cuius Lingua grows in bogs which surround the loch. The other 

 rare species here are Pyrola rotundifolia, Scutellaria galericulata, 

 Lycopus europceus, Typha latifolia, etc. ; but recent drainage has 

 caused some of these to disappear. 



Note. — Sisymbrium Irio still grows on the wall of Berwick, 

 but most abundant at the pier gate. 



ADDENDA TO THE FLORA OF HARROW. 



About twelve months ago we presented our readers with a list 

 of plants occurring in a wild state in the neighbourhood of Har- 

 row. Since that time we have been enabled to add considerably 

 to our own knowledge of the local Flora, and proceed to lay the 

 results before the public. About 151 Flowering Plants, 5 Ferns, 

 3 Horsetails, and 3 Chara have been discovered. Some little 

 way has also been made towards preparing a list of the Mosses, 

 Hepatica, Lichens, and Fungi of the district. This result is 

 owing partly to the extending of our search over a wider field, 

 and partly to a closer examination of the same ground searched 

 last year. The localities in which the plants have been found, 

 and which are indicated by abbreviations in the last column of 

 the list, are as follows : — Alperton, A. ; Eastcot, E. ; Greenford, 

 Gf.; Harrow, H. ; Harrow Weald, HW. ; Northolt, N. ; Oxhey, 

 Ox. ; Pinner, P. ; Roxeth, R. ; Ruislip, Rp. ; Stanmore, S. ; 

 Wembley, W. ; and Wood End, WE. 



Our Harrow Flora now assumes a respectable appearance, 

 containing in all, of Flowering Plants, Fern Allies, and Charce, 539 

 species and varieties, comprised in 260 genera and 73 families. 

 We hope that this list may, by further research, be considerably 

 enlarged. As it is, after deducting a few plants that occur by 

 merest accident, the remainder is sufficiently large to enable us 

 to withdraw the depreciating remarks made last year in reference 

 to the Flora of this neighbourhood. An extensive Flora could 

 not be expected in an inland district, of small extent, nearly all 

 under grass, and having very little variety of soil. Under these 

 circumstances, and considering how large a portion of the neigh- 

 bourhood has never been searched at all, we feel gratified that 

 the results of occasional walks, within a term of two years, should 

 have proved so satisfactory. Our Flora is large enough to afford
