more or less membranous and tinged with reddish-violet; petals yellow 
about as large as in À. acer; young fruit with recurvate styles. 
The plant forms tufts with very many long, richly branched roots, 
many old leaf-sheaths and numerous new shoots with leaves with large, 
white-membranous sheats; stems ca. twice as long as the radical leaves, 
stem-leaves inserted on the stem in such a manner that they hardly sur- 
pass the radical leaves.

I agree with the useful and detailed unravelling of the troublesome 
matter concerning À. affimis and related species given by H. G. Simmons 
in his Ellesmere Land Flora (l. c.). Our two specimens are just like his 
material. 
I think that Miss A. Easrwoop has described specimens of R. affinis 
without radical leaves under the new name R. verticillatus, as her descrip- 
tion and figure agree quite well with R. affinis.

I am not quite certain with regard to the naming of this species. It 
as a robust species of the acer-group, which has large, bright-yellow 
flowers, more or less reflexed sepals and flattened, hooked styles (as far 
as can be seen in bloom, no fruits being present in the rich material). 
It agrees well with the description of A. Gray’s variety of À. occidentalis, 
as also with the description given by K.C. Davis, but I think it is not 
merely a form of R. occidentalis, more probably it is a species intermediate 
between the latter and R. acer. Further observations on fruiting material 
must decide the question. 
In the Copenhagen herbarium we have the same form sent from 
HOOKER »ex itinere Franklini< under the name À. Schlechtendalir. 
The species À. Turneri GREENE (Pittonia, vol. 2, 1892, p. 296) from 
Porcupine Prives, Alaska is probably near to the present form, but I have 
not seen any specimens, so that I dare not unite them.
