Primula hookeri is occurring in SE Xizang, NW Yunnan of China, Bhutan, NE India, Myanmar, Nepal.
Herbs perennial, base with overlapping bud scales; scales reddish, ovate to oblong, 0.5-2 cm long. Leaves subsessile, 1.5-3.8 cm long, 6-13 mm wide, slightly emergent from basal scales at anthesis, up to 15 cm long, 5 cm wide and distinctly petiolate at fruiting; leaf blade oblong-obovate to spatulate, tapering to base, apex rounded to obtuse. Scapes less than 3 mm tall, included in leaves, elongating to 30 cm tall in fruit, sparsely glandular; umbels 2-3-flowered; bracts linear to subulate, 5-8 mm long. Pedicel 1-2 mm long, glandular. Flowers homostylous. Calyx broadly campanulate or poculiform, 5-8 mm, minutely glandular, parted nearly to middle; lobes suborbicular to rectangular, glandular ciliate, margin denticulate. Corolla white; tube ca. 8 mm long; limb 7-10 mm wide; lobes oblong nearly erect, subtruncate or slightly emarginate at apex. Stamens inserted at middle of corolla tube.

Primula hookeri (commonly known as Hooker's primrose) is a perennial species of primrose which is found at the altitudes of 3,900–5,000 metres (12,800–16,400 ft) in Eastern Himalayas as well as in Bhutan, Myanmar, Nepal, Northeast India[1] and southeastern Tibet and northwestern Yunnan provinces of China.[2]
The species' leaves are subsessile, are 1.5–4 centimetres (0.59–1.57 in) by 0.6–1.5 centimetres (0.24–0.59 in) and are slightly emergent from basal scales at anthesis. The scales themselves are 0.5–2 centimetres (0.20–0.79 in) long, reddish in color, and are oblong and ovate. The scapes' length is less than 3 millimetres (0.12 in) which includes the leaves which become elongated near the fruit part. Corolla is with a stamen and is white or bluish-violet in color with 7–8 millimetres (0.28–0.31 in) long tube and 7–10 millimetres (0.28–0.39 in) wide limb. P. hookeri have an oblong and nearly erect lobes which are subtruncate and a little bit emarginated at the apex. The bracts are linear and subulate and are 5–7 millimetres (0.20–0.28 in). The pedicel is glandular and is 1–2 millimetres (0.039–0.079 in). Flowers homostylous. Calyx is broadly bell-shaped, is minutely glandular and is 5–8 millimetres (0.20–0.31 in) long, but parted near the middle.[2] Flowers are of yellow color.[3]
