species of his own, S. Geyeriana, which (with a single exception, 
to be accounted for further on) coincides absolutely with S. macro- 
carpa, Nutt. 
True, Nuttall in his Sylva omitted to mention the habitat of 
his species, and in so far opened the way for misapprehension, 
but on the other hand, the earliest description of S. macrocarpa 
published by Andersson (Sal. Bor.-Amer. p. 19) is ostensibly 
drawn from “ Nutt. in Herb. Hook.” (not from the Sylva at all, 
which, we are led to infer from Dr. Gray’s note, |. ¢. p. 32, was 
at this time unknown to him), and if so, why were Nuttall’s own 
specimens not described, and the recorded habitat given, instead 
of something very different from the other side of the continent! 
t is well known that Prof. Andersson carried forward ‘his 
elaboration of the genus Salix under exceptionally favorable cir- 
cumstances. The richest collections were placed in his hands, 
and every possible facility accorded him by the most eminent 
hotanists of Europe and Ametica. It is therefore altogether rea- 
sonable and fitting that those of more limited opportunities should 
accept without questioning, as I myself have done, opinions ap- 
parently reached after a careful survey of the most reliable sources 
of information. Such being our confidence in this distinguished 
monographer, it is all the more to be regretted that he did not in 
the present instance show a fairer appreciation of the work of 
Mr, Nuttall, and a more impartial criticism of his own, whereby 
the astonishing coincidence between S. Geyeriana and the older 
8. macrocarpa could scarcely have escaped his attention. The 
single exception, to which allusion has already been made, con- 
sists in what is said of the male aments of Geyeriana being “ses”

explain in a quite unexpected and satisfactory way. ey~
