Naturalised throughout India. 



A small tree, pubescent on the young branches. Leaves on very short petioles, 

 ovate or oblong, and usually acuminate, 3-4 in. long, glabrous or nearly so above, 

 softly pubescent beneath and with the principal nerves prominent. Peduncles 

 axillary, in., 1-3-flowered ; buds ovoid in the adnate part, the free part also ovoid 

 but larger and more or less pointed. Petals broad, ^ in. in diameter. Fruit globose or 

 pear-shaped. "Indigenous in Mexico and possibly in other parts of Tropical America, 

 cultivated and naturalised in most tropical countries. In India the Guava is culti- 

 vated almost everywhere except in the north-western corner of the Punjab. It often 

 run wild, but there is no ground for supposing that the Guava is indigenous in India. 

 "Wood compact, close-grained, takes a beautiful polish." (Brandis I. c.)
