Gilman (1957) follows the nomenclature of A. S. Hitchcock's Manual 
of the Grasses of the United States. Whenever the nomenclature used 
conflicts with that of The New Britton and Brown Illustrated Flora 
(Gleason, 1952), the names from the latter are given in parentheses. 
Common names of species given by Gray's Manual are placed opposite 
the scientific names. Additional common names used by residents of the 
vicinity of the Chesapeake Bay Center are distinguished by the letter 
"(L)," for "local," or are listed separately in Appendix III. 
Annotations 
The ecological annotation which accompanies each species has five 
categories: the general location (Java Farm or Ivy Neck), the estimated 
abundance of the species, its exact collection site or specific habitat, 
the dominant or canopy species of the collection site, and some of the 
associate species observed in the same location and stratum. 
The estimated abundance of an entry indicates the ease or redis-— 
covering that species in the field; the four categories are: 
Abundant (plentiful throughout the habitat) 
Moderately abundant (evenly distributed but not plentiful) 
Infrequent (thinly scattered) 
One station (a single plant or very small, compact group) 
The last category is preferred to "Rare" or "Local" because the 
Center has not yet been studied in sufficient detail to permit a safe 
assumption concerning the restriction of distribution of species. 
Additional annotation data are being sought and are listed in Appendix II. 
When the checklist is revised a more precise evaluation will be made.
