Stray Contributions to the Flora of Greenland I—V. Q 
Dryopteris Phegopteris (L.) C. Cur., common. 
— Linnaeana C. Cur., common. 
Polystichum Lonchitis (L.) Rorx, common. 
Athyrium sp. An immature set of specimens was found at Kangkitsog. 
An indusium is present, which would bring the plant to A. Filix 
femina (L.) Roru, heretofore not observed in Greenland; but the 
fronds are so young and undeveloped that a definite identification 
is impossible. 
From 6 localities on the southern part of the east coast, be- 
tween 60° and 61° N., has been found an Athyrium which has 
passed as A. alpestre (Hoppe) RyLanps. It was also found once 
in the Ilua Fiords of the west coast. In 1917, Fr. K. Burrers has 
shown (Rhodora 1917, p. 203) that the American material forms 
a very distinct variety americanum Burt. Having applied to Dr. 
C. CHRISTENSEN, he kindly revised the material and wrote: 
In the Copenhagen herbarium there are only 5 sheets of A. alpestre from 
Greenland. Most of them are not well developed and difficult to identify de- 
finitely, but at least the specimens from Kuteq, 60°41’ N. (Egerrın), and Nenese, 
| 60°18’ N., (J. VAHL), are undoubtedly v. americanum as described by BuTTers. 
The Icelandic specimens all belong to the European typical form, only 
one frond from Husavik (East-Iceland leg. H. Jonsson) approaches much 
to v. americanum. 
Our specimens from America, especially specimens from Québec, show 
that the variety is very well characterized by Burrers. 
(in litt.). 
Asplenium viride Hups., not seen. 
Botrychium Lunaria (L.) Sw., common. A monstrous form with sporangia 
on upper parts of the sterile fronds was noticed at Qagssiarssuk, 
Ig. F. 
— boreale MILDE, Prins Christians Sund; Taserssuaq, Tas. F.; Igd- 
lorsuit, Il. F. | 
— lanceolatum (GMEL.) AANGSTR., seems to be rare in this section. 
| By us only found S. of Kiagtät. 
Equisetum arvense L., common. 
— silvaticum L. seems to be quite rare in this section. From Tasers- 
suaq, Tas. F. it has been taken by all previous collectors. We also 
took it here where it was very abundant, and from two other places 
in the same fiord. From Tunugdliarfik F. it has once been collected, 
(ROSENVINGE), and we found it here S. of Kiagtüt. Finally it was 
found at Eqaluit, Ig. F.
