Shape. 



Juvenile leaves shapes cluster about (a) the line and (6) the circle. 



The following are the terms I propose to employ in dealing with these shapes, 

 although very many more will be found in descriptions, and in some species the amount 

 of variation is surprising. In a few cases the same species -will be found in more than 

 one list. 



(a) 1. linear. 



2. Linear-lanceolate to narrow-lanceolate. 



3. Lanceolate. 



4. Lanceolate, with cordate base. 



(b) 5. Broadly lanceolate to nearly orbicular. 



6. Orbicular. 



7. Orbicular (or nearly so), with cordate base. 



What follow are not complete lists, but they may be useful as a guide. 

 With reference to a (4) and b (7), the leaves with cordate bases will be found referred to 

 with respect to the classification by petiole, or absence of it, p. 308. It will be found 

 that the preponderating shape in juvenile leaves tends to the broad, or orbicular.
