Additional List of Plants not recorded in the "Natural 

 History of the Eastern Borders. " By Andkew 

 Bkothekston, Kelso. 



In the following list, besides the aliens, there are several 

 natives — fine acquisitions to the district; — and I am con- 

 vinced that if members would work up the critical plants 

 in their several localities, many more could be added. No 

 one except those resident in any locality can adequately 

 examine the critical plants in it ; as many of them require 

 to be had in various stages, and at different periods of the 

 year, which cannot be done on an occasional visit. The 

 genera and species most requiring examination are : — The 

 Batrachian Ranunculi, of which we have many forms ; 

 Fumaria ; Viola ; Poly gala ; Rubus fruticosus ; Rosa, 

 especially R. canina, the varieties of which are very little 

 known in this district, although we have several of them ; 

 Callitriche ; Hieracium ; Arctium ; Mentha ; Atriplex ; 

 Salix. The Eastern Borders are particularly rich in Willows. 

 Besides those in this and in a former list, I have found 

 several others not recorded for the district ; but they are not 

 yet satisfactorily determined, not being got in the different 

 stages necessary. Amongst them I expect to have S. 

 triandra, decipiens, laurina, more varieties of nigricans 

 (one of them typical cotinifolia), and ambigua. This is a 

 grand district for the Pondweeds, and they are far from 

 being well known in it as yet. Carex, Bromus (Serrafcdcus), 

 and Chara (a very little known family) ; and perhaps a few 

 others might also be profitably looked up. 



RANTnsrcTTLUS ploeibundus, Bab. This form is not uncommon in 

 this district, both in the Tweed and in ponds ; it grows also in 

 the pool at the Todcrags, near Yetholm, inteimingled with 

 Slum inundatum. There are others of the peltatus group, but it 

 is difficult to name them, as they run into one another. 



„ tmcophylltjs, Chaix. Plentiful in the under pond 



at Spylaw, near Kelso. 



Ftjmaria pallidiflora, Jord. On the edge of a gravel-pit below 

 Galashiels. 



Babbarea intermedia, Boreau. Hayfield at Berryhill (1872) J 

 introduced with the grass seeds. 



Melilotus aevensis, Wallr. Several places on Tweedside, and 

 on cultivated ground about Kelso. I suspect this will be fre- 

 quently overlooked as officinalis ; the habit and general appear- 

 ance being very much alike, especially up till about August
