allies only certain shortened and merely leafy-bracted twigs 
bear flowers, the larger branches with true leaves over- 
shadowing these, and bearing no flowers at all. 
PnrMULA ExiMIA. Rootstock simple; scape6 to 16 inches 
high, twice or thrice exceeding the foliage: spatulate-oblong 
or oblanceolate leaves thin, glabrous, entire or obscurely 
crenate or dentate: upper portion of the scape, and more 
particularly the pedicels, densely white-farinose: umbel few- 
flowered and somewhat one-sided, the flowers inclining one 
way: calyx cleft to the middle or a little more, the segments 
oblong-linear, scarcely acute: corolla very large. rich dark 
purple, its segments entire orsomewhat erose, not emarginate. 
St. Paul Island, Behring Sea, Mr. Macoun, 1896 and 1897; 
also by several early collectors, and usually referred to P. 
nivalis, for what reasons it would not be easy to say. 
Primura Macouxir Stouter than the last, the rootstock 
branched and the scapes and leaf-clusters thus tufted, form- 
ing a mass: leaves obovate to oblanceolate, entire, glabrous, 
the inflorescence slightly glandular but without trace of 
farinose indument: umbels many-flowered and perfectly 
equilateral: calyx cleft well below the middle, its broad 
segments oval, or if narrower somewhat spatulate-oblong : 
corolla much as in the preceding, but of a lighter purple. 
Abundant on St. George’s Island, and doubtless elsewhere 
on shores of Behring Sea; my specimens obtained by Mr. 
Macoun in 1897. Itis more uearly related to P. Parryi than 
to P. nivalis, an inland Asiatic species to which, by guess, it 
has been referred. 
PRIMULA mucronata. Near P. Parryi, rather smaller, 
more copiously leafy, all the leaves narrower, entire, obtuse, 
tipped by a very abrupt soft herbaceous mucro 1 to 1 line 
long; calyx more deeply cleft, the segments relatively nar-
