862 USEFUL PLANTS OF GUAM. 
Indigenous to Mexico and other parts of tropical America, now spread throughout 
the warmer regions of the globe. In Guam, as in the Hawaiian Islands, it forms 
extensive thickets or patches of scrubby growth on abandoned fields and open places. 
It will not grow in the shade of the woods. The fruit is of good quality, but owing 
to scarcity of sugar on the island the natives do not utilize it much for making dulees. 
The wood is sometimes used for making tool handles and for fuel.

A shrub or small tree with oblong, obovate, or lanceolate entire leaves; cultivated 
in all warm countries for the sake of the refreshing pulp of its fruit. Flowers usually 
bright scarlet, with a leathery top-shaped calyx divided at the top into 5 or 7 valvate 
lobes; petals as many as the divisions of the calyx and alternating with them, or 
in double-flowered varieties numerous; stamens many, inserted around the mouth 
of the calyx; style long, bent, stigma capitate; fruit usually the size of an apple, 
globose, bearing the persistent calyx, many-celled, containing very many angular 
seeds, with coriaceous testa and watery outer coat containing a pelucid red juice of a 
pleasant acid flavor. A cooling sherbet is made from the juice which is greatly 
appreciated by those living in warm countries. 
The hard rind of the fruit is astringent and in some countries is used in tanning 
and in dyeing. The bark is used asa tan and dye for leather, and the astringent
