SOME ADDITIONS TO DR. FUSSELL'S LIST OF 

 DELAWARE COUNTY PLANTS.^ 



. BY FRANCIS W. PENNELL. 



In the following paper I have attempted to give a few 

 plants of Delaware County, additional to those recorded in 

 Dr. Fussell's comprehensive list of three years ago. These 

 plants have come to my observation especially in the course 

 of botanizing tramps in the townships of Middletown, Aston 

 and Concord. Occasionally the results of herbarium study 

 have been given. 



A number of the plants recorded are doubtless accidental 

 omissions, a number due to dififerent understanding of old 

 genera, while a larger number are strictly new records to the 

 county. Of the last, while some are native, most are intro- 

 duced plants, seldom seen, perhaps weeds of the future, the 

 first arrival of which is worth recording. 



Most of the newly recorded species are represented by spe- 

 cimens placed in the herbarium of the Philadelphia Botanical 

 Club, at the Academy of Natural Sciences, Philadelphia. 

 The species were mainly determined there, and where herba- 

 rium results have been given they are based upon specimens 

 either in the Club or Academy collections. 



The nomenclature followed in this paper is that of Brit- 

 ton's Manual, Second Edition, 1905. This is the same as 

 that of Dr. Fussell's list. In cases of difference, the nomen- 

 clature of Gray's New Manual, Seventh Edition, 1908, has 

 been added in brackets. 



With each record has been given such matter of habitat, 

 local range and comparison with allied species, as may be of 

 interest. 



Among the plants doubtless accidentally omitted from Dr. 

 Fussell's list are the following : —
