Where is the latest origin of crane grass?

Crane grass, alias Tuli grass, melon vanilla, old cow tendon, wolf sprout grass and so on, is a perennial herb of Rosaceae. The dry aboveground parts of the plant remove residual roots and impurities, wash and dry and can be used as medicine. It has the functions of converging hemostasis, stopping malaria, stopping dysentery, detoxification and tonifying deficiency. Let's take a look at where the celestial crane grass is produced.

Where is the origin of crane grass?

Crane grass up to 1 meter high, the whole plant has white long hair, short rhizome, often 1 or more root buds, erect stem, pinnately compound leaves alternate, raceme terminal, calyx inverted conical, petal yellow, calyx tube thickened and drooping when the fruit is ripe, with a round of upright thorns at the top, very similar to the head of the crane, so it is called crane grass, flowering from May to December, the producing area is mainly located in Jiangsu, Zhejiang, Hubei and other places, and also produced in other parts of the country.

The environment of the origin of Herba Euphorbiae

Crane grass likes the warm and humid environment, the suitable growth temperature is 20: 30 ℃, and the soil requirements are not strict, but it is better to plant seeds or split roots in sandy loam with deep soil layer and loose and fertile soil. Spring sowing in late March in the south, mid-April or late April in the north, autumn sowing in the south from late September to early October, and north from late October to early November before ground freezing, root reproduction can be carried out in spring and autumn.

The Variety Classification of Herba Euphorbiae

2. European dragon bud grass: European dragon bud grass leaflet sessile or occasionally short stalked, oval, oblong or Obovate elliptic. Stipules broad, herbaceous, semiorbicular, margin thickly acute serrate or shallowly lobed. Inflorescences usually unbranched, inflorescence rachis thick, pubescent and villous, pedicels very short, petals yellow. Fruit campanulate, sparsely pilose, with several layers of hooks at the top. Flowering in June, fruiting in July. The producing areas are distributed in Xinjiang, China, and also in central and southwestern Asia.

3. Japanese dragon bud grass: the main root of Japanese dragon bud grass is thick and short, the rhizome is slightly longer, and there are often underground buds at the base. The stem is 30-90 cm tall, the upper part is densely pubescent and the lower part is densely yellow hirsute. Leaves are intermittent odd-pinnate, petiole sparsely pilose and pubescent, leaflets sessile or shortly stipitate. Inflorescences usually branched, slender, flowers small. The fruit is small, calyx tube bell-shaped, hemispherical, flowering and fruiting from August to November. The producing areas are also distributed in Anhui, Zhejiang, Guangdong, Guangxi, southeastern Guizhou, Jiangxi and northern Laos.

4. Rabdosia angustifolia: the stem is thick, the stem is 30cm high and 100cm high, and the stem, petiole, leaf axis and inflorescence axis are all villous and pubescent. The leaves are irregular odd-pinnate leaves, the upper stipules of the stem are reniform and the lower stipules are lanceolate. Spike racemes born at the top of branches, many flowers, yellow flowers. The fruit is obconical, with hooked bristles at the top, persistent calyx and flowering period from July to September. It originated in the United States, Canada and Europe, and has been introduced and planted in all parts of China.

5. Rabdosia angustifolia: the main root is thick and short, the stem is 30cm high, the upper part is densely pubescent, and the lower part is densely covered with yellow hirsute. Leaves are intermittent odd-pinnate compound leaves, petiole sparsely pilose and pubescent, leaflets sessile or shortly stipitate, stipules falcate or semicircular, lower stem stipules often entire. Inflorescences usually branched, slender. The fruit is small, calyx tube bell-shaped, hemispherical, flowering and fruiting from August to November. The producing areas are also distributed in Anhui, Zhejiang, Guangdong, Guangxi, southeastern Guizhou, Jiangxi and northern Laos.

6. Artemisia angustifolia: the root is stout, cylindrical, and the rhizome is thick and short. Stem 35-120 cm tall, densely hirsute. Leaves are intermittent odd-pinnate, leaflets sessile or occasionally shortly stipitate. Stipules broad, herbaceous, semiorbicular, margin thickly acute serrate or shallowly lobed. Inflorescences usually unbranched, inflorescence rachis thicker, petals yellow-Obovate-elliptic. Fruit bell-shaped, sparsely pilose, flowering in June, fruiting in July. The producing area is distributed in Xinjiang, China. The distribution is rare, and it is also distributed in central and southwestern Asia.
