202 BUDS AND STIPULES 



coloration, leur forme et leur position, sont entierement 

 differentes des folioles, et s'harmonisent tout a fait 

 avec les stipules que Ton trouve dans la plupart des 

 Legumineuses ' (28). 



The same may also be said of the allied genera 

 Dorycnium, Bonjeania, &c. 



Cambessedes, however, maintains that the true 

 stipules of Lotus and the other genera mentioned are 

 two minute glandular elevations at the base of the leaf. 



The Leguminosce, to which these genera belong, are 

 as a rule stipulate ; so that if this view is correct we 

 have an interesting case in which the stipules have 

 dwindled away, and their function is performed by the 

 lower leaflets, which have to some extent wandered 

 away from their usual position in order effectively to 

 take on this new duty. 



Again, the tendrils of Cucumbers (Cucurlitacece) 

 and Smilax have been regarded by some botanists as 

 stipules, while this has been denied by others ; and the 

 same difference of opinion has existed with reference 

 to the ligule of grasses. 



I shall presently return to some of these doubtful 

 cases. 



HeUanthemwm guttatum is a very interesting species. 

 As Dr. Stenzel (29) points out, the lower part of the shoots 

 bears lancet-shaped leaves without stipules. Nearer the 

 flower-buds the leaves tend to become smaller, and have 

 stipules. These are linear, and attached quite at the
