ROSA BLANDA Ait. 
According to Watson, &. dlanda extends from Newfoundland 
to Hudson’s Bay, and southward to northern New York, whence 
it extends to the west as far as Minnesota, traversing Ontario, 
Michigan, Illinois, and Wisconsin, and appearing again to the 
north in Manitoba. We have in this a boreo-oriental dis- 
tribution. In the consideration of R. Arkansana a little later we 
shall see whether this western limit of R. d/anda should not be 
extended. Recently, Mr. Holzinger (oc. cit.) has pointed out 
R. blanda as occurring in Idaho (valley of Little Potlatch 
river, no. 381; Lake Coeur d’Alene, no. 581), but no. 581 of 
the Sandberg collection, of which I have received a beautiful 
specimen, appears to me to belong well to R. Nutkana. Its prickles 
are paired, its leaflets are pubescent and with simple teeth, its 
pedicels are ordinarily hispid-glandular, and its sepals are glan- 
dular without. As for no. 381 of the same collection, there is 
not the least doubt that it is R. Nutkana, with pubescent leaflets 
and simple teeth, and pedicels, receptacles and sepals smooth. 
The corolla is very large, 
R. blanda, which often has pubescent leaves, sometimes displays 
leaves perfectly glabrous; the teeth are almost always simple, 
and very rarely do they become glandular-compound. Rarely, 
also, are the leaves a little glandular beneath, and the receptacles 
hispid-glandular. Different ages may give rise to various series 
of variations. 
Rosa ARKANSANA Porter. 
In my Nouvelles remarques sur les roses américaines (1889) I 
have discussed at length the value of R. Arkansana, which I had 
concluded to consider only a variety of R. dblanda. 
According to the terms of the original description, the name 
R. Arkansana can strictly apply only to the form producing simple 
stems crowned with a terminal inflorescence. These simple stems, 
about a foot high, are more or less clothed with scattered, slen- 
der, straight and often setaceous prickles; the leaves, which are 
really cauline leaves, have four or five pairs of leaflets; and the
