87. Planera aquatica ( Walt.) J. P. Ginelin. 



Planer-tree. A small tree much resembling an elm, found in the swamps of 

 the southeastern part of the State. It has a smooth angled trunk and the wood is 

 soft and light. Found only in Dunklin and New Madrid counties. 



88. Celtis Mississippieusis Bosc. 



Yellow hackberry. A small- sized tree found along the bottoms of the larger 

 streams, and having a smooth trunk with warty pieces scattered over it. The 

 wood is of a beautiful yellow color and is quite soft and very easily split. As 1 

 understand the species it is found in Butler, Cape Girardeau, Clay, Dunklin, Jack- 

 son, McDonald, Mississippi, New Madrid, Shannon, St. Francois, St. Louis, Stod- 

 dard and Wayne counties. 



89. Celtis occidentalis L. 



Hackberry . A large valuable tree, reaching its greatest development along the 

 Missouri river in the central and western part of the State. The woed is white, 

 very hard and almost uncleavable, and the bark has a peculiar hacked appearance. 

 It occurs in Adair, Atchison, Buchanan, Cape Girardeau, Cedar, Clark, Clay, 

 Daviess, Dunklin, Holt. Howard, Jack3on, Madison, McDonald, New Madrid, 

 Oregon, Pike, Ray, Ripley, Scotland, Shannon, St. Francois, Si. Louis, Stoddard, 

 Washington and Wayne counties. 



90. Celtis accidentalis putnila (Pursh) A. Gray. 



Low hackberry. A low shrubby species of hackberry, commonly considered as 

 a variety of the last, but I think it would be better to place it with Celtis Mississip- 

 piensis. It is found along rocky river banks, mostly in the southern part of the 

 State. It has been fonnd in Howell, McDonald, Newton, Oregon and St. Louis 

 counties. There is a Celtis in the southwestern part of the State that maybe a 

 new species, but I have been unable to get sufficient material to determine this. 



MULBERRY FAMILY (Moraoe^e). 



91. Moras alba L. 



White mulberry. Commonly planted for ornament, and formerly for feeding 

 silk-worms, and has become adventive, according to Tracy. 



92. Moras rubra L. 



Mulberry. A common, well-known, small-sized tree, which is distributed 

 pretty much all over our borders, and which reaches its greatest development in the 

 southeastern part of the State, where trees are frequently met with that are three 

 to four feet in diameter. It occurs in Atchison, Bollinger, Butler, Cape Gir- 

 ardeau, Carter, Clark, Clay, Dade, Daviess, Dunklin, Holt, JacksoD, Jefferson, 

 Lawrence, [Madison, McDonald, Newton, Oregon, Pike, Platte, Ray, Ripley, 

 Shannon, St. Francois, St. Louis, Stoddard and Wayna counties. 



93. Broussonetia papyrifera L'Her. 



Paper mulberry. A fast-growing tree, commonly planted for shade in towns 

 in the lowlands of the southeastern part of the State. The soil and climate are so 

 congenial)to its nature that it easily escapes from cultivation, and is found growing 

 in many places naturally. I have observed it only in Dunklin county. This tree is 

 not quite hardy enough to stand the severe winter we have in Jackson county, but
