As corroborating the belief that our decipiens is not known, 

 under that name, to Continental botanists, it may be mentioned 

 that specimens quite the same as it were collected at Konigsberg,

Like all hybrid forms (and indeed all willows) its characters 

 are more or less unstable ; but usually it is so well marked that 

 it is not difficult to recognize, though some leaf-specimens may 

 be confounded with S. fragilis and others with S. triandra. I n 

 fact examples of what seems certainly to be decipiens were 

 sometimes named triandra by the older botanists, as Forster, 

 Borrer, &c. ; and I have seen bushes and specimens which, so far

whereas fragilis attains the stature of a big tree, decipiens does 

 not grow to more than a large bush or small tree — I refer, of 

 course, to plants which have never c been cut over. The bark of 

 the trunk and older branches seems rougher and more broken 

 than m fragilis, and, though not deciduous, as in triandra, appears 

 inclined to split up. The branches are more upright in their 

 direction than in fragilis (i. e. they form a more acute angle with 

 the stem), and while somewhat brittle at their points of insertion, 

 are less so than in fragilis. The year-old twigs are, as described 

 by Smith, &c, highly polished, shining " like porcelain, as if var- 

 nished " (had Baenitz this description' in view when he named 

 his specimens vwcporcellanea ?), and most usually of a yellowish- 

 lay-colour. The polish of the twigs has always been
