AMERICAN FOREST TREES 



OTHER SPECIES. Two other trees of this country are called mangrove though 

 they are not even in the same family. One is the black mangrove (Avicennia nttuiaj, 

 called also blackwood and black tree. It is a Florida species of the family Verbenacea, 

 and has some of the mangrove's habits. It takes root and grows on muddy shores 

 and is a land builder. The largest trees are sixty or seventy feet high and two in 

 diameter, but are usually less than thirty feet high. The bark is used in tanning, and 

 no use for the wood is reported, except for fuel. White mangrove (Laguncularia 

 racemosa), known also as white buttonwood, is a Florida species. It attains a height 

 of thirty or forty feet and a diameter of a foot or more. It reaches its largest size 

 on the shores of Shark river, Florida. The wood is dark yellow-brown, and the bark 

 is rich in tannin, and the tree may become valuable as a source of tanbark. 



Near akin to white mangrove is Florida buttonwood (Conocarpus erecta) 

 which is highly esteemed as fuel. It burns slowly like charcoal. Trees are from 

 twenty to fifty feet high. Its range lies in southern Florida. Black olive tree 

 (Terminalia buceras) belongs in the south Florida group, and the wood is exceedingly 

 hard and heavy. The trunk is often two or three feet in diameter, but lies on the 

 ground like a log, with upright stems growing from it. Tanners make use of the bark.
