THE FLORA OF THE TOWN OF SOUTHOLD, LONG 

 ISLAND AND GARDINER'S ISLAND 



By Stewart H. Burnham and Roy A. Latham 



First Supplemen'tary List 



The preliminary flora was published in Torreya 14: 201-225. 

 Nov. 1914 and 229-254. Dec. 1914. The majority of the 

 enumerated plants were collected in 191 5. Mr. Frank Dobbin 

 of Shushan, N. Y., also visited Orient Aug. 10-15, I9i5. and 

 spent considerable of the time collecting. 



The territory of the region included in this flora lies wholly in 

 the glaciated region. Along the shore of Long Island Sound is 

 the obscure inner moraine of the Wisconsin ice sheet; and from 

 this moraine is an outwash of thin deposits forming sandy 

 plains over the older Pleistocene formation which shows through 

 and in places controls the topography. Some of the beaches 

 and many of the swamps and marshes belong to the Recent 

 epoch. Gardiner's Island lies between the inner and outer 

 moraines of the Wisconsin ice sheet: and being of more rugged 

 topography "seems to have encouraged a more extensive re- 

 working of the" older Pleistocene "deposits by the Wisconsin 

 ice and a greater deposition of" the till sheet or ground moraine.

The authors are greatly indebted to many specialists, who have 

 made it possible to publish the following catalogue of species. 



Insect Galls* 



Andricus cornigerus O. S. — Horned Knot Oak Gall. 

 Asphondylia globosus O. S. — On stems of Helianthus divaricalus. 



* The majority of these galls were named by Dr. E. P. Felt, state entomologist 

 of the State of New York.
