The number of chromosomes is 2n = 24.

Distribution and location requirements

The natural range is in the West Himalayas in the east of Afghanistan, in India in the union territories of Jammu and Kashmir and Ladakh as well as in the state of Himachal Pradesh and in the north of Pakistan. The false parrotia grows in steppes and dry forests on fresh, slightly acidic to slightly alkaline, sandy-loamy to loamy, moderately nutrient-rich soils in light to partially shaded, cool to cold locations. The species is frost hardy . The distribution area is assigned to winter hardiness zone 6b with mean annual minimum temperatures of −20.5 to −17.8 ° C (−5 to 0 ° F).

Systematics

The false parrotia ( Parrotiopsis jacquemontiana ) is the only species of the monotypical genus Parrotiopsis in the witch hazel family (Hamamelidaceae). There the genus is assigned to the tribe Fothergilleae in the subfamily Hamamelidoideae. The species was first scientifically described in 1844 by Joseph Decaisne as Parrotia jacquemontiana ( Basionym ) . Alfred Rehder placed them in the genus Parrotiopsis in 1929 . Another synonym of the species is Parrotiopsis involucrata C. K. Schneid. The generic name Parrotiopsis is derived from the generic name of the ironwood tree Parrotia and the Greek opsis for "appearance". The specific epithet jacquemontiana honors the French explorer Victor Jacquemont (1801–1832).

use

The wood is solid and is used to make handles, walking sticks and bed frames. Baskets are woven from the branches. The species is sometimes used as an ornamental shrub due to its decorative and fragrant flowers and striking autumn colors .
