this note regarding it (Watson in ' Botanical Gazette,' No. i->, 

 1851) :— " Specimina foliifera ad S. viridem, Fr— nmentifera ad 



aqilem, L., pertinent," * I have not seen the specimens in

Watson's herbarium, but there seems no reason to suppose 

 they are different from other examples sent out under the same 

 name and number by Leefe at the same, time, and similar also to 

 specimens published in his second fasciculus. These specimens 

 are, beyond doubt, the Salix fragilis of Smith, and have an almost 

 sessile, ovate-conic, obtuse, short-styled ovary. Andersson had

case with Leefe's specimens, shows characters in direct opposition 

 to his diagnosis of fragilis, but quite in accordance with the de- 

 scription of viridis. What adds to the unintelligibility of Anders- 

 son's note on Leefe's specimens is that the leaves of the latter do 

 not belong to the most intermediate condition of viridis, but are

good 



knowledge of viridis on Andersson's part. An explanation oi 

 the mystery may be this, that, in the first place, there was time 

 only for a hurried examination of these and the Kew specimens, 

 and, in the second, a belief, adopted from others, and not verified 



the same as the continental plant.

 three forms— a. viridis (with leaves green below), b. glabra (leaves 

 glaucous below), both being glabrous t ; and c. vestita, which is 

 the same as Andersson's albescens. 



Nyman (' Conspectus ') thinks that three varieties are of major 

 value, viz. 8. Busselliana, Sin., S. excelsior, Host, and S. P a ~ 

 lustris, Host. Busselliana, Sm., is, as has been shown, not rightly

 not mention Nos. 51 and 52.

 glabra are pubescent, but seem to become glabrous bv SDriner.
