 an tantuni pro parte?. — As I have already pointed out, I have not been 

 able to compare the specimens which ought to be regarded as the types of 

 Ande^rsson's var. cordata (see, however, my footnote on p. 194), var. acqualis 



and his subspecies or variety pseudocordaia. In 1909, Ball used the name 

 pseiidomyrsinites ** Andersson" for the forms I am inclined to refer to the 

 present species. Andersson did not publish such a species but only a 

 subspecies which he later (18G7) reduced to a variety. As explained above 

 Andersson's first subspecies S. pseudomyrsinites (1858) is nothing l)ut a 

 form of S, viyrtillijolia (var. lingidata (And.) Ball). Strictly s})caking 

 Andersson 's subspecies S. pseudocordafa (1867) is the same as his sub- 

 species S. curtiflora (1858) which, as already stated, must be regarded as 

 a synonym of S, inyrtillifolia, Rydberg did not publish the name S. 

 pseudocordafa with a new description; he only said: *'13. Salix pseudo- 

 cordafa Andersson (S. Novae- Angliae pseudocordafa Andersson)." There- 

 fore, in my opinion, the name S. pseudocordaia Rydberg can hardly stand. 

 I think tliat the so called S. pseudomyrsinites and pseudocordafa or curtiflora 

 of Rydberg and Ball should receive a new name. Ball in 1909 had a 

 *S. pseudomyrsinites var. equalis (having in mind Andersson's var. acqualis 

 cited above) and referred it in his MS.-list to pseudocordafa, of wliich he 

 also i)roi)oses a var. cordata which in his opinion is the same as Andersson's 

 var. cordata mentioned above. Not having soon Andersson's types I do 

 not know whether Ball is right in regarding them as identical with the 

 forjus mentioned below. Without a careful study of the type specimens 

 it seems to me impossible to understand tlie real meaning of Andersson's 

 descrii)tious. I sincerely liope that Mr. Ball's investigations will throw 

 much light on these obscure forms. He certainly will give us a good 

 dcscri])tion of this species and its variabiHty. 



The following specimens I am inclined to refer to it, partly on the 



authority of Ball himself. See also the details given in the keys. The 

 forms with pilose pedicels need special observation, and they sometimes 

 remind one of S. vionticola, having, however, concolor leaves. There may 

 be hybrids among them.
