Euphorbia Profile

This genus contains about 2000 species. It is one of the largest genera of angiosperms, which are distributed around the world, especially in Africa and central and South America. There are about 66 species native to China, and another 14 species are grown and naturalized in China, adding up to 80 species.

Euphorbia morphological characteristics

Euphorbia belongs to herbs, shrubs, or trees. It's normally annual, biennial, or perennial. The plant body has an emulsion liquid. Roots terete, or fibrous, or with irregular tuberous roots. Leaves often alternate or opposite, less whorled, often entire, less divided or dentate or irregular. Leaves often without petiole, few with petiole. Stipules often absent, few present or drilllike or spiny.

Euphorbia growth habit and growing environment and distribution

Euphorbia is famous for its variety, complex habitat and great variability. It is one of the most difficult genera in angiosperms classification. Since Linn(1753) established the genus, there has been no worldwide revision work for a long time, and no regional revision work in its main distribution centers (Africa and central and South America), except for the system established by Boisser (1862) in DC.PROdr. The collation of Euphorbia in China was carried out under this background. Euphorbia, a genus under the family Euphorbiaceae, can be found in subtropical and temperate regions. There are more than 60 species in China, which are widely distributed throughout the country. Some species are poisonous, while others have stems and leaves that can be used as medicine. Some are for viewing as well.

Euphorbia efficacy and role

There are more than 60 kinds in China, which are widely distributed throughout the country. Some kinds are poisonous, and some kinds of stems and leaves can be used as medicine. Some are for viewing.

Euphorbia patterns

Variation of this genus is mainly: habits, the ephemeral plant, herb to irrigation and trees, morphologically by leaves (fall) earlier leaf, by alternate to the opposite or verticillate, compound inflorescence branch by ChanQi, dichasial branched or unbranched to multiple disambiguation inflorescence (that is, a single altar), involucre gland 1, 4-5 rings or majority, Abraham for 2-3 pieces, glands appendages exist or not, and seeds with or without caruncle; In addition to the differences in various forms, the range of variation is indeed so striking that it has been divided into several genera. Throughout the research history of this genus, there has been a relatively large number of ideas in favor of no longer dividing. Based on this, this work adopts a great deal of concept.
