Salix Andersoniana x arbuscula. 



Syn. S. nigricans x arbuscula Seemen, iv. 235 (excluding 

 S. Kraettliana Briigger). 



Exs. E. F. & W. E. Linton, Nos. 65 ?, 97, pr. pte. {i. e. No. 101, 

 excluding No. Ill, which is doubtful, and may be S. Andersoniana 

 X phylicifolia). Hb. E. F. Linton, Nos. 101 (supra), 137 (?), 139. 



A dwarf shrub, with branches and buds pubescent at first. 

 Stipules 0, or minute on strong shoots. Leaf-blades f-l£ in. long, 

 broadly or narrowly oval, or oval-oblong, narrowed to both ends, 

 serrate or crenate-serrate, pubescent at the very first, usually 

 soon glabrous, + shining and sometimes reticulate above, glaucous 

 or dull green beneath, blackening somewhat when drying. Catkins 

 \-l\ in. long, appearing with the leaves, only $ observed; bracts 

 narrowly oblong acuminate or subobtuse, pubescent, + brown 

 towards the tip ; ovaries ovate-conic rather small, silvery pube- 

 scent, or, in another form, lanceolate, glabrous below, thinly 

 pubescent in the upper half ; pedicels variable, 1-3 times as long 

 as the oblong nectaries, style rather short or long. 



This hybrid is not easy to recognize with certainty. Our 

 plants show signs of S. arbuscula in the small size and glabrescence 

 of the leaf-blades, their shining and + reticulate upper surface, 

 in the suppression of the stipules, in the small ovaries, pale or 

 light brown colour of the bracts, and narrow oblong nectaries. 



S. J. Enander admitted that S. arbuscula is present in Nos. 101 

 and 139, but was of opinion that S. phylicifolia had a share in 

 the composition of both, as well as in the specimens of the triple 

 hybrid following. 



It is very doubtful if S. arbuscula x nigricans has been 

 dectected elsewhere, though it has been reported by Floderus for 

 Scandinavia. Our plants have been found only in the Breadalbane 

 Hills, Perthshire, viz. on Ben Lawers, and on the rocks above 

 Lochan na Lairige low down on Meall nan Tarmachan, more than 

 once in each locality. 



Salix Andersoniana x arbuscula x phylicifolia. 



This is with difficulty distinguished from S. Andersoniana x 

 arbuscula. The chief difference lies in the leaf-blades, which are 

 less blackened in drying and have the tip entire or subentire, as 

 in S. phylicifolia. 



This triple hybrid has been obtained from Meall Taurnie, 

 Sgiath Chrom, and the lower rocks of Meall nan Tarmachan above 

 Lochan na Lairige, all in the Breadalbane Hills, in the neighbour- 

 hood of Killin, Perthshire, and was discovered by P. Ewing. Not 

 known elsewhere.
