Petrop. 5:107. 1877), of which he remarks: ‘Solum modo ovariis 
et bracteis parce puberulis a var. typica recedit. Forsan S. arcticae 
proles hybrida.” Without having seen TRAUTVETTER’S type, 
which had been collected by CzEKANOWSKI and MUELLER “‘inter 
fl. Olenek et fl. Lena inferiorem, ad fl. Tyria in tundra,” I am not 
sure whether the following plants really represent TRAUTVETTER’S 
variety: Unalaska, Kiuliuk, September 30, 1871, M. W. Harrington 
(fr.; G.), Dutch Harbor, July 17, 1899, B. E. Fernow (f., fr.; Cor.), 
Kodiak Island, July 2-4, 1899, B. E. Fernow (f., m.; Cor.), and 
Yakutat Bay, Disenchantment Bay, August 13, 1892, F. Funston 
(no. 117 partim, fr.; Cor., M., N.). LepEBour (FI. Ross. 3:6109. 
1849-51) has described a variety with entirely glabrous fruits under 
the name var. lejocarpa, the type having been collected by ERMAN 
in Kamchatka, in ‘‘ignivomo Schiwelutsch” (Shivelutch). This 
specimen, which I have not yet been able to compare, was men- 
tioned by CHamisso (Linnaea 6:541. 1840) as a form of S. arctica 
Pall., while ANDERSSON (1868) referred it to his S. Pallasii var. 
diplodictya. The true S. diplodictya Trautv. came from the 
“insula St. Laurent,’ and its main difference from typical S. 
arctica is, according to the author’s description and figure, the 
“folia . subtus pallidiora nec glauca nec  glaucescentia, 
utrinque lucida.’’ I have seen no specimen with such leaves, but 
CovILLe states that “occasionally specimens are found which lack 
the glaucousness of the lower leaf surface, a character on which 
TRAUTVETTER based chiefly his separation of diplodictya.” Ryp- 
BERG, who kept diplodictya as a species, interpreted it in a very 
different way, and referred to it certain forms of which I shall 
speak under S. ovalifolia. 
The var. subcordata previously mentioned from southern British 
Columbia is a form that needs further investigation. It has been 
described by AnpERsson in Ofvers. K. Vet.-Acad. Férh. 15:128 
(Bidr. Kanned. Nordam. Pilart.). 1858; in Proc. Amer. Acad. 4:69 
(Sal. Bor.-Am. 24). 1858; in Walp., Ann. Bot. 5:754. 1858, from 
specimens collected by Drummonnp in the “ Rocky Mountains.” In 
1890 Bess (Bor. Gaz. 15:55) dealt with this rather obscure plant 
and stated that “the specimens from which the description of this 
Supposed new species was drawn are all attached to a single sheet
