HAMAMELACE Zs. - 
No. 135. Liquidambar styraciflua, L.—Sweet Gum or Bilsterd.—Hastern 
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. 
RHIZOPHORAGE Ai, 
No. 1386. Rhizophora 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. 
COMBRETACR Zi. 
No. 137. Conocarpus erecta, Jacq.— White Button Wood.—Florida. A 
small tree of the West Indies and South Florida. It furnishes almost 
the only fuel used in South Florida, and extends north as far as Ancelote 
Keys.—(Dr. Chapman.) 
No. 188. Laguncularia racemosa, Geert.—Black Button Wood.—South 
Florida. Found by Dr. Chapman in South Florida; a small tree 
everywhere; is a mere shrub, except among the Thousand Islands and 
north of Cape Sable, where it forms a large tree. 
MYRTACEZ:. 
No. 139. Hugenia buxifolia, Willd.—Iron Wood.—South Florida. The 
Eugenias are in Florida small trees, reaching 20 to 25 feet in height. 
They belong to the Myrtle family, and the flowers of some species are 
very fragrant. The wood is close-grained, hard, and applicable to cabi- 
net-work.

eaten either raw or formed into preserves. Dr. Chapman found the 
tree extensively naturalized at Tampa Bay, Florida. 
CACTACEZ. 
No. 144. Cereus giganteus, Eng.—Tree Cactus.— Western Texas and Ari- 
zona. The specimens for this order are from Southern Arizona, where 
they are striking and characteristic features of the country. The Cereus 
giganteus grows 50 to 60 feet in a straight column, and finally divides 
into several naked-looking branches. The wood of this and other large 
Cacti presents a singular net-work of fibers in distinct layers.
