472b. Alayaca auhleti Michx. Auglaize County, A. Wetz- 

 stein. The occurrence of this aquatic species so far north of its

 S. E. Horlacher. Distinguished from Suiilax hcrbacea, which it 

 closely resembles, by the pubescent lower surface of the leaves.

 quently cultivated for ornament and escaped in Wood Countv, 

 where it was collected by Professor Kellerman.

1794a. XantJiium commune Britton. This, our commonest 

 species of Cocklebur, has generally been confused with Xanthiinn

 burs either glabrous or merely puberulent. the hairs never 

 exceeding the diameter of the spines.
