SUMMARY.
THE ROSE ROOT, SEDUM ROSEA (L.) SCOP. IN ICELAND.
The Rose Root, Sedum rosea (L.) Scop., is a common plant in Iceland, growing
in three kinds of widely different habitats, e. g. the walls and roofs of tlie old
Icelandic turf-houses, in rock crevices and ledges, and on sandy and gravelly flats
in the mountains, then being of nanous growth. It has a great amplitude of vertical
distribution, ranging from bird cliffs at the seashore to mountain tops of 1000 m
or more.
Yet in the inland valleys it has a distinct lower limit of growth, mostly at about
500 m.
The Rose Root is an old medical plant in Iceland, as indicated by the numerous
popular names of this plant. According to an old custom it should prevent fire,
this truly being the reason why it is to be found on the turf-houses.
