This name is applied to the cultivated pear in its many pomological forms. The trees are usually larger than those of the wild pears and are without thorns. They differ also in having larger leaves, and larger and better-flavored fruits.
PYRUS COMMUNIS CORDATA Hooker
1. Hooker, J. D. Stud. Flora 131. 1878.
2. P. cordata Desvaux Obs. Pl. Anjou 152. 1818.
This botanical variety is a spiny shrub or shrub-like tree. The leaves are smaller than those of the species, 1 in. in width, suborbicular to ovate, subcordate at the base. Flowers smaller. Fruit globose or slightly turbinate, very small, ½ in. in diameter; calyx persistent. The species is a native of western France and is found in Devon and Cornwall, England. This species is said to propagate itself freely from root-suckers which suggests that it might be tried as a dwarfing stock for the common pears.
