Polygala amarella

Perennial herb.

5–15 cm high.

The plant is multiple-stemmed. The stems are ascending, simple or few-branched, angular, non-lignified and pubescent.

The leaves are elliptic – elongate, simple and pubescent. At flowering time, there is a conspicuous leaf rosette remaining at the base of the shoot.

The inflorescence is short, dense terminal raceme with 10–25 flowers. The prophylls are caducous. The flowers are bisexual, and often blue, rarely rose red or white. The calyx is five-leaved. Two of the innermost sepals are large, petaloid and obscurely veined. The outermost sepals are small and blue-green. The corolla is tubular and three-lobed. The upper lobes are rounded at the apex. The lowest lobe is keeled and lobed at the apex. There are eight stamens in two clusters in a flower.

The fruit is a cordate, compressed, broadly alate capsule.
