evidence of the presence of S. myrsinites as the above, but was 

 believed to be the triple hybrid by F. B. White as well as the 

 editors of the Set.

An erect bush, 4-7 ft. high, with rather slender branches, 

 pubescent at first, at length glabrous ; buds shortly oval, hairy, 

 glabrescent. Stipules broadly J-cordate, tips usually acute, much 

 laterally twisted. Leaf-blades 1-2 in. long, oval to oval-oblong or 

 -obovate, hairy at first, green and + glabrescent above, rather 

 densely hairy, dull green or glaucous beneath, gradually glabres- 

 cent. Catkins coeval or preceding the leaves, fl. April-May ; 

 bracts lingulate or obovate, moderately hairy ; ovaries glabrous or 

 pubescent, or in a Dumfriesshire form glabrous below the middle, 

 the upper half and the pedicels (which much exceed the nectaries) 

 being pubescent ; styles long or of medium length, stigmas rather 

 small. 



The plant issued in the Set of British Willows, No. 57, as 

 S. aurita x myrsinites x nigricans perhaps ought to be referred 

 here, as S. aurita and S. Andersoniana (S. nigricans) are the most 

 evident constituents ; the glossy upper surface of the leaf-blades and 

 their coriaceous texture suggest a strain of S. myrsinites, and the 

 raised reticulation on the surface of some of them and their texture 

 recall S. arbuscula ; but the catkins show no trace of either. 



S. aurita x Andersoniana is a rare hybrid, recorded for 

 N. Yorks, Dumfriesshire, Berwickshire, Mid-Perth, and the Clova 

 Valley, Forfarshire. Distribution in Europe unknown to me.

Like S. aurita x Andersoniana generally, but showing evi- 

 dence of S. phylicifolia in one or more characters, as the dark 

 polished brown bark of one-year-old branches, rapid glabrescence 

 of leaves, which blacken less when drying and are more coriaceous ; 

 ovaries usually + tomentose, rarely glabrous. 



From roadside half a mile west of Killin, Mid-Perth (No. 99) ; 

 from Glen Shee, E. Perth (No. 680), a form with glabrous ovaries.
