catalog is to use rather drastic measures. It will be easier to 

 restore names to the list than to continue names whose standing 

 is problematical and serve no purpose except to confuse the plant- 

 geographers and ecologist. So far as the exclusion of foreign 

 weeds and cultivated plants is concerned, if the list is not to 

 represent known herbarium specimens a much larger number of 

 probable species might be added. But it is believed that zeal 

 for accuracy is more commendable than enthusiasm for new 

 records and large numbers. The writer will greatly appreciate 

 information which will tend to establish any species in the fol- 

 lowing hst as a native or introduced Ohio plant:
