The head primrose occurs in the Himalayas and from northern Myanmar to the Chinese province of Yunnan . It grows in coniferous forests and on marshy river banks on moist clay at altitudes of 4,000 to 5,000 meters.
Systematics
Primula capitata was in 1850 by William Jackson Hooker in Curtis's Botanical Magazine , Volume 76, table 4550, first described . A synonym for Primula capitata is Primula sphaerocephala Balf.f. & Forrest .
There are three known subspecies:
- Primula capitata subsp. crispata : The underside of the leaves is floury and white. The inflorescence is disc-shaped. The subspecies occurs in Bhutan , northeast India , Sikkim and southern Tibet in mountain forests and on grasslands at altitudes of 2700 to 5000 meters.
- Primula capitata subsp. lacteocapitata ( Balf.f. & WWSm. ) WWSm. : The underside of the leaves is cream or light yellow and floury. The inflorescence is spherical. The subspecies occurs in northeast India, Sikkim and southern Tibet in forest fringes and in meadows at altitudes of 3000 to 5000 meters.
- Primula capitata subsp. spaerocephala ( Balf.f. & Forrest ) WWSm. & Forrest : The underside of the leaf is not floury. The inflorescence is spherical. The subspecies occurs in China in southeast Tibet and in Yunnan on river banks and in clearings in spruce forests at altitudes of 2800 to 4200 meters.
