Shrub or tree, sometimes as much as 15 meters high, with a trunk a meter 

 in diameter, but usually much smaller, densely branched ; bark thin, smooth, 

 brown ; leaves about 20 cm. wide, very thick, the veins often red ; flowers 

 white ; fruit purple, 1 to 2 cm. in diameter, in long dense heavy racemes ; 

 wood hard, dark brown, taking a good polish, its specific gravity about 0.96.

In Florida and the British West Indies the plant is known as " sea-grape." 

 " pigeon-wood," " horsewood," and " hopwood." The wood is highly esteemed 

 in tropical America for cabinet work, and is used also for fuel. It is said 

 to yield a red dye. The roots are astringent and have been employed as a 

 remedy for dysentery. The fruit is edible, with an acidulous, somewhat as- 

 tringent flavor, and in the West Indies it has been fermented, with sugar, to 

 produce an alcoholic drink. Febrifuge properties are attributed to the bark. 

 The shrub is often planted (as in Florida) for ornamental purposes, for the 

 large thick leaves are of striking and handsome appearance. It grows readily 

 from cuttings. 



The first account of the plant, probably, is that given by Oviedo (Lib. VIII, 

 Cap. XIII), who says: "The Christians give the name uvero to the tree the 

 Indians call quiabara. This is a fine in^. with good wood, especially for mak- 

 ing charcoal for blacksmiths and silversmiths; as they are trees with spn-ad- 

 ing tops, and not straight, although the branches are thick and the wood 

 strong, they are useless for construction of houses, but may be employed for 

 butchers' blocks and shoe lasts. The wood resembles that of madroilo, for it 

 is red, but it is stronger. The fruit consists of tlrn racemes of grapes, sepa-
