs, one stipula on each 

 side of the base of the footstalk, as in 

 Lathjrus latifolius, Engl Bot. t. 1108, 

 whose stipulas are half arrow-shaped ; also 

 in Willows, as Salix stipularis, t. 1214, 

 1 and S. anrita, t. 1487. In Rosa, Potcn- 

 tilla, and many genera allied to them, the 

 stipulas are united laterally to the foot- 

 stalk. See Potentilla alba, t. 1384. In 

 all these cases they are extrafoliace^ ex- 

 ternal with respect to the leaf or footstalk; 

 in others they are intrafoliacece, internal, 

 and are then generally simple, as those of 

 Polygonum, t. 1382, 756, &c. In a 

 laro-e natural order, called Rubiacece, these 

 internal stipulas in some cases embrace the 

 stem in an undivided tube above the inser- 

 tion of the footstalks, like those of Polif* 

 gonum just mentioned; in others, as the 

 Coffee, Coffea arabka, and the llamdlia 

 patens, Exot, Bot. t. 24, they are separate 

 Irnves between the footstalks, but meeting
