and leaving these out of consideration, together with the species of 

 CyperacccB and Graminccc, for, at the time of my visits, owing to their 

 immaturity, few but the most famiHar species of these orders were to 

 be recognized, we find nearly one-third of the indigenous Flora to be 

 different from that of the region with which it is compared. 



Reversing the comparison it appears that of over three hundred 

 indigenous Phanerogams which, in the less elevated region, come 

 into flower prior to the end of June, nearly two-thirds were not 

 found in the Catskills. Not having visited any bodies of water 

 in the latter region, restricted aquatic species have not been allowed 

 to figure in the enumeration. 



Among the characteristic plants of the Catskills, such northern 

 species as most of the following occur, many in abundance : Coptis 

 trifolia Salisb., ActcEci spicata rubra Michx., Dicentra Canadensis 

 DeC, Arabis perfoliata Lam , Viola rotimdifolia Michx., and V. Cana-
