shows in the venation, structure of the margin, and shape of the 

 leaves, its relationship to that species. The specimens are too 

 old to show the colour well, but that of the principal veins is in the 

 direction of 8. reticulata, namely reddish. 



From the look of the examples and the dead wood about them, 

 they seem not to have been in robust condition, and probably 

 the plant grows much larger.

several modifications or so-called varieties of 8. purpurea, they 

 are not altogether agreed as to what these are or as to the names 

 they should bear. 



In Britain the " species " into which Smith and Borrer divided 

 8. purpurea are still retained as varieties of that plant, 

 are Lambertiana, Sm., Woolgariana, Borr., and ramulosa, .d >rr. 

 (sometimes included in Woolgariana) \ and according to Babing- 

 ton, S. Helix, L. 



Audersson has, in addition to the type (a gracilis, Gr. and ttr. 

 -« purpurea, Sm.), Lambertiana, Sm. (including 8. Woolgariana 

 Borr.), and 8. Helix, " L." (which is not the 8. Helix of British 

 hotanists, but seems to be the same as ramulosa, Borr.). 



Wimmer distinguishes the forms eriantha, gracilis, Lam- 

 bertiana, styligera, sericea, and/ 'areata. 



As characterizing their varieties, British botanists lay stress 

 upon the colour of the twigs and upon the form of the stigmas, 

 Points which are almost or quite ignored by the Continental 

 salicologists. That the colour of the bark is not a constant 

 character may be learnt from an examination of almost any 

 living bush, when it will be seen that very frequently the colora- 

 tion depends to a great degree upon exposure to the h„'h . 

 Moreover, from authentically named specimens it would seem 

 that even British botanists do not attach so much importance to 

 this feature as the descriptions would imply. Thus iu Smith s 

 Wbarium Lambertiana (from Lambert himself), whose twigs 

 modern writers describe as purplish, has in two of the flowering- 



spec 



bark.
