broadly acute: corolla large, the limb bright blue, its lobes broadly 
obovate, the tube about equalling the calyx ; dorsal surface of the 
nutlet slightly hispid or tuberculate, the teeth of the border two 
thirds as long as the body of the nutlet and with bristly points on 
their margins and apex, the bristles at the apex sometimes showing 
a tendency to become glochidiate. 
Type specimen in the United States National Herbarium, col- 
lected July 9, 1901, on Old Man Creek, a tributary of the Koyu- 
kuk River, Alaska, by W. C. Mendenhall. 
£. splendens differs from all other species herein noted in its 
larger flowers, and from other Alaskan species in its larger leaves 
and closely appressed, strigose pubescence, and in the shorter 
teeth of the nutlet. 
Mr. Kearney’s description was from plants in flower only, col- 
lected by G. M. Stoney in the Jade or Baird Mountains. A 
Specimen with both fruits and flowers has since come to hand and 
is now taken as the type for the above description. 
The specimens examined are as follows :

> 4. Eritrichum argenteum sp. nov. 
A low and rather densely villous plant of several short, sterile 
branches forming a tuft or mat 2 or 3 cm. high, this often ex- 
ceeded from 1~5.5 cm. by the flowering branches; the pubescence 
commonly silky and shining or silvery in appearance: leaves on 
the sterile branches closely overlapping, oblanceolate or oblong, 
obtuse or acute, 5-10 mm. long, 1.5—3 mm. broad, those on the 
flowering branches sometimes linear or linear-oblong and usually 
less villous than the lower ones : flower cluster compact when ses- 
sile among the leaves at the end of a branch or raceme-like when 
borne on an elongated branch : calyx lobes linear, densely villous : 
flowers in dried specimens 4-6 mm. in diameter, the limb of the 
Corolla bright blue: nutlets with a dorsal border of triangular 
teeth, these distinctly visible in the young nutlets soon after pol- 
lination and even discernible under a low power of the compound 
Microscope as soon as the flower is fully open ; teeth when mature 
about half the length of the body of the nutlet distinctly connate 
at the base and bearing minute bristles on their margins and apex.

lected J uly 31, 1895, among rocks above timber line, at an eleva-
