DR. F. BUCHANAN WHITE S 









In Britain, judging from the specimens I have seen, Salix tn- 

 andra exhibits fewer extreme forms of variation (though variable 

 enough both in leaves and catkins) than it does in continental 

 Europe. The 4 London Catalogue ' var. a. amygdalina seems to 

 be equivalent to Andersson's a. discolor, which he says is S. amyg- 

 dalina, auctorum {S. amygdalina, L., if not altogether dubious, is 









latifoli 



Hoffmanniana is /3 





andra and 8. viminalis, and will be considered hereafter. Speci- 

 mens named by Leefe S. contorta, Crowe, do not altogether agree 

 with Smith's description of that plant, which he says has leaves 

 half the size of those of S. triandra. Leefe's contorta has long 

 leaves, which in several ways suggest a cross of triandra with 

 fragilis ; but the catkins (?) are in all essential particulars those 

 of triandra, of which species it seems to be only a leaf-form. 



Andersson is of opinion that his discolor is in Western Europe 

 a more truly wild form than concolor, which is the more fre- 

 quently cultivated one. In Britain concolor seems to be the 

 commoner, and is more usually broad-leafed than narrow-leafed. 

 In Linne's herbarium there are not any specimens named 

 S. triandra ; but a plant labelled by Linne " hastata " (and by 

 Smith " triandra ? ") appears to be S. triandra, with leaves glau- 

 cous below ; and another example, labelled by Linne " Salix 

 pentandra " (to which Smith has put a " ? "), and with, in another 

 hand, a stuck-down label with " Salix pentandra, Flor. Lap. 370. 

 Foliis subtus cinereis. No. 8," seems also most probably S. tri- 

 andra, with leaves narrowed at each end and glaucous below.

x Salix decipiens, Hoffm. (S. triandra X S. fragilis.) 



In his ' Historia Salicum" (vol. ii. fasc. i. p. 9, t. 31, 1791), 

 Hoffmann describes and figures a willow, which he named 

 S. decipiens, from the resemblance of the leaves to those of 

 S. higemmis ( = $. daphnoides), and which, he says, is one ot 

 several species that go by the name of S. fragilis. Smith, 

 amplifying the description, adopted Hoffmann's species, and was 

 follow ed for a considerable time by British botanists. The more 

 recent British authors have, however, placed S. decipiens as a 

 variety of S.fragilis, and have omitted more or less to notice 

 important points of its characteristics. 



The continental salicologists, on the other hand, very soon 

 began to consider S. decipiens as either a synonym (e. y.Willdenow, 

 as also Lindley amongst British botanists) or as a mere variety
