148 NOTES ON PERTHSHIRE PLANTS, 



specimens from three different bushes by the R. Lyon, at Fortingal. 

 S. anrita x phylicifolia. Specimens were taken from three bushes of 

 this hybrid near R. Dorchart, Killin ; from a good intermediate 

 example four miles up Glen Lochay ; and from a bush with fruit 

 in Glen Lyon (4 m.). — S. aurita x repens (S. ambigua Ehrh.). 

 Near Fortingal ; and in Glen Lyon (5 m.), where two forms 

 occurred, one intermediate, the other much nearer repens, pre- 

 sumably being S. ambigua x repens. — 8. nigricans X phylicifolia. 



High up the Allt tir Artair, not far below Cam Chreag, Killin ; also 

 near Linn of Campsie. — S. Lapponum L. We saw this (near For- 

 tingal) only in one spot. All the alpine willows fall off greatly in 

 the mountains north of R. Lyon. The northern watershed of 

 Meall Garbh was also poor in willows, owing to absence of cliffs ; 

 but this was not the case with the large watershed north of Ben 

 Lawers. Here we found iihe usual willows of the Breadalbanes, 8. 

 phylicifolia, 8. nigricans, S. Lapponum, S. Arbuscula, and S. her- 

 bacea ; no doubt we should have seen reticulata also, if stormy 

 weather had not abbreviated our exploration. — S. Arbuscula x 

 Lapponum (S. spuria Schleicher). Besides gatherings of this 

 hybrid in the Killin district in known stations, to some of which 

 we were introduced by the Rev. E. S. Marshall, we found three 

 bushes of it in the great watershed N. of Ben Lawers above 

 referred to, two of them in fruit ; and a fourth which may be 

 this plant, but must await the test of cultivation. — S. Arbuscula 

 X nigricans (S. Krcettliana Briigg). When this hybrid was described 

 by one of us in the Journ. Bot. (1891, 214), we were not 

 aware that it had already been named by Briigg ; it is given 

 in the Appendix to Nyman's Conspectus FL Eur. Besides the 

 original station, where one small bush at least still exists, we 

 can now give another, on Ben Lawers, which happily had two or 

 three female catkins in good condition ; there is little doubt, too, 

 that a bush on Craig Loaghane (Meall Ghaordie) is this hybrid 

 also, but it grew out of reach and we have only fragmentary 

 leaf-specimens. — S. Myrsinites L., occurs very sparsely in the 

 Breadalbanes ; besides one or two known stations, we found it, in 

 fruit, in Coire Ardran ; on Meall Ghaordie a fine bush of the 

 variety procumbens Forbes, grew out from the top of a nasty 

 precipice, and near by a small bush of the type.— S. Myrsinites X 

 nigricans Wimm. The nomenclature of this hybrid is* puzzling. 

 Dr. F. B. White adopts 8. WaUenbergu And., after Andersson, who 

 drops S. Myrsinitoides Fr. in 1874, in favour of this latest name. 

 8. punctata Wahl., is probably the oldest synonym, but Wimmer's 

 way of naming it (which is prior to Andersson's) has the great 

 advantage of stating the origin in the name. This we gathered on 

 the Lochan-na-Lairige rocks, near Killin, and also on Meall 

 Ghaordie, both in fruit.— 5. Myrsinites x phylicifolia. The Rev. 

 E. S. Marshall sent specimens, from a smalf bush met with by us 

 on Meall Ghaordie when we were together, to Dr. F. B. White, who 

 considered the plant to be this hybrid ; and we see no reason to 

 question the naming. S. herbacea x Lapponum (S. sobnna F. B. 

 White). Two fine plants, both in fruit, on a low cliff in the
