In respect to composition, digitate leaves will fre- 

 quently gain an addition of one or more folioles*. 



Crisp, curled leaves, are a very frequent variety. 

 In Tanacetum, Mentha, Ocyrnum, and Matricaria, 

 which are scented plants, there is a singularity ob- 

 servable, that when the leaves are curled, the scent 

 is heightened by the crispaturef. 



Bullate, bladdery leaves, are generally produced 

 from such as are rugose, wrinkled ; and this is 

 owing to the increase of the substance of the leaf 

 within its vessels, which occasion it to swell and rise : 

 In the Saponaria concava Anglicana, a bullate leaf 

 is produced in a singular manner from the defect of 

 wrinkles ; for here the margin of the leaf contract- 

 ing itself, the leaves become hollow like a spoon J. 



Plants are sometimes found to vary from broad 

 leaved to narrow leaved ; but this variation is less 

 frequent .
