in size and shape. Some are large and broad, some 

 long and narrow ; these again being in some cases 

 sagittate, in others half-sagittate. 



Lathi/rus mantinvus belongs to the first cate- 

 gory. The stipules (figs. 296 and 297) are large, foli- 

 aceous, and develop early. The stipules of the common 

 Garden Pea have already been described and figured 

 (see ante, p. 23).

Stipules of Lathyrus maritimus. One-and-a-half nat. size. 

 In Fig. 297 one of the stipules is turned back, revealing the rest of the leaf and bud. 



In L. grandiflorus (fig. 298) they are small, half- 

 sagittate, narrow, and pointed. The upper and lower 

 limbs, moreover, do not lie in the same plane, but are 

 somewhat twisted relatively to one another. 



In other species, as for instance in L. pratensi<t (fig. 

 299), they are sagittate.
