CHAP. VII. 

 OF DETERMINATE LEAVES. 



BY the DETERMINATION of leaves is to be un- 

 derstood their character, expressed from some cir- 

 cumstance foreign to their own particular structure 

 or configuration ; as from their place, situation, in- 

 sertion, or direction. 



By the PLACE of a leaf is meant the part where 

 ,it is fastened to the plant. In respect to which, 

 leaves are called, 



Seminal, seed leaves ; which before were the co- 

 tyledons, and are the first which appear. 



Radical, root leaves ; such as proceed from the 

 root. 



Cauline, stern leaves ; such as grow on the stem. 



Rameous, branch leaves; such as grow on branches. 



Axillary*, such as are placed at the coming out of 

 the branches. 



Floral, flower leaves ; such as are placed at the 

 coming out of the flower. 



By SITUATION is meant the disposition of the 

 leaves on the stem of the plant. In respect to which 

 leaves are called, 



Stellate, starry ; or verticillate, whorled ; when the 

 stalk is surrounded in whorles by more than two 

 leaves : And these again receive the denomination of 

 Tern, Quatern, Quine, Sene, c. according to the 

 number of leaves of which the star or whorl is com- 

 posed ; as in Nerium, Brabejum and Hippuris. 



* From Axilla, an arm-pit.
