THE BRITISH WILLOWS 



S. phylicifolia replacing those of S. Andersoniana. The one-year 

 old wood polished dark brown in part at least ; twigs sooner 

 glabrescent. Stipules narrower, less prominent and less cut. 

 Leaf-blades rather rigid and coriaceous, brighter green, not 

 blackening at all, sooner glabrous, pale green or glaucous beneath. 

 Catkins with bracts lingulate or oblong-obovate, obtuse or sub- 

 acute, somewhat ferruginous; ovaries always pubescent, often 

 densely. 



Local, if not rare, occurring in subalpine valleys and among 

 mountain rocks, from N. W. Yorks and Dumfriesshire to Perth- 

 shire and Forfarshire, Aberdeenshire, Caithness. No European 

 specimens met with.

A low spreading shrub, 1-3 ft. high ; stems ascending, more 

 rarely suberect, twigs and buds pubescent at first, soon glabrous. 

 Stipules small or of medium size, | -ovate to ovate-acuminate. 

 Leaf-blades 1-2 in. long, usually oblong-obovate or oblong-oval, 

 sometimes obovate-lanceolate (var. spathulata Willd.), or shortly 

 lanceolate (var. undulata Syme) ; or with larger and more silky 

 leaves (var. major Syme) ; + narrowed towards the base, with 

 tip acute, often recurved or twisted ; serrate, crenate-serrate, or 

 subentire, + rugose (nerves depressed above and raised beneath) ; 

 dark green and glabrescent, sometimes grey-pubescent, at least at 

 first above, glaucous and silkily pubescent or subglabrous beneath. 

 Catkins preceding the leaves, in late April or May, shortly stalked 

 with few small silky leaves at the base; filaments somewhat 

 pubescent near the base ; $ about 1 in. long, dense-flowered, 

 elongate in fruit; pedicels 3-5 times as long as the short quadrate 

 nectaries ; bracts oblong to obovate obtuse, pilose upwards ; 

 ovaries narrowly conic, silvery-grey with appressed pubescence ; 

 stigmas short, thick, subsessile. 



Four varieties have had a place in British lists, and are 

 described by Syme (I. c.) ; but these do not include every form, 

 and many examples cannot be fitted into them. It is doubtful 

 whether any varieties of this variable hybrid are worth retaining 

 in the list. 



'S'. aurita x repens is very local, but widely spread, at low 

 levels, from the Orkneys and Shetlands to Cornwall, Sussex, and
