FLOWERING PLANTS AND FERNS OF INDIANA. 593 



plantains, especially Plantago major, the creeping spurge, Euphorbia 

 humistrata, and in wet soils, "rich weed." 



Most of these are low growing forms and can not be cut with the 

 lawn mower. The only remedy seems to be the digging up of the 

 individual plants as they appear from year to year, until the lawn is 

 freed from their presence. 



Some roadside weeds, such as the dog fennel, the fetid marigold and 

 some of the coarser verbenas, deserve attention from those in control 

 of highways. 



It will be seen that to the list given by Mr. Blatchley, I add: 



Velvet leaf, Abutilon Abutilon (L.) Rusby. 



Chicory, Cichorium Intybus L. 



Burdock, Arctium Lappa L. 



Dandelion, Taraxacum Taraxacum. 



Mallow, Malva rotundi folia. 



Shepherd's purse, Bursa Bursa- pastor is. 



Plantain, Plantago major. 



Plantain, Plantago Rugelii. 



Creeping spurge, Euphorbia humistrata Engl. 



Rich weed, Adicea pumila (L.) Raf. 



Dog fennel, Anthemis Cotula L. 



Fetid marigold, Dysodia papposa (Vent) Hitch. 



Verbenas, Verbena various species. 



In certain localities some of these may be replaced by other forms, 

 but taking the State as a whole, it is believed that the above list in- 

 cludes all of the universally bad weeds of our area. When the weed 

 problem is reduced to such simple terms there seems no excuse for not 

 having the annoying forms in fair control in all cultivated areas. The 

 forms will probably never be entirely exterminated, for their wide 

 range of adaptation will enable them to secure a foothold wherever the 

 vigilance of the farmer is ever so slightly relaxed. 



NOMENCLATURE. 



Without expressing any opinion upon disputed synonomy, it has 

 been thought best in this catalogue to follow the nomenclature of 

 Britton and Brown's Illustrated Flora of the Northern United States,, 

 Canada and the British Possessions. Where this varies from the Sixth 

 Edition of Gray's Manual, the name used in the latter work is placed 

 in parenthesis. The most marked changes, perhaps, are found in the 

 breaking up of the great families of the Composites, the Leguminosa, 

 the Rosacea, the Ericaceae, the Geraniacece, the Sapindaceae and the
