SCROPHULARIACEAE OF THE LOCAL FLORA. I 



By Francis W. Pennell 



In commencing the systematic study of a family of plants for 

 North America there is logic in studying first those species which 

 occur in the eastern seaboard of the United States. These were 

 the plants first known in detail, if not necessarily those earliest 

 discovered, on this continent. From Massachusetts to Carolina 

 we are on classic ground, and here the plant-life has been worked 

 over so many times, and each species so often collected, that 

 we may now speak with certainty of nearly all specific identities. 



The present study is concerned with but a portion of this 

 territory, the counties included within the local flora range, of 

 the Torrey Botanical Club and of the Philadelphia Botanical 

 Club. These combined include all of Connecticut; New York 

 southeast of Columbia, Greene and Delaware counties inclusive; 

 all of New Jersey; Pennsylvania southeast of Pike, Wayne, Lacka- 

 wanna, Luzerne, Schuylkill, Lebanon, Dauphin and Lancaster 

 counties inclusive; Newcastle county, Delaware; and Cecil 

 county, Maryland. This area is in main part represented in 

 the Torrey Club collection at the New York Botanical Garden, 

 and the portion within approximately fifty miles of Philadelphia 

 in the remarkably full and valuable collection of the Philadelphia 

 Club at the Academy of Natural Sciences in that city. To both 

 collections I have had free access, and the records below include 

 data from these, the herbaria of Columbia University, the 

 Brooklyn Botanic Garden, the University of Pennsylvania and 

 several other institutions. To the curators of all I am appre- 

 ciative.
