List of Tweedside Plants, by Mr. A. Broth erston. 137 



Luzula nivea, Desv. Occasionally in pastures in this neighbour- 

 hood, to which most probably it has been introduced with 



Potamogeton FLABELLATUs (?) Bab. Yetholm Loch. 



*Festtjca ambigua, Le Gall. Sides of Gala. There were many 

 plants of this, July, 1873. From Mr. Stewart's paper I observe 

 that P uniglumis was not uncommon in the same district in 

 1868, none of which I picked up last year. There is very little 

 chance of confounding these two species. The larger glume 

 of uniglumis being about the same length as the lowest flower, 

 while in ambigua it is about one-third ; which was the propor- 

 tion in the Gala plants. 



*Serrafalcus patulus, Pam. Tweedside, Kelso. 



* ,, sqttarrosus, Pam. Gala, near mouth. 



* ,, secalintts, Bab. Tweedside, from Edenmouth to 

 Gala ; plentiful, 1873, There were three very distinct varieties 

 — with several intermediate forms — and all equally plentiful, 

 viz. : — Bromus secalinus (Parnell, 49 and 121), B. vulgaris 

 (Parnell, 122), and one awnless altogether. I can find no 

 notice of this variety in any book that I have access to ; but 

 there is a very good drawing of it in Lowe's "Brit. Grasses," 

 pi. liv,, but the description is of the typical form. 



Lolium temulentum, L., var. longiaristatum, Pam, Many 

 plants in the bed of the Gala. 



Besides the above which, so far as I am aware, are new to 

 the district (excepting the typical S. secalinus and Lolium 

 temulentum), I saw the following on the river side, in addi- 

 tion to those which were in my last year's list : — 



^Erysimum orientale, B. Br. From Kelso to Gala, and in a 



garden at Forest Field, Kelso. 

 *Sinapsis nigra, L. Plentiful from Eden to Gala. 

 *Eeseda lutea, L. Near mouth of Gala. 

 *Xanthium spinosum, L. Kelso to Gala. 

 *,Setaria viridis, Beauv. Do. 



And several undetermined species. 



The Mimulus named M. guttatus (?) in " Proceedings " for 



1872, p. 439, is a spotted variety of M. luteus. 



I have no doubt that by a careful search many more 

 introduced plants could be picked up on Tweedside. Many 

 of them have taken kindly with the change and are self- 

 supporting, some of them displacing the aboriginal possessors 

 of the soil ; but a few of the more tender species require 

 fresh importations of seed to keep up the stock, as they do 

 not ripen their seed here.
