970 REPORT OF STATE GEOLOGIST. 



BRACHYCH.ETA T. and G. 



B. sphacelata (Raf.) Britton. FaJse Golden Rod. 

 (JB. cordata Torr. and Gray.) 



Among the forms that have come into the flora from the south, 

 the above is one of the most interesting. Its single reported 

 station is at Clifty Falls in Jefferson Connty. The station 

 abounds in exceptional forms, seeming for some reason to have 

 served as a refuge for plants out of their usual range. The 

 history of the plant is given in full in Proceedings of Indiana 

 Academy of Science for 1895, pp. 189 and 190. 



BOLTONIA L'Her. 



B. asteroid es (L ) L'Her. Aster-like Boltonia. 



In low, open prairies and pastures, in moist, rich soil. Found 

 chiefly in the southern part of the State, but not common in any 

 of its stations. 



Flowering season, from August through October.
