HAMAMELACE^E. 



Xo. 135. Liquidanibar slyrawflua, , L. Sweet Gum or Bilsterd Eastern 

 United States. A large and beautiful tree, with singular star-like leaves, 

 somewhat resembling the maple. It grows in the Atlantic States in rich, 

 low woods ; also in the Mississippi Valley, but not far north of the Ohio. 

 The wood is compact and fine-grained, but not durable. It is a fine 

 ornamental tree, and deserving of cultivation. 



EHIZOPHORACE^;. 



Xo. 136. Rhizopliora Mangle. L. Red Mangrove. South Florida. 

 Commonly a low, spreading tree in South Florida, also in Louisiana and 

 on the coast of Texas. On the Thousand Islands, it attains a height of 

 40 to 60 feet. All the low keys along the coast are covered by this tree. 

 It sends down roots from its germinating fruits, which take root upon 

 reaching the earth, and thus forms an impenetrable thicket like the 

 Banyan tree of India.
