THE BRITISH WILLOWS 63 



localities given ("at Wrongay fen, Norfolk," and "near Shobden 

 Court, Herefordshire," Engl. Fl. p. 173) are from counties which 

 are not known to have produced any form of the species in 

 question. 



In his Observandum, at the beginning of his Salices Scand. 

 fasc. iii., S. J. Enander has demonstrated that the name S. nigri- 

 cans Sm. belongs only to the $ plant, of which one sheet is 

 preserved in Smith's herbarium (Enander, I. c, No. lOlf) ; and 

 argues that as Fries first detected the false basis on which Smith's 

 S. nigricans 2 rested, and worked out and described the true $ 

 plant, the name should rightly be S. nigricans $ Smith atque $ 

 Fries ex pte. 



Another solution of the difficulty seems preferable to this 

 complicated nomenclature. In Smith's herbarium the typical $ 

 of this species is well represented by specimens of S. Andersoniana 

 Sm. ; and if the name S. nigricans Sm. be rightly discarded (as 

 nomen confusum), the name S. Andersoniana Sm. (E. Bot. t. 2343 ; 

 Engl. Fl. iv. 223) is well qualified, by drawings, description, and 

 specimens, to take its place. 



Of the forms which, formerly described as species, have been 

 placed as varieties under S. nigricans by Syme, Babington, and 

 others, var. Damascena (Forbes) with broadly ovate leaf-blades 

 green on both sides, var. petroea (G. Anders.) with narrow oblong or 

 oblong-lanceolate leaf-blades, and var. hirta (Sm.) with the blades 

 oval-oblong, are synonymous with S. Andersoniana. Vars. cotini- 

 folia(Sm.),Forsteriana (Sm.), &n&rup>estris (Sm.), having pubescent 

 ovaries and rather rigid leaf-blades which are not uniformly blackened 

 when dried, are transferred to S. nigricans x phylicifolia. Var. 

 tenuifolia (Sm.) is in the main another hybrid ; Borrer detected 

 the identity of the Kirby Lonsdale plant, on which it was partly 

 founded, with S. laurina Sm., i. e. S. cinerea x phylicifolia (see 

 Journ. Bot. Suppl. 1904, p. 187) ; and a specimen of this Kirby 

 Lonsdale plant in hb. Smith confirms the identification. 



S. Andersoniana Sm., hitherto known commonly as S. nigricans 

 Sm., usually a subalpine shrub but descending to near sea-level 

 in the North of Scotland, is widely distributed from the Orkneys 

 southwards to Lancashire and Yorkshire, and also occurs in 

 Warwickshire. Smith's records from Herefordshire and Norfolk 

 have not been confirmed. It ascends to 2500 ft. in the Highlands, 

 where it is not unfrequent as a dwarf trailing under-shrub on 

 moist mountain rocks. Recorded from Donegal, Antrim, and 

 Londonderry, but not seen for many years; Westmeath (planted). 

 Mountain regions of Central and Southern Europe, Scandinavia, 

 Russia ; Syria, W. Siberia, and Kamschatka, in Asia.
