Botanical name: Primula gambeliana Family: Primulaceae (Primrose family)
Gambel's Primrose is a delicate perennial herb with an umbel of few violet-purple flowers with notched petals.

The inflorescence doesn't have powdery coating found in many similar species. Flowers are pink-purple or violet purple, with a yellow or dull throat, limb 1.5-2.5 cm wide. Petals are broadly obovate, deeply notched, often toothed at tip. Sepal cup is tubular-bell-shaped, 5-6.5 mm, parted to 2/3--3/5, sepals lanceshaped. Gambel's Primrose is found in moss-covered crevices of wet cliffs in the Eastern Himalayas, from E Nepal to Arunachal Pradesh, at altitudes of 3600-4300 m. Flowering: June-July.
