BOTANICAL NOTES AND NEWS. 



Juneus tenuis, Wild., in Perthshire. In July last I came upon 

 a quantity of this rush on the bank of the Tay at Deny Island about 

 four miles below Perth. It was growing in a sort of rut worn by 

 the feet of the fishermen who haul their nets a short distance off. 

 There were clumps of it growing pretty thickly along this rut for 

 about twenty yards. It did not intermingle with the native vegeta- 

 tion, which, however, bordered it closely on either side. There was 

 so much of it, and it was growing so vigorously, that I can hardly 

 believe it to be the growth of a single year, but I am confident that 

 it has not been there more than two or at the most three years. 

 Derry Island is a place where casuals brought by the river are prone 

 to lodge ; and indeed along the bank of the Tay between Perth and 

 it several aliens have become naturalised, e.g. Aster Novi-Belgii 

 (in great beds), Rudbeckia laciniata, Astrantia major, Solidago 

 lanceolata. There is no cultivated ground very near at hand, and 

 it would appear that seed must have been brought to the spot by the 

 river, though from what place I am quite unable to say. The rut 

 occupied by the plant is within the reach of high tides and floods, 

 and must have been during the present season repeatedly sub- 

 merged ; but the plant seemed to thrive under the process, as many 

 of the flowering stems were over two feet long. From this 

 submerging, or from the persistent wet weather, it probably resulted 

 that about half of the flowers were barren, as I found when gathering 

 the plant later in the season. 



Mr. Arthur Bennett, to whom I sent specimens for corrobora- 

 tion, forwarded to me a few weeks afterwards a specimen of the same 

 rush gathered in the beginning of September by Miss Eleanora 

 Armitage in Glenfalloch. In response to a request for particulars 

 regarding it, Miss Armitage writes : " I found the plant, looking 

 quite native, by the side of the road which goes down Glenfalloch 

 from Crianlarich, about three miles, as far as I can remember, 

 below that place. It was on the right hand side of the road along 

 the grassy edge, beyond which was boggy grass land. The soil was 

 moist from trickling water, and the plants grew in colonies along a 

 short space of the road, rather by themselves than mixed with 

 herbage, except of mosses and hepatics ; but grasses and various 

 herbs grew quite near it, and it certainly looked quite at home. 

 It was not near the Falloch river." Judging from the specimen 

 I have seen, the plant was not nearly so tall and luxuriant in 

 Glenfalloch as on Derry Island. In the latter station it is certainly 

 not native, and I should with great difficulty be brought to believe 

 that it is anything but a very recent introduction in Glenfalloch.

Arising from this finding of Juneus tenuis in Glenfalloch, Mr.
