two redfruited species, E. Eamesii and E. atropurpureum, which 
are distinct from the South American species but nearer allied to 
them than to E.nigrum. And lately FERNALD has found again 
the redfruited form of E. nıgrum. The several very interesting stages 
in the development of our knowledge of these plants and their 
history are given in the following papers.

From West Greenland redfruited crowberries have never 
been reported, and I have for many years searched for them in 
vain. Berries which do not attain full maturity before the frosts 
set in, will the next spring remain on the shrub in a discoloured, 
reddish-brown state, and have an acid taste. This case is very common. 
Amongst plants dried and sent by Mr. J. Eugenius, 1925, 
was a set of Empetrum nigrum, taken on Narssalik Island, 61°38’, 
on Aug. 23nd, with partially unripe and greenish, partially ripe 
and purplish fruits, but in all other respects a typical E. nigrum. 
Pirola rotundifolia L. var. arenaria Mert. & Kocu. As to the disting- 
uishing characters separating this plant from its nearest allies: 
P. rotundifolia, typical, P. grandiflora and P. americana see LANGE: 
Consp. Fl. Grl. 1880, p. 84; Warmine: Medd. om Grl. 36, p. 60, 
1912; FERNALD»D: Rhodora 1920, p. 121; FernaLp: Ruopora 1904, 
p. 197; H. ANDRES: Österr. Bot. Zeitschr. 1913 (not accessible to 
me, quoted in Hecı: Ill. Fl. v. Mittel Europa vol. V. 3. T., p. 1587). 
According to the last mentioned author, the plant should be scent- 
less, which is doubted by BRAUN-BLANQUET, who treated the 
Pirolaceae in Heats Flora. And, as a matter of fact, on the labels 
of specimens from Newfoundland (Gray Herbarium Nr. 6000) 
expressly stated “fragrant”. 
This plant seems to be very rare in Greenland. From the 
district here treated I have seen a specimen from Ivigtüt (leg. 
Norman) and one from Neria (leg. EUGENIUS). 
— grandiflora Rapius, very rare, at least in the lowland, by us only 
seen S. of Kiagtüt, Tun. F., sterile specimens. It has been taken 
twice, both times flowering, in the same fiord by KornErUP, one 
set from an altitude of 1000 ft.; the other in a bog.
