SALIX ANDERSONIANA X HERBACEA? 



Syn. S. semireticulata B. White, pro pte., Eevision, 444. 



Exs. Hb. B. White, No. 402. E. F. & W. E. Linton, No. 107 ? 



A dwarf trailing shrub, much resembling some forms of S. her- 

 bacea x lapponum, but with the leaf-blades more serrate (the 

 teeth with small cartilaginous points) and inclined to blacken in 

 drying, and the pedicels of the ovaries in an early stage as long 

 as, and at length exceeding, the linear or linear-oblong nectaries, 

 the lower ones sometimes twice as long or more. 



Dr. B. White's No. 402 is minutely described by him (I. c. 

 pp. 444-445) ; the specimens show even longer pedicels than he 

 describes, an important character favouring the S. Andersoniana 

 parentage. This plant is described under B. White's name, p. 68. 



The other plant, Linton, No. 107, is somewhat similar, but has 

 the leaf-blades more regularly serrate, the bracts rather more 

 broadly obovate, and the well-developed pedicels 2-3 times as 

 long as the linear-oblong nectaries. The pedicels and oblong 

 shape of the nectaries seem to show that this is not S. herbacea 

 X lapponum, the only alternative. 



The latter plant is from Glen Fiagh, Forfarshire ; the former 

 from Meall Ghaordie, Perthshire. This hybrid is endemic to 

 Scotland.

 (from Meall Ghaordie, and from Barvic Burn, near Crieff, as S. 

 nigricans). E. F. & W. E. Linton, Nos. 24, 74, 102. Enander, 

 Nos. 62, 63, 65-70, 72, 73-79. Hb. W. E. Linton, Nos. 69, 92, 96. 



A variable hybrid, in foliage and catkins ; usually a dwarf shrub. 

 S. Andersoniana is shown in the greater pubescence and duller 

 colouring and blackening in dried specimens of the foliage ; in the 

 broader and more foliaceous stipules ; in the partial or total 

 glabrescence of the ovaries, and in the longer pedicels. The 

 influence of S. myrsinites appears in the leaf-blades being + glossy 

 on the upper surface, and not blackening much, the lower ones 

 being usually green and ± shining beneath, their nerves often 

 opaque and their reticulation marked ; the stipules, too, being 

 green beneath and showing some lustre. In the catkins the 

 anthers are tipped with red or crimson, the ovaries + pubescent, 

 the styles tinged with red-purple, owing to the same influence of 

 S. myrsinites. 



S. Andersoniana x myrsinites is usually a dwarf shrub trailing 

 over damp rocks, rather frequent in Glen Fiagh, found also in 

 Glen Doll, Forfarshire ; in Perthshire it occurs on Ben Laoigh, 

 Meall Ghaordie, Craig Mhor (head of Glen Lochay), and on the 

 lower rocks of Meall nan Tarmachan above Lochan na Lairige ;
