LEAVES. 



Ctliate, when the teeth and angles are very acute. (Fig. 69.) 

 Erose, when the edges of the leaf look as though they were 



bitten or gnawed. (Fig. 70.) 



Palmate, when divided so as to resemble a hand. (Fig. 7l.) 

 Sinuate-lobed, when the depressions are broad at the bottom.

Pinnatifid, when the lobes go near to the middle. (Fig. 73.) 

 Runcinate, when the divisions of a pinnatifid leaf are more 



or less triangular, and pointing downwards. (Fig. 74.)

Runcinate leaf. 



Pan-shaped or Flabellate, as in the Palmetto. (Fig. 76.)

92. The extremities of leaves are acute when they terminate
