In the vicinity of habitations several introduced species 

 have escaped to a considerable extent, such as Saponaria 

 officinalis L. and EupJiorbia Cyparissias L., both of which 

 are particularly abundant in and around the old cemetery. 



In connection with the bare sands we may note two quite 

 well defined plant formations : that of the beach and that of 

 the dunes. Ammodenia peploidcs (L.) Rupr., Cakile edentida 

 (Bigel.) Hook., Lathyrus maritimus (L.) Bigel., Euphor- 

 bia polygonifolia L., and Xanthium echinatum Murr., are 

 typical beach species, which are capable of becoming estab- 

 lished in the pure beach sand, down to the very edge of 

 high-water mark. Mixing with the inner border of this vege- 

 tation is Salsola Kali L. and Solidago sempervirens L., and 

 then begins the typical dune flora, in which Ammop/iila are- 

 naria (L.) Link, is the most prominent element. Associated 

 with this are occasional large patches of Hudsonia tomentosa 

 Nutt., clumps of Myrica Carolinensis Mill., and Primus mari- 

 tima Wang., and in less abundance but more widely scattered, 

 Cyperus Grayi Torr., Polygonella artiadata (L.) Meissn., 

 Lechea maritima Leggett, Onagra Oakcsiana (A. Gray) 

 Britton and Artemisia caudata Michx. In low-lying, wet 

 areas, such as at the head of Race Run, this merges into 

 a characteristic sub-formation, consisting largely of Juncus 

 Grecnii Oakes & Tuckm., J. Canadensis J. Gay, Scirpus 

 Americanus Pers., and Salicornia hcrbacca L. and when 

 such areas become converted into fresh-water swamps these 

 species are replaced by Elcocheiris ovata (Roth.) R. & S., 

 E. aciadaris (L.) R. & S., Fimbristylis autumnalis (L.) R. 

 & S., Xyris Carolinieina Walt., Eriocaulon scptangidare
