WHITE POPLAR: FIG, ETC. 223 



* Lobes triangular-ovate, deeply incised, 

 irregularly sinuate-dentate, or bluntly 

 toothed. 



Populus alba. The leaves on suckers and strong 

 shoots are often large and 3 5 palmatifid. Thick and 

 tough, smooth above, white-tomentose beneath ; the lobes 

 unequally sinuate, cut and toothed, and up to 15 cm. or 

 more in diameter (see p. 208). 



** Lobes acutely triangular, and sharply 

 serrate ; venation pseudo-palmate. 



Pyrus torminalis. The leaves are really pinnately 

 lobed and veined, but sometimes the lowest lobes and 

 secondaries are so strong and divergent as to be pseudo- 

 palmate, and the student may seek for them here (see 

 p. 205). 



(/3) Leaves not tomentose or hoary below. 

 * Leaves containing white latex. 



t Leaves thick, with large pulvini and leaf- 

 scars. 



Ficus Carica, L. Fig (Fig. 76). Shrubby tree, with 

 very variable leaves, and milky juice. The leaves (8 16 

 x 6 18 cm.) may be nearly entire, with pinnate venation; 

 but are more commonly palmately 3 7 -lobed, or even 

 5-partite, and veined, cordate at the base, each lobe more or 

 less rectangular or rounded, long, with dilated ends, obtuse 

 or acute, sinuate or again cut, and separated by shallow or 

 very deep wide sinuses. Lamina thick, dark green and 

 scabrous above, and pubescent or nearly tomentose and 

 paler beneath. Base cordate. Petiole stout, 2 5 cm. long. 

 Young leaf convolute. 



The lowest leaves nearly entire, rounded ovate, with 

 more or less tapering base. Autumn leaves yellow.
