432 DR. F. BUCHANAN WHITE' S 



a specimen (without date and without flowers) labelled S. Arbus- 

 cula. Of recent years it has been found in several places in 

 Breadalbane, with both <$ and $ catkins, by Messrs. Meldrum, 

 Haggart, and Brebner, and by myself. 















Group 9. NiTiDULiE. 



14. Salix Myrsiketes, L. 

 Considering how, on the whole, well-marked this species is 



great 



Andersson 



says that the ovary is sessile, with the nectary passing its base ; 



"Wimmer (with whom Grenier agrees) 



W 



is sessile (in 8. procumbens nearly sessile) ; Walker- Arnott (for 

 both " species ") that the pedicel is usually as long as or at 

 length longer than the nectary ; Boswell-Syme that the pedicel is 

 about as long as the nectary ; Babington that the ovary is sub- 

 sessile ; and J. D. Hooker that it is distinctly pedicelled. 



Then as regards the shape of the ovary, Andersson describes 



) 



it as ovate-conic rostrate (in /3. Jacquiniana, thic 

 scarcely pedicellate) ; Wimmer, conic-oblong, alv 



a, more slender and often somewhat acute in /3. --^ 



Koch, lanceolate-acuminate from an ovate base, at first sessile and 

 hairy, at length very shortly pedicellate and glabrous ; Grenier, 

 ovoid shortly conic ; W. J. Hooker and Walker-Arnott, lan- 

 ceolate ; Boswell-Syme, lanceolate-conical or conical-subulate; 

 Babington, ovate-subulate. 



(By Andersson the <3 catkins are described as yellowish, the 

 anthers at length becoming blackish ; but "Wimmer more correctly 



says that the filaments are purplish, and the anthers purple- 

 violet.) 



From the descriptions of the ovary, it would appear 







i 



that 



British botanists attribute a longer pedicel to the species than 

 the Continental botanists do, and that on the whole they are 

 inclined to describe the shape of the ovary as lanceolate. 



The result of the examination of a number of specimens shows 

 that there is a considerable range of variation in the length of 

 the pedicel and shape of the ovary, without, however, any notably 

 extreme forms. The Central-European plant seems usually to 

 have a shorter capsule and pedicel than the North-European. 

 Scottish examples are more (though not altogether) in accord-
