274 CHERRY : PEAR 



sub-coriaceous, not pendent, dark shining green, slightly 

 pubescent when young. Petiole eglandular, or occasionally 

 with 1 2 glands at the top or on the base of the lamina. 

 (See p. 270.) Autumn leaves red and yellow. Leaves 

 conduplicate. Flowers with the leaves. Stipules subulate, 

 often toothed and glandular, caducous. 



Venation like that of P. Avium, the looping perhaps 

 more pronounced. 



8 8 Leaves convolute. 



Forms of Prunus spinosa, devoid of thorns, and of its 

 varieties P. insititia and P. domestica, may be looked for 

 here. See p. 267. Also P. Padus, when the petiolar 

 glands are, as sometimes occurs, obsolete. See p. 271. 



[Several of these species of Prunus have resemblances, 

 more or less, to certain Willows; but the numerous 

 scales to the buds and the narrower leaf-insertions at once

Leaf-insertion long and narrow, cres- 

 centic, and extending about half-tvay 

 round the shoot. 



Jf Leaves involute in bud; dwarf shoots 

 sharp or even thorn-like; buds with 

 several scales. 



Pyrus communis, L. Pear (Fig. 104). Medium tree, 

 with leaves scattered on the long shoots, fascicled on the 

 often thorn-like dwarf shoots on older branches. Leaves 

 ovate or obovate to oblong-ovate, ovate-lanceolate, oblong, 

 elliptic or sub-rotund, about 35 cm. long (3 10 x 3 6 

 cm.) ; shortly acuminate to obtuse, finely obtusely serrate 

 or almost entire, especially at the base, which may be 

 rounded, or rarely slightly cordate or attenuate ; somewhat 

 tomentose when young, becoming glabrous, or occasionally
