This is a squat plant with a thick rhizome covered with blackish remains of old petioles. Stems are thin, somewhat branched, covered with scattered reflexed hairs with some glandular hairs, 5-10cm long.

Leaves are bipinnately divided, oblong, 4-7cm long, 1-1.5cm wide. Lobules are numerous, linear.

Inflorescence: Umbels bear a few small flowers in June, petals are purple with a narrow claw, sepals ovate, densely glandular pubescent, with almost no mucro, anthers are yellow. Beak 4-5cm.

Distribution: Found on alpine pastures of the extinct volcano Ziaret Agmaganskogo (Geghama) range and Aragats mountain range, Armenia at 2400-3000m. Critically Endangered
