974 REPORT OF STATE GEOLOGIST. 



A. junceus Ait. Rush Aster. 



Reported, so far as I am able to discover, only from Clark 

 County by Baird and Taylor. The station was a back-water 

 slough, where the plant was found in abundance. 



A. Novi-Belgii L. New York Aster. 



A swamp aster of limited distribution in our area. In Clark 

 County it was found at the same station and associated with 

 A. junceus. 



The species was collected in flower August 3, which is the only 

 fact bearing upon its flowering season. 



Clark (Baird and Taylor); Noble (Barnes). 



A. longifolius Lam. Long-leaved Aster. 



This extreme northern form was collected by Dr. Charles R. 

 Barnes in August, 1878, in Noble County, where it was growing 

 in a peat bog. The herbarium specimens justify the reference, 

 while the number of northern forms found in Noble County 

 affords collateral evidence of the probability of its occurrence. 

 It has not been reported since the above date. A citation of the 

 occurrence of the form in Clark County is doubtless an error. 



A. ptarmicoides (Nees) T. and G. Upland White Aster. 



"Dry sands. Pine Station, Lake County." (E. J. Hill.) This 

 was the only record for the State until 1894, when Messrs. Conner 

 and Laben collected it at Happy Hollow, Tippecanoe County. 

 A comparison of the Tippecanoe plant with the type specimens 

 in the Gray herbarium verifies the orignal determination. At 

 this station the plant was found on a dry ridge of fine gravel. 



A. dumosus L. Bushy Aster. 



In dry, sandy or gravelly soil. Frequent along railways and 

 roadsides, rarely found in shaded places. 



Flowers in September and October. 



Tippecanoe (Young); Monroe and Yigo (Blatchley); Noble 

 (Yan Gorder); Jefferson (J. M. Coulter); Clark (Baird and Tay- 

 lor); Jay, Delaware, Randolph, and Wayne (Phinney); Gibson 

 and Posey (Schneck),
