DICOTYLEDONS 



The Rose family (Rosacece) is but little represented on the 

 plains of India. Many fruits, such as the Apple, the Pear, 

 the Almond, the Peach, the Cherry, the Plum, Strawberries and 

 Ptaspberries belong to this family, but come to perfection only in 

 cooler climates. Ruhus ellipticus (tig. 48), R. moliiccanus, and 

 R. lasiocarpiis are very common on the hills.
