Magnolia biondii (Biond’s Magnolia) is a deciduous tree that flowers in late winter to early spring before leaf growth. Its early flowering nature gives it the name of the Hope for Spring Flower. It is a member of the magnoliaceae family, which consists of more than 210 species. Furthermore, it is widely found in northern China. It produces small white flowers every few years. Leave buds and petals of the plant are used to alleviate nasal obstruction and coughing in some parts of China.
Distribution
Magnolia biondii is widely distributed in China. It is commonly found in Gansu, Henan, Hubei, Shaanxi, Sichuan provinces. It is usually found in forests in the mountains. The plant was discovered and introduced to the Western hemisphere more than 70 years ago. [1]
Habitat and ecology
Magnolia biondii is a deciduous tree that grows mainly in temperate forests in the mountains.It has a broadly conical to spreading habit. [1]
Morphology of leaf
Magnolia biondii can grow up to 40 feet, or 12 meter. Its bark has a pale gray and smooth appearance. It produces simple leaf type with ovate shape. In general, leaf size varies and can be up to eight inches, or 20 centimeters, long and four inches, or ten centimeters, across. In addition, they are taper-pointed at the tip and wedge-shaped at the base with a short petiole of up to ¾ inches, or 2 centimeters. [1] Furthermore, leaves are arranged in an alternative pattern. Leaves have pinnate venation. Moreover, stamens and carpels are spirally arranged. [2]
Flowers and fruit
Flowers of Magnolia biondii are small and white and have strong fragrance associated to them. They can grow up to 3 ¼ inches, or eight centimeters across. Flowers parts are in sets of threes. In general, flowers have six petals and three sepals. More specifically, the petals are pink at the base and white at the top. [1] Furthermore, flowers have cone-shaped receptacle that bears spirally arranged carpels from which styles emerge. [2] Stamens are cream-white in color. In addition, flowers take several years to appear. Because of the small size and long growth period, Magnolia biondii is seldom used for ornamental purposes. Magnolia biondii produce aggregate fruits that consist of numerous separate carpels of one gynoecium. The fruits form in cylindrical cluster and protrude on a stalk. Each cluster can grow up to 5 ½ inches, or 14 centimeters long. Individual fruitlets are red at first, then turn brown upon maturity. [1]
Usage
Food
Dried flower buds and petals of Magnolia biondii are considered food in some parts of China. Fresh flower buds can be prepared by mixing with vinegar and ginger. Petals can be fried with flour batter coating. [3]
Medicinal
The dried flower buds of Magnolia biondii are used medicinally in China and Japan. [4]They are used to relieve coughing and nasal obstruction. Pharmacologically, five lignans including pinoresinol dimethyl ether, magnolin, epi-magnolin A, fargesin, and demethoxyaschantin have been attributed to the medicinal effect of Magnolia biondii. [5]
Similar species
Magnolia biondii is closely related to the Japanese Willow-Leaf Magnolia, Magnolia salicifolia, which has aromatic foliage and shoots. Resemblance is also observed in Magnolia dendata. Magnolia biondii is generally distinguished by its smaller size, narrower leaves, and smaller flowers. [1]
