near to it; another distinctive character is that the leaves are glabrous 
on the upper surface and more adpressed-hairy below. It agrees well 
with the description given by P. A. Rydberg (l. c.) of S. Seemanii nov. Sp. 
from Dawson, Alaska. Coville takes this as an unimportant form of S. 
glauca, but I think it may be of some systematic value, if not a separate 
species as proposed by Rydberg.

l. c, p. 47. — T. purpurascens Rydberg, Bull. Torr. Botan. Club., 28, 1901, 
p. 281. (See pl. III, fig. 17.) — Arctic North America: King Point. 
Flowering specimens in the last week of June 1906 (20. —28.) — Herschell 
Isl. Flowering on July 18. 1906, and with yearold pods. — The North 
American forms of the polymorphous T. alpestre differ in some respects 
from the European one and should perhaps bear special names, as P. A. 
Rydberg (l. c.) has suggested; but at present it seems to me better to 
treat them as varieties until further researches have decided the question 
on the specifie range. — Our specimens agree in the main with Ryd- 
bergs T. purpurascens described from Arizona and Colorado.
