On a Collection of Willows, by Mr A. Brotherston. 273 



over the specimens in the Herbarium in Berwick Museum, I 

 came upon a sheet which throws some light on the subject. On 

 the same sheet are two young shoots with catkins, and one barren 

 branch showing mature leaves. They were labelled S. Forsteriana 

 and 8. Andersoniana from the above locality, so that there is no 

 doubt that they are from the plant, or rather plants referred to 

 in "Fl. Ber." and "EastBord." The two shoots with catkins 

 are from two different Willows, viz., S. Andersoniana, or some 

 other with smooth germens, and S. Forsteriana, or some other 

 with silky germens. From which it appears that both varieties 

 were growing together, thus accounting for the contradictory 

 records. 



(24) S. anibigua, Ehrh. Many plants of this supposed hybrid 

 — both male and female — between 8. aurita and 8. repens, are 

 growing at Lurgie Loch. Some of them are four feet high, and 

 a good deal more in diameter. Both sexes are also in Primside 

 bog, but are not so characteristic as the Lurgie plants. 



(25) 8. parvifolia, Sm. ? Primside bog. 



(26) S. incubacea, L. ? One of the many varieties or forms of 

 S. repens, which are both plentiful and variable in Lurgie Loch. 

 Neither of these two last exactly fit the description of these 

 varieties, but they are the nearest. 



From p. 180 of the "East. Bord." I quote the following: — 

 " 8. fusca, D. On the links of Holy Island, and on Eoss Links, 

 where it forms patches, in general of a circular form. The plant 

 was considered to be 8- argentea until the error was corrected by 

 Mr Borrer, who saw specimens in the herbarium of Mr Emble- 

 ton." See Trans. Berw. N. Club., ii., p. 122. The error is one that 

 can plead "ancient authority" in apology. With. Bot. Arrang. 

 ii., p. 52. Mr Embleton's plant may have been 8. fusca, but 8. 

 argentea also grows on Eoss Links. Along with the Eev. A. 

 Davidson, I was there in August, 1875, when we gathered both 

 8. argentea ! and another of the repentes which came nearest 8- 

 prostrata. It (the latter) grew in large, mostly circular, patches, 

 but it differed from 8. fusca, which, according to the " Eng. Fl." 

 has the ' ' germen sessile nearly smooth, tapering into an elon- 

 gated style," by having a long pedicel and a very short style. 

 There might have been other varieties of S. repens, but as our 

 time was limited and Psamma Baltica being the chief attraction, 

 we might easily have missed them.
