57 Delaware is included because physiographically it is a part of the 

 region here treated. The records for the plants listed were gleaned first 

 of all from the National Herbarium, and from "The Plant Life of Mary- 

 land (Maryland Weather Service, Special Publication III, 1910). The 

 records from these sources are given without further comment. When a 

 local record of a plant was available search was carried no further ; 

 Maryland occurrences were next looked up, and finally Delaware reports 

 on yet additional species were incorporated in the list. The authorities 

 for Delaware records not obtained from the National Herbarium are indi- 

 cated by surnames, the references in full being :
