THE BRITISH WILLOWS 53 



very nearly to the description above, but has the ovaries densely 

 pubescent in the upper half and glabrous below the middle, the 

 pedicels pubescent near the base and glabrous above, and the 

 nectaries rather long oblong, and is probably S. caprea x Ander- 

 soniana-phylicifolia rather than the simple hybrid S. caprea x 

 phylicifolia. 



S. caprea x phylicifolia is an extremely rare combination in 

 Britain, and apparently elsewhere. It has been much confused 

 for many years past with S. laurina Sm., which is the corre- 

 sponding hybrid of S. cinerea with S. phylicifolia, and of more 

 frequent occurrence. Andersson interpreted S. laurina as S. 

 caprea x phylicifolia (DC. Prodr. xvi. (2), 250), and his views 

 were adopted by F. B. White (Revision, p. 403), and rather 

 commonly taken for granted in this country. For an account of 

 S. laurina Sm. see S. cinerea x phylicifolia, p. 57.

A dwarf shrub, with the habit of S. repens in British forms ; 

 twigs pubescent, sooner or later glabrescent. Stipules roundish, 

 blunt or acuminate. Leaf-blades 1-2 in. long, rather broadly oval 

 rounded below with a short tip often twisted, crenate-serrate or 

 subentire, softly and densely pubescent especially beneath while 

 young, gradually and slowly glabrescent. Catkins slightly pre- 

 ceding the leaves in April, shortly peduncled with 2-3 small basal 

 leaves, $ 1 in. long cylindric, bracts subobtuse ; ? catkins (from 

 Hamburg and E. Prussia) \-\\ in. long, bracts oblong acuminate 

 (Tilsit) or oblong-obovate (Hamburg) ; ovaries gradually acuminate 

 to a short style, grey-tomentose; styles and stigmas nearly equal.
