Abstract:Polyspora Sweet are evergreen tree of Theaceae with 50 species,mainly distributed in South Asia and Southeast Asia. Polyspora have high ornamental value,can be used as landscape trees in tropical and subtropical regions. Some of them have edible and medicinal values. Based on the brief introduction of the germplasm resources and application of the genus Polyspora,the research progress of its systematic evolution and taxonomy,reproductive characteristics,physiological characteristics,ecological habits,seedling technology,chemical components and pharmacological activities were reviewed in detail. This review point out that in the future,we should expand the research scope and species of the genus,and strengthen the germplasm resources collection,phylogeny,genetic diversity and so on. We should pay more attention to the introduction,cultivation,and germplasm innovation of the genus,and fully explore its medicinal value,and carry out clinical research. This review paper will provide theoretical basis and reference for further research of Polyspora plants.

大头茶属(Polyspora Sweet)隶属于山茶科(Theaceae)山茶亚科(Theoideae)山茶族(Theeae),由Sweet于1826年创立。大头茶属与山茶科其他属的形态差异在于:花瓣与萼片没有明显区别,雄蕊基部与花冠合生,木质蒴果开裂成五瓣,种子具大的顶翅(Orel et al.,2012)。
大头茶属植物是良好的城乡绿化树种,其树形优美,花期10月至次年1月,在园林中可作庭荫树、行道树,也可作丛植观赏。大多数种类能够适应贫瘠山地,抗风与再生能力强,可作为我国南方荒山绿化的先锋造林树种。大头茶属植物……
