ORDER LVII, ROSACEA. 



The name of this Order will be sufficient to indicate one of its 

 most prominent members, the rose, but in addition to this it most 

 probably includes more fruit-bearing trees than any other Order, an 

 enumeration of which may not be out of place here. They are as 

 follows : — Almond, Apple, Apricot, Blackberry, Cherry, Cocoa Plum, 

 Loquat, Medlar, Nectarine, Peach, Pear, Plum, Quince, Raspberry, 

 Strawberry, and others which are less well known. Among our 

 indigenous species the only ones bearing eatable fruits are the four 

 species of Rubus, our native blackberries. None of the other genera 

 contain species of any economic value, though Agrimonia Eupatoria 

 has been used medicinally. 



Nuanber of species about 1000.
