Salix discolor Muhl. Glaucous Willow. This form has been omitted 

 from the 1911 Report. In Coulter's Catalogue it is reported from Tippe- 

 canoe (Cunnington) ; Jefferson (Barnes) ; Vigo (Blatchley) ; Kosciusko 

 (Coulter) ; Clark (Baird and Taylor) ; Gibson and Posey (Schneck) ; 

 Knox (Spillman); Hamilton (Wilson); Steuben (Bradner). It is more 

 or less abundant in White County. Specimens were taken in Monon 

 and Honey Creek Townships. 



Salix humilis Marsh. Prairie Willow. This willow is not included 

 in the 1911 Report, nor is it mentioned in Hough's Handbook of the 

 Trees of the Northern States and Canada. The range for Indiana as 

 given in Coulter's Catalogue is as follows: Laporte (Barnes); Putnam 

 (MacDougal) ; Vigo (Blatchley) ; Tippecanoe (Coulter) ; Hamilton (Wil- 

 son) ; Steuben (Bradner). 



In this, as in many other instances, the attention is drawn to the 

 number of well-worked counties. It occurs in Honey Creek Township 

 and is very likely in other townships. 



Populns ireniuloides Michx. American Aspen, Quaking Asp or 

 Aspen, 1803. The Quaking Aspen is a very familiar tree in White

Populus deltoides Marsh. Cottonwood, Necklace Poplar. (P. caro- 

 linensis Moench. 1785; P. monilifera Ait. 1789; P. angulata Ait. 1789.) 

 This is a much larger tree than the Quaking Aspen. Common through- 

 out the county. Said to consist of several races. 



Populus gvandidentata Michx. Large-toothed Aspen. Scattered 

 throughout the county in low, rich soils, or near the edges of sand ridges. 



Populus alba L. White or Silver-leaf Poplar. Introduced from 

 Europe. Escapes in all parts of the State, although the published rec- 

 ords are meagre. Escapes in several places in White County. Speci- 

 mens were taken from trees along Big Creek about four and one-fourth 

 miles east of Chalmers.
