River and the mouth of Coppermine River by RicHarpson, and which, as 
far as I know, has not been mentioned since. It has red or pink flowers 
and seems to grow in gravelly wet places.

The specimen collected belongs to the more hairy form of this species 
(the so-called A. villosa, var. latifolia LEDEB.) and must be named var. 
arctica R. KNuTH (Primulaceæ, in Das Pflanzenreich, 1905, p. 190).

King Point. In bloom in the later half of June 1906 (17th— 28th). 
I have not had access to the original description of A. Gormanmi 
GREENE in >Pittoniae, but Pax and KnutH quote the description, and the 
rich material collected by Mr. LinDström agrees exactly with it, so that 
I feel convinced that my specimens are what GREENE has named A. Gor- 
mann. The type is from Fort Selkirk, Alaska, and has been collected 
on May 24th, thus in the spring. It is evident that the plants must have 
been in bloom only — and Greene does not describe the fruits —- and 
this is of importance with regard to the conception of the value of the 
species. The only essential point in which A. Gormanni differs from 
A. septentrionalis is that the umbel is densely flowered, i. e. that the 
flower-stalks are short. Now A. Gormanni is only known in bloom, and 
we do not know therefore, if the stalks become longer at fruiting time, 
which they most probably do. But if so, there is no cause to uphold the 
species as distinct from A. septentrionalis. When I nevertheless maintain 
it as a variety, it is because I do not find flowering specimens of A. septen- 
trionalis with such short flower-stalks. At least provisionally the Alaska 
plant may bear the name Å. septentrionalis, var. Gormannit (GREENE), and 
is characterized by the flower-stalks being shorter than or as long as 
the calyx at flowering time, while in the true Å. sepfentrionalis they are 
longer — oftenest much longer — than the calyx.
