description

leaves

The Chinese false hazel is a shrub up to 5 meters high with bare or downy hairy shoots. The leaves are divided into a petiole and a leaf blade. The stem is 5 to 10 millimeters long and tomentose with star hairs . The stipules are 20 millimeters long, narrow-elongated and sparsely hairy. The leaf blade is simple, oblong-obovate, obovate, obovate-rounded or broadly ovate, 3 to 9 centimeters long and 2 to 6 centimeters wide, with a blunt, pointed or long pointed tip, with a slate, heart-shaped or more or less truncated base and indented and prickly serrated leaf margin. Seven to nine pairs of nerves are formed. The upper side of the leaf is glabrous or hairy along the veins , the underside is blue-green and softly hairy.

The inflorescences are 3 to 4 centimeters long clusters of 10 to 18 flowers on 1.2 to 1.5 centimeters long, hairy stems. The basal bracts are ovate-round, 8 to 10 millimeters long, dark brown, shaggy inside and hairy outside. The bracts of the single flowers are egg-shaped, 4 to 5 millimeters long and hairy downy. The bracts are oblong and 2 to 3 millimeters long. The flower cup is star-haired. The sepals are ovate, glabrous with a more or less blunt tip. The lemon-yellow petals are spatulate, 5 to 6 millimeters long and 3 to 4 millimeters wide. The stamens are 5 to 6 millimeters long and yellow. The scales of the disc are bilobed, pointed and about as long as the petals. The ovary is covered with star hairs, the styles are 5 to 6 millimeters long and hairy at the base. The capsule fruits are 10 to 14 millimeters long, 7 to 9 millimeters wide and hairy in a star shape. The seeds are 4 to 5 millimeters long. The Chinese false hazel blooms from April to July.

Occurrence and location requirements

The natural range is in China in the provinces of Anhui , Fujian , Guangdong , Guangxi , Guizhou , Hubei , Hunan , Jiangxi , Sichuan and Zhejiang . The Chinese false hazel grows in steppes and dry forests at an altitude of 1000 to 1500 meters on fresh, weakly acidic to weakly alkaline, sandy-loamy to loamy, moderately nutrient-rich soils in light to partially shaded locations. The species loves warmth and is moderately frost hardy .

Systematics

The Chinese Winter Hazel ( Corylopsis sinensis ) is a kind from the kind of corylopsis ( Corylopsis ) in the family of hamamelidaceae (Hamamelidaceae). There it is assigned to the tribe Corylopsideae in the subfamily Hamamelidoideae. William Botting Hemsley first described the art in 1906 in the Gardeners' Chronicle . The generic name Corylopsis is derived from Corylos , the generic name of the hazel , and from the Greek word "opsis" for "appearance". It corresponds to the German name Scheinhaseln and refers to the similarity of leaves and inflorescences with those of hazelnuts. The specific epithet sinensis comes from the Greek, means "Chinese" and thus describes the origin of the species. A synonym of the species is Corylopsis spicata Hemsl. , a name that should only be used for the corn hazel ( Corylopsis spicata Siebold et Zucc. ).

There are two varieties :

  • Corylopsis sinensis var. Sinensis with hairy shoots and buds and an obovate to obovate, rounded leaf blade. The upper side of the leaf is glabrous or hairy along the veins, the underside is gray-brown, star-haired. The variety blooms from May to July, the fruits ripen from July to September. The distribution area is in the Chinese provinces of Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangxi, Sichuan and Zhejiang.
  • Corylopsis sinensis var. Calvescens Rehder & EH Wilson with bare shoots and buds and a broadly ovate to oblong obovate leaf blade with a slate, heart-shaped or more or less truncated base and pointed or pointed tip. The upper side of the leaf is glabrous, the underside glabrous or hairy only along the leaf veins. The variety blooms from April to July, the fruits ripen from July to September. The distribution area is in the Chinese provinces of Guangdong, Guangxi, Guizhou, Hunan, Jiangxi and Sichuan.

use

The Chinese false hazel is rarely used as an ornamental shrub because of the decorative and fragrant flowers and the impressive autumn color .
