Species imperfectly naturalized. — Lepidiumruderale,Ileseda 

 lutea^ a chalk plant; Melilotus alba, (Enothera biennis, "from 

 North America;" Solanum nigrum, Cynoglossum officinale, 

 Salsola Kali, Mercurialis annua, Phalaris canariensis, and Gly- 

 ceria rigida. — Of these ten, seven are recorded by Mr. Winch, 

 in his Flora, published in the Transactions of the Natural History 

 Society, in 1832. But, although they still attract the notice of 

 the botanist, the frequency of their presence among us is owing 

 chiefly to their repeated importation among ballast. 



The total number, therefore, of species ascertained to grow 

 within the given circle, embracing an area of seventy-eight and 

 a half square miles, is 585. And, if to these we add some species 

 of the genera Ruhus, Salix, and Rosa, and a few others, which 

 future examinations of the ground will probably bring to light, 

 620 species will doubtless be found as a pretty close approxima-
