世界红树植物区系

探讨了世界红树林植物区系的种类组成及其特点。确认全世界共有红树植物16科24属84种(含12变种)，其中真红树为11科16属70种(含12变种)，半红树为5科8属14种。东方类群有14科18属74种(含12变种)，以／legiceras，Osbornia，／legialitis，Bruguiera，Ceriops，Kandelia，Scyphiphora和。Nypa等属为特征；西方类群有5科6属10种，具有单种特有科皮利西科Pelliceraceae以及laguncularia属。中国红树植物区系有12科15属26种(含1变种)，其中特有种4种。海南的红树植物种类最为丰富，占全国的96．2％；广东次之，占42．3％。台湾记载的红茄苳(Rhizophoram,ucronata)其实为红树榄R．stylose之误。

Mangrove Flora of the World

The species composition and characteristics of mangrove flora in the world were reviewed and discussed. The results suggested that the world's mangrove plants have 84 species (including 12 varieties) in 24 genera and 16 families. Of which, true mangrove plants have 70 species (including 12 varieties) in 16 genera and 11 families, and semi_mangrove plants 14 species in eight genera and five families. The Eastern Group has 74 species (including 12 varieties) in 18 genera and 14 families, characterized by the genera Aegiceras , Osbornia , Aegialitis , Bruguiera , Ceriops , Kandelia , Scyphiphora and Nypa etc. The Western Group has only 10 species in six genera and five families, characterized by the endemic one_species family, Pelliceraceae, and the genus Laguncularia . The mangrove flora of China is composed of 26 species (including one variety) in 15 genera and 12 families, four of which are endemic. Hainan is most rich in mangrove species, making up about 96.2% of the Chinese total; Guangdong ranks second, making up about 42.3%. It has been demonstrated that Rhizophora stylosa was mistaken for R. mucronata in Taiwan by previous authors.
