O b s .— Since Hooker’s time there has been considerable doubt
as to whether this form should rank as a species or not. In his
“ Bnt. Jung.” it IS published as a variety of S. nemorosa, but from
this It IS distinguished by tlie shape of its leaves, which are also
only denticulate, not ciliate, in many respects approaching
N. undulata. Dr. Gottsche, writing to Dr. Carrington many
years ago, said; “ I cannot yet define the limits of these species
[S. nemorosa and A. undulata), and if I believe myself for a time in
order with the genus, new forms confuse me again.”
I t appears to occupy the same position between A. middata and
A. nmmrosa as A. intermedia, Husn., does between S. purpurasoens
and 8. zmh'osa.
