272 Additions to "East Bor. Flora," by Mr. A. Brotherston. 



Kelso ; ditchside, Angryflat, Kelso. This, like others of the 

 nigricantes, is very variable ; no two plants that I have seen are 

 alike in every respect ; they differ both in habit and in the 

 form and clothing of the leaves. 



Salix Damascene, Forbes. Near Carham. Possibly the same as 

 S. Andersoniana of " East Bor." (I have not examined it), they 

 being nearly allied and having glabrous capsules. Besides, 

 these two were not distinguished in " Eng. FL," the nomen- 

 clature of which was followed in " East Bor." 



Potamogeton poltgoistifolius, var. linearis, Syme MS. Plen- 

 tiful in the old pond at Muserig. This is a most peculiar 

 looking variety; many of the linear, submerged leaves are 

 upwards of two feet in length. It was determined by Dr. 

 Syme. He says, " The Potamogeton is one that up to this 

 summer [written February, 1875] puzzled me. I had it first 

 from Mr. A. G. More, from Galway, the year before last, and 

 then supposed it to be P. sparganifolius, Laest., a narrow- 

 leaved form; then Mr. More sent it from Killarney, and I 

 thought it most like P. variifolius, Thor. But last summer, Mr. 

 More got a friend of his (Mr. Barrington) to send me fine 

 specimens from Killarney, in flower (all I had seen before 

 were without flowers or fruit), and it turned out to be a variety 

 . of P. polygonifolius. I have not yet seen the fruit of it, and 

 should much like to do so," 



"It differs from both P. sparganifolius and variifolius { in 

 having the stem unbranched, i.e., there are no side-shoots with- 

 out flowers, and having nothing but submerged leaves ; and 

 the peduncles and flowers are quite similar to those of ordinary 

 P. polygonifolius. The main stem creeps at the bottom of the 

 water and sends up simple (or forked) stems— when the stem 

 forks, each branch commonly produces floating leaves." 



„ nitens, Web. This very rare species is abundant in 



the Tweed below Kelso. I have found it on both sides of the 

 river. It is very likely to occur upwards also. 



Caeex filipormis, L. Abundant in Lurgie Loch ; and, to judge 

 by the habit and leaves only, it is also plentiful in Primside 

 bog, Roxburghshire, but of this I am not quite certain. Dr. 

 F. Douglas— who, along with Dr. Clay and Mr. W. B. Boyd, 

 discovered it in Learmouth bog, Northumberland, eight years 

 ago, which is the only recorded station for this plant in the 

 district* hitherto (" Proa," Vol. v., p. 303)— could not find it 

 on a subsequent visit, and he believes that it is now extermin- 

 ated by drainage. The total disappearance of this and several 

 other interesting bog plants from this district appears to me to 

 be only a question of time. Last year (1874) very few of the 

 Lurgie Loch plants threw up flowering stems, and I have never
