Sideritis Glacialis

This very rare plant makes a low spreading clump of small, hairy, grey-green leaves on short stems, holding stubby heads of pretty, pale lemon flowers. Although most sideritis species grow at low altitude, the group of high altitude taxa are endemics, usually with a small distribution areas. In this species it is incompletely-known, and it is threatened with extinction, living at the very upper altitude limit of this section, some 10,000 feet up in the Spanish Sierra Nevada.
