LONDESIA, A DISTINCT GENUS FROM BASSIA (CHENOPODIACEAE)

Londesia eriantha has sometimes been included in Bassia eriophora as a synonymy or as a variety of it. It has sometimes been known as a distinct species but under the genus Bassia. Both species occur in Iran and they are morphologically distinct and geographically separated. Londesia eriantha has no appendages on perianth segments and it distributes from C. Asia to the centre of Iran. Bassia eriophora bears rather long spines on perianth segments and it has a distribution from N. Africa eastwards through Palaestine and Arabia to S. of Iran. As appendages of Perianth in this group and also the whole Chenopodiaceae family is a generic diagnostic character, the two species are kept in different genera, i. e. Londesia and Bassia.
