Found in many places in the southem part, in one locality in S.E. (Laxárdalur
in Hornafjörður (I.Ó., 1937a, p. 42), and in one locality in N.W. : Laugaból at
Isafjörður (cp. Fletcher, 1938, p. 392). See fig. 164. Sometimes cultivated as an
ornamental plant in gardens, e.g. in Akureyri, N., and in Reykjavík, S.W.
The variety excelsa (Poir) — V. sambucifolia Mikan, has long stolons and fewer
(5—11) leaf-segments, the terminal one much longer and broader; some of the
specimens in H.H. seem to correspond fairly well with this variety, but the material
is on the whole too scarce for a sure determination.

On herb-slopes and rocks; in copses, damp places, ditches.
