Braya purpurascens, (B. Br.) Bunce. 
B. purpurascens, Simmons, FI. Ellesm. [B. alpina, Hart, Bot. Br. 
Pol. Exp.; B. glabella, Meruan, Contr. Greenl.]. 
As already shown by Gexert (Not. Arct. Pl.) the Braya of N. W. 
Greenland is not B. alpina, Sterns. & Hopps, as little as is the Grinnell 
Land plant, which Hart (Bot. Br. Pol. Exp.) also has ranged under the 
same name. I have myself seen the specimens upon which Harr based 
his determination, in the London collections. For my part I did not find 
it, nor has any other collector seen it in Foulke Fjord.

Curiously enough, this plant, although occurring in abundance on 
the rich clay plain at the old Eskimo settlement Etah, has not been 
found, or at least is not mentioned, by any previous collector in these 
regions. Neither do specimens from our area exist in the collections; 
but still there might be a possibility that Harr brought home frag- 
ments of it, which Lance may have seen, for the latter author states 
(l. c., p. 48) that Harr has found A. alpina, L., at Foulke Fjord. Harr 
himself, however, mentions A. alpina only from the well-known local- 
ities at Disco, and Turritis mollis only from Proven (Bot. Br. Pol. Exp., 
p. 24). At all events A. Hookeri is an addition to the flora of N. W. 
Greenland. 
The species, however, does not appear here in its typical form, with 
only one or a few (2—3) erect stems from the rosule. As the Foulke 
Fjord plant differs also in some other respects, [ think it best to describe 
it as a new variety: 
var. multicaulis, n. var. 
Perennis, multiceps, ramis floriferis numerosis (saepe 10 vel plur- 
ibus) decumbentibus, brevibus (10 cm.). Folia numerosa, dense rosulato- 
congesta, pro maxima parte per fructificationem persistentia. Racemi 
densi, pedicelli patuli, 0.5 cm. longi. Siliquae quam in forma typica 
majores, 2—4 cm. longae, leviter curvatae. Semina flavo-brunnescentia.
