The Flora of the Cayuga Lake Basin 



W 



A few weeds which were rare in Dudley's time are now common. In 1885 

 Hicracium aurantiacum was known from only three stations, and Lactuca scariola, 

 var. integrata, and Potentilla recta from only one. All of these are now abundant. 

 Very few of the weeds known to Dudley have become extinct, though a con- 

 siderable number appear to have increased little or not at all. For example, 

 Senecio vulgaris and Hibiscus Trionum are found now only in the same general 

 regions as was the case many years ago. Aristolochia Clematitis has not established 

 new stations, though the area of the original station has apparently been considerably 

 increased. A weed as flourishing and as dominant where once established in low 

 grounds as Succisa australis, has in the seventy-five years since its introduction 

 spread over only a few square miles, though it has recently been found near 

 Montezuma village and at Auburn, respectively 12 and 9 miles away.

 escaped from cultivation, but also certain native plants, such as Pycnanthemum 

 flexuosum, which have entered the flora and are behaving as weeds.
