ful specimens. However, besides this, I found 6 inew species
and one new variety. Among tlhese there is a fine examplie of a
species belonging to the Alpina Section, íbut ’hitherto no spiecies
of this section has been recorded from Faeroes. This seems to
stress the need for more detailed investigations on the Hieracium-
flora of tlhe isles. The paper contains original descriptions of ithe
new species.
The type specimens are preserved in the collection of the Natural
History Museum in Tórshavn, Faeroies.
Alpina. H. Rasmussenii n. sp. (vide pag. 116), which belongs
to Alpina Genuiina, is a veiy interesting speoies as mo speci-
mens of that Seotion have previously been found in the Faeroes.
Unfortunately it is represented iby one example only. Its further
distribution ds at preeenit not known, and it is not poasible to
evaluate its eventual variability. This new species is distinguished
by its black glands, on the whole stem, by its small eubentire
radical leaves, tlhe sliglhtly developed stem-leaves, the lack of bracts
about the summit of tlhe stem, and iby its darkish and unusual
long-pilose involucre.
Comparing the present .specimen with Icelandic species of this
Seqtion it does noit seem to be closely allied to any of these. As to
the indumentum of the oharaoteristic involucre it resemibles H. ta-
raxacifrons Oskarss. from W.-Iceland, and ithe shape of the radical
leaves is very similar to that of H. percome Om., but in all other
nespeots it differs essentially from t'hese two Icelandic Alpina.
Vulgata. H. saxunense, n. sp. (vide pag. 117) is closely re-
lated to H. subcordifrons Dahlst. ibut it differs from
that species in having slenderer and lower growth,
narrower and longer inner radical leaves and a lower stem-Ieaf.
All the Ieaves are of deeper green colour pilose above, and
without cordate hase. Plhyllaries are narrower, more acuminate
and conspicuously floccose. I have compared many specimens of
H. subcordifrons from different localities with the present speci-
mens. But as I have not bieen abile ito find intermediate atages be-
tween them, I think it justifiable to raise the form mentioned to
a specific rank.
Cørinthoidea. Hieracium haplodontum n. sp. (vide pag. 119).
Tihis species is most closely allied to H. peramplijorme Dahlst.
and H. melanochrotum Dahlst. It differs mainly from them iby hav-
ing broader and characteristic deltoid dentate radical leaves, which
are more pilose above, the large o'bovate shaped lower stemleaf,
