Apples and Crabs. — The difference between the well-lmown 

 crab apples and the so-called "apples" of our markets is well 

 known in a general way, but in some cases it is not very clear. 

 The term "crab" is applied in England to small, inferior seedlings 

 of the apple (Pyrus mains) , while here the same term is used to in- 

 dicate the crab apple (Pyrus boccata) , or its hybrids.

Pyrus mains, the true apple, is distinguished by leaves that 

 are woolly on the underside, woolly calyx and Hower stems. Fruit 

 various, but always holding the calyx, i. e., the parts of the flower, 

 on the end of the fruit. Leaves thicker and broader and the new 

 growth thicker and more woolly than in the crab.
