Sideritis (also known as ironwort, mountain tea and shepherd's tea) is a genus of flowering plants well known to man for their medicinal properties.

The genus is composed of short (8-50 cm), xerophytic subshrubs or herbs, annual or perennial, that grow at high altitudes (usually over 1000 m) with little or no soil, often on the surface of rocks.[1][2][3][4]

It is pubescent, either villous or coated by a fine, woolly layer of microscopic intertwined hairs.

Sideritis inflorescence is verticillaster.[2][5]
