In Colonial times the wild, or Virginian, strawberry, with itsseveral varieties, was cultivated in American gardens, but of lateyears has been supplanted almost entirely by the numerous deriva-tives of the Chilian species, although wild strawberries are stillgathered in considerable quantities in the meadows.

Macroscopic Structure.—The cultivated strawberries [F. Childensts)are usually of large size (often 3 to 5 centimeters in diameter), andbear the achenes in deep depressions. Berries of the wood species [F. vesca) are of small size (seldomover I centimeter in diameter), and bear the achenes in shallowdepressions. Berries of the Virginian species are of about the same size as thewood strawberries ; but like the cultivated berries, the achenes aredeeply sunken in the receptacle. The receptacle, the edible part of the strawberry, consists of asomewhat fleshy pith, a still more fleshy cortex, and between thetwo a narrow zone of fibro-vascular bundles, from which branchesshoot off through the cortex to the achenes. {Fig. i, I.)
