304 OHIO BIOLOGICAL SURVEY 



confidently believes ^\ill be found, when once the worker becomes famil- 

 iar with it, as far superior to the classification of Engler now generally 

 used as was that to DeCandolle's which it superceded. Those un- 

 familiar with the new arrangement will doubtless experience some in- 

 convenience in using it at first, but that is a ditficulty inherent in any 

 nnprovement. At the end, I have added a Synopsis-summary by which 

 the location of the families may readily be found. 



The nomenclature, following the Ohio list is that of the second 

 edition of Britton & Brown's Illustrated Flora. Recent synonyms have 

 been added where they seemed necessary or desirable to make the list 

 intelligible to all readers. 



The Sugar Grove region is unique for this part of the country in 

 that its flora was worked up by John M. Bigelow*, more than seventy 

 years ago. Bigelow was an able botanist, companion and friend of Sul- 

 livant, for whose ability one finds an increasing respect as he scrutinizes 

 his work. Basing my judgment almost entirely on his remarkable list, 

 I have great confidence in his determinations and have unhesitatingly 

 included most of them in the present list. He found a very large num- 

 ber of very rare plants just on the edges of their ranges or just beyond 

 their present range as we know it, but there are few if any ''wild" 

 reports of species entirely out of range such as one would find in the 

 inaccurate work of a less able man. He lists 871 species and varieties 

 all of which with two exceptions he found growing in Fairfield County. 

 His list includes a number of plants, specimens of which are not now 

 definitely known from Ohio. Most of these have been included on his 

 authority marked "Fide Bigelow." Many of them are plants whose 

 general range is such as to make their occurrence higlil>' jn-obable and 

 others are so distinctive that there could be no question of their proper 

 determination. They are : 



Rammciilns reptans L. "Nfd. to Pa. northwanl and westward." 



Delphinium earolinianum "Va. N. C, and Ga., to Ark., Mo., ^linii., and Sask. " 



Polypola incarnata. N. J. to S. Ont., Wise, Neb., and sonthw. 



Trifolinni reflexum. Included on state list but no Ohio specimens knoAvn to us. 



Lithospermum officinale. A European escape not apparently establishing itself. 



Trisetum pahistre. "Mass. to 111. and southw. " 



Panicularia acutitlora "Me. to Del. w. to Ohio." 



Carex vesicaria. ' ' E. Que. to B. C. s. to Pa., Gt. Lake region, etc. ' '
