 founded with Ovate. If an oblong or an 

 oval leaf possess a regularly rounded 

 outline into and through the apical and 

 basal portions it is called Elliptical. We 

 have, therefore, two forms of the ellipti- 

 cal leaf, denominated respectively Ob- 

 long-Elliptical (Fig. 40G) and Oval-Ellip- 

 tical (Pig. 407). A circular leaf (Fig. 

 409) is called Rotund or Obicular. Final- 

 ly we have the leaf which is broader 

 than circular— that is, its lateral diameter 

 is greater than its vertical, and this is 

 called Transversely Elliptical. 



have it specified in some way as to about 

 the portion at which the greatest breadth 

 occurs. Beginning with the broadest 

 ones we have that which is broader than 

 long and with a heart-shaped base, called 

 Reniform (Fig. 410). One which pos- 

 sesses a length greater, but not more 

 than two or three times its breadth, is 

 called Ovate (Fig. 411). One of similar 

 form, but its comparative length greater, 

 is called Lanceolate (Fig. 412). One 

 which is ovate, but with the greatest 

 breadth at the very base, the margins not 

 or but little curved, so that it is approxi-
