Bordö: Klaksvig (A. Poulsen, 1886); Str.: Kirkebö. Thorshavn and 
Sandegærde (C. A Feilberg & E. Rostrup, 1867); Syd.: Tværaa and Trangis- 
vaag, rock-ledges at Kvanhaugen (J. Hartz, C. H. Ostenfeld & E. Warming, 
1897); Viderö: Malinsfjæld, 300 M. (J. Hartz & C. H. Ostenfeld, 1897). 
Mr. Dahlstedt remarks: »The characters given above are only re- 
lative, and they are such as might possibly be induced by the place 
of growth, but that is not the case. I have had specimens raised 
from fruits from Syderö under cultivation through several genera- 
tions, and they keep themselves distinct from cultivated specimens 
of the main form (from Sverige, Jemtland)«. 
var. maculiferum Dahlst., nov. var. 
A forma primaria et a var. precedente satis diversum foliis in 
pagina superiore + purpureo-maculatis squamisque paullo laxius 
adpressis. 
Syd.: Tværaa and rock-ledges at Kvanhauge (J. Hartz & C. H. Osten- 
feld, 1897); Str.: Havnedal near Thorshavn (C. H. Ostenfeld, 1903). Col- 
lected in the Færôes as early as 1821 (by Trevelyan?), as there are 
specimens in the Riksmuseum of Stockholm, labelled: »Faeröe, 1821, about 
2000 feet above the Sea.« [Also collected on St. Kilda, Outer Hebrides by 
O. Paulsen, 1905). 
»This variety differs only from the foregoing form by the cha- 
racters given in the diagnosis, but as it seems that both characters 
always are combined, it is probable, that they are persistent. — 
The variety in question is of special interest, as it in many re- 
spects reminds us of the nearly related species T. naevosum Dahlst.«
