NOTES ON THE FLORA OF CENTRAL AND 

 SOUTHERN DELAWARE 



By Charles S. Williamson 



So little is known of the flora of central and southern Dela- 

 ware, that the following notes on specimens collected by members 

 of the Philadelphia Botanical Club, during the summers of 1907 

 and 1908, may be of interest. 



The first tnp was taken by Messrs. Brown, Van Pelt and B. 

 Long on September 21, 1908. Its purpose was to find a good 

 location for the Symposium of 1909. The vicinities of Townsend 

 and Millsboro were visited. 



The Symposium was held at Georgetown, July 4 to 9. The 

 attendance was very small, there being at no time more than five 

 and on the first and last days only two botanists present. There 

 were no formal meetings, but many interesting plants were found. 



The afternoon of July 4 was spent on " the Hammock," about 

 two miles east of Georgetown. 



Other botanizing grounds visited in the vicinity of George- 

 town were, Morris Pond, a large mill dam about eight miles east 

 of our headquarters, Milton and the salt marshes beyond. Laurel 

 and Bethel, Rehoboth, and Ellendale. 



On July 20 Messrs. Van Pelt and Long visited Milford and 

 Ellendale and collected many plants that had been overlooked 

 or that were not in bloom on July 9. 



On August 20 the same gentlemen, with Mr. E. B. Bartram, 

 made a trip to Middletown and Smyrna, hoping to find Alnus 

 inaritima within the club limits. In this they were not successful, 

 but they did find several plants that were new to the herbarium. 



Finally, on August 29 I revisited several of the localities at 

 which we had collected during the Symposium. 



Pinus Strobus L. Rare, observed only east of Milton.
