The richest part of tlu; ilistrict lies, however, within the north- 

 ern arch of Grand River and north of a line drawn from Grandville 

 eiist to the River. There arc only about forty plants indigenous 

 to the district covered by this work, which do not occur here. 

 Second to this are the collecting grounds about the lakes in Plain- 

 Held and Cannon. 



Weeds form a conspicuous part of the flora of any comparative- 

 ly well settled district, and especially is this true about a large 

 city. Our flora contains about twenty-three native species which 

 may be considered weeds and seventy which are introduced, chiefly 

 from Fairope. 



Of plants generally called poisonous, we have four — the sting- 

 ing nettle, wood nettle, poison ivy, and poison sumac. 



It is hoped thatall collectors will use the utmostcare in protecting 

 and preserving those plants which are becoming scarce within the 

 <listrict. Experienced collectors who feel the true spirit of the 

 work, do not need cautioning, but the young and inexperienced 

 often need to be restrained in their enthusiasm. A good maxim 

 is: Consider every plant ?y/7'c until it is known with certainty to be 

 abundant. I hope that all persons finding any plant not mentioned 

 in this Catalogue, or new stations for plants marked rare, local, 

 scarce, or infrequent, will kindly report such at once to me.
