在标本和文献综合分析的基础上,对世界范围内孩儿参属(Pseudostellaria Pax)植物的主要形态特征进行了总结,依据Mizushima的分类系统编制了孩儿参属的分类检索表,对5个存疑种进行了初步分类处理,并对孩儿参属各种类的分布状况进行了绘图和分析。结果表明:具有肉质块根、绝大多数种具有闭锁花以及开放花花瓣常呈2浅裂是孩儿参属区别于石竹科(Caryophyllaceae)其他属的典型特征。初步确认全世界的孩儿参属植物共22种,被分成Sect. Pseudostellaria和Sect. Mamillatae2个组,其中,前者仅包含石生孩儿参[P. rupestris (Turcz.) Pax]1种,而后者则被进一步分成Ser. Mamillatae和Ser. Distantes2个系。本...

On the basis of comprehensive analysis on specimens and documents, main morphological characteristics of species in Pseudostellaria Pax in the world were summarized, key to Pseudostellaria was compiled according to Mizushima infrageneric classification system, five impeach species were preliminarily classified, and distribution status of species in Pseudostellaria was plot and analyzed. The results show that typical characteristics of species in Pseudostellaria differing from other genera in Caryophyllaceae are having flesh root tuber, vast maj...
