[3][5][6] Gentianella amarella the autumn gentian, autumn dwarf gentian,[3] or autumn felwort is a biennial herbaceous plant, which only produces a low leaf rosette with elliptical to lanceolate leaves in its first year.

The stem is straight or branched just above the base; at flowering time it is without leaves which distinguishes it from similar species.

The relatively small, hermaphrodite flowers are purplish bells (reddish-violet corolla) are trumpet-shaped between 12 and 22 mm long and have five petals with double perianth (calyx and corolla).

The new combination to Gentianella amarella was published in 1912 by Carl Julius Bernhard Börner.

[7] There are about five subspecies of Gentianella amarella:[citation needed] Its habitat is in grass, often on lime-rich soil (in England typically on chalk).
