Apart from a few species, which are planted as ornementals, two species of the genus Sanguisorba grow naturally in Iceland, namely Sanguisorba officinalis L. and Sanguisorba alpina Bunge. However, up to the present all references in the literature and herbarium collec- tions have only recognised S. officinalis, al- though specimens of both species are present. This paper aims to describe the characteristics which differentiate between ihem and describe their respective distribution in Iceland. S. officinalis is an old member of the Icelandic flora, probably colonising the country soon after the end of the last glaciation. It is found as two seperate populations in southwest and west Ice- land and does always occur in undisturbed plant communities. On the other hand, S. alpina is an introduced alien which became naturalised dur- ing the late 19th or, at the latest, in the early 20th century. It grows in and around abandoned gar- dens or on disturbed sites in various parts of the country. The occurrence of S. alpina as an alien is peculiar to Iceland as it has never been re- ported from other parts of Europe, where it is rarely cultivated except in botanical gardens. ■ HEIMILDIFL Cullen, J. 1995.
