Úrtak
Tær báðar størirnar Carex viridula Michaux og Carex
glareosa sum vaksa kring allan norðurknøttin, eru
skrásettar nýggjar í Føroyum. Carex viridula er ein
av vanligastu størunum í Føroyum. Higartil hevur í
Føroyum ikki verið gjørdur munur á Carex demissa
Homemann og Carex viridula. Carex glareosa er
bert funnin á einum staði vestanvert á Suðuroynni við
Hvalba. Lendið har størini vaksa, umframt eyðkennini
hjá størunum, verða lýst.
Abstract
The two circumpolar distributed sedges Carex viridula
Michaux and Carex glareosa Wahlenberg are recorded
as new to the Faroe Islands. Carex viridula is one of the
most common sedges of the Faroes. So far this sedge
is not distinguished from Carex demissa Hornemann
on the Faroes. Carex glareosa could be only recorded
at a location at the westcoast of Suðuroy near Hvalba.
The habitats and the characteristics of the two sedges
are described.
Introduction
Within the scope of a field trip on the Faroe
Islands in July 2001 and 2003, the author
visited the islands Suðuroy, Sandoy, Vágar,
Streymoy, Eysturoy, Borðoy, Kunoy and
Viðoy. On these excursions, the author was
particularly interested in the taxa of Cyper-
aceae. This short note will deal with the oc-
curence of Carex viridula Michaux and the
new fínd of Carex glareosa Wahlenberg in
the Faroes.
Up to now Carex viridula Michaux is not
distinguished from Carex demissa Horne-
mann in the Faroes (cf. Rasmussen, 1952;
Fosaa, 2000; Jóhansen, 2000).
On all visited islands Carex viridula
could be found at suitable locations.
The distribution of Carex viridula is cir-
cumpolar, widespread in temperate areas
up to the arctic zone (cf. Hulten og Fries,
1986). Next to the Faroe Islands Carex
viridula occurs in Iceland (Love, 1983), in
the British Isles (Stace, 1991) and in Scan-
dinavia (Hyllander, 1966).
