connected with the base, which has not already 

 been described. When the two halves of the ex- 

 pansion are of different lengths, this is observable 

 chiefly at the base, and the leaf is said to be un- 

 equal or oblique (basidncequale), 3O, (page 496). 



e. The Margin of a leaf may be either entire, 

 indented, bordered, or rolled. 



* Entire. 



An entire leaf (folium integerrimum) has the 

 line of the margin uninterrupted, or free from 

 every kind of incision or indentation. Sir J. E. 

 Smith properly remarks that this term refers 

 solely to "the margin of a leaf; whereas in- 

 " tegrum respects its whole shape, and has no- 

 " thing to do with the margin-^-." I may add, it 

 is used in contradistinction to compositum. 



** Indented. 



A leaf is termed sinuated (smuatum), 31, (page 

 498), when the margin is cut into roundish scollops, 

 as in the Oak, Quercus robur; but when the notches 

 or scollops are very irregular, as if formed by the 

 gnawing of some insects, the margin is then said to 

 be gnawed (erosus), 32. It is termed toothed (den- 

 tatus), 33, when it displays pointed marginal pro-

 them ; and the following terms are employed to 

 express the character of the margin as far as re-
