style. The leaves, so far as I can see, always possess stomata in 
the upper epidermis, as is the case with typical S. stolonifera, while 
they are wanting in the leaves of typical S. arctica and S. ovaltfolia. 
The length of the style and the rather long linear stigmas seem to be 
the best characters to distinguish S. stolonifera from the other 
species of this group. “The characteristic of the production of 
slender leafless, subterranean branches or stolons’ is not always 
clearly seen on herbarium specimens, and the presence of such 
stolons may possibly be detected in other related species.

locality of the species is Cape Espenberg in the Kotzebue Sound. 
Its range extends from the Bering Strait, where it is probably also 
found on the Siberian Coast,’ northward to Point Barrow and 
Martin Point, where it has been found by F. Johansen, July 30, 
1914 (no. 136” or 93484 O., fr.); and southward to the Pribilof and 
Aleutian Islands and the Alaskan Peninsula, but it has also been 
collected on Kodiak Island, and to the eastward as far as Yakutat 
Bay. The typical form has glabrous ovaries and fruits; there are, 
however, specimens with loosely pubescent capsules collected by 
Trelease and Saunders, St. Paul Island (no. 3442, fr.; M.), which 
may represent the var. pubescens And. (DC. Prodr. 167: 291. 1868). 
This is described as being distinguished by “‘capsulis tenuiter hir- 
sutis griseo-pubescentibus petiolis et foliis basi longius hirsutis.” 
As no type is given, I cannot decide whether ANDERSSON’S variety 
is identical with this specimen. 
Some other specimens which Covitte has cited as typical S. 
arctica, while RYDBERG took them for S. diplodictya Trautv., should 
be discussed. The last species has been described, as I have 
explained, as having the leaves green and glossy on both sides, and 
7Lg. C. Wricut in 1853-56 on Arakam Island. Those specimens are distributed 
as S. uva-ursi, but agree well with S. ovalifolia except that the fruits are not glaucous.
