Penneil, F. W., Flora of the Conowingo Barrens of South- 

 eastern Pennsylvania. (Proc. Acad. Nat. Sei. of Philadelphia 

 1910. p. 541—584.) 



This paper considers the flora, climate, physiography and soils 

 of the Serpentine barrens found in Delaware and Chester Co. 

 Penna. and along the Maryland State Line. An analysis of the 

 elements is given with reference to their distribution on the dif- 

 ferent, quite separate Serpentine outcrops which exist as distinct 

 islands of xerophj^ic plants surrounded b}^ a mesophytic forest Ve- 

 getation upon the richer mellow agricultural soils. The affinities of 

 the flora are described and a list of 217 species which are restricted 

 to the barrens, are common to the surrounding country, but much 

 more frequent on the barrens, or are frequent on Conowingo 

 Barrens, but much less common than in the surrounding district 

 is appended, as also a list of 77 occasional species of the Cono- 

 wingo Barrens, mostly stragglers from the surrounding flora and 

 7 species that are introduced. John W. Harshberger.
