Pomatosace filicula is a biennial plant that grows from rosettes of basal leaves, each 15–90 millimetres (0.6–3.5 in) long and 6–15 mm (0.2–0.6 in) wide and divided into lobes along its length;[3] the leaves may be reminiscent of a fern, providing the species' epithet, filicula (diminutive of Latin filix, "fern").

Each flower is white, with five petals fused into a tube for around 2 mm (0.08 in).

[3] Pomatosace filicula is only found in the north-eastern part of the Qinghai–Tibetan Plateau,[4] in the Chinese provinces of Sichuan, Xizang (Tibet) and Qinghai.

[3] It grows in a variety of habitats, including alpine meadows and sand flats along rivers, at altitudes of 2,800–4,500 metres (9,200–14,800 ft).

[3] It is thought to have evolved to inhabit the open ground in front of the burrows of plateau pikas (Ochotona curzoniae) and other ground-dwelling mammals.
