The Astilbe Buch.-Ham. ex D. Don was founded in 1912. There are
now 18 species throughout the world. USSR, Thailand, Indonesia, Bhutan, Nepal d Kashan-
mir each has only 1 species; Korea, Philippines and USA each has 2; India 3; Japan 6; and
China 7 (including 3 endemics and 1 new variety). And northeast China, north China and
northwest China each has 2; central China and southwest China each 4; eastern China 5.
Thus the distribution centre of this genus seems to be in the region covering Japan and
eastern, central, and southwest China.
This genus is divided into two sections: Sect. Simplicifoliae Engl. and Sect. Astilbe.
Sect. Simplicifoliae may be considered as the primitive one because it has 5 ordinary petals.
This section consists of about 10 species: 5 in China (east China 4; southwest China 3; ce-
ntral China, north China and northeast China each 2; Northwest China 1), 5 in Japan, 2
in Korea, 1 in Philippines and India each. According to the distribution of this section, the
author suggests that the centre of origin of this genus be in the forested parts from Japonthrough east China to southwest China. 相似文献

本文对鬼灯檠属Rodgersia Gray的染色体数、花粉体积和纹饰、萼片数目、萼片脉序和脉型、萼片腹面毛被、花梗和花序轴毛被、叶的类型等关键性状进行了分析,确定了其进化顺序,依据性状的系统发生,绘制了鬼灯檠属的瓦格勒尔系统树;确认本属有5种和3变种,其中以R.podophylla为最原始,R.nepalensis为最进化,而R.aesculifolia,R.sambucifolia.和R.pinnata则居于两者之间。本属分两组Sect.Rodgersia,仅含R.podophylla Sect.Sambucifolia J.T.Pan,含R.aesculifolia,R.sambucifolia,R.pinnata,R.nepalensis。依据种的主要分布区,划本属植物为4个分布类型,即:日本—朝鲜间断分布,秦岭—大巴山分布,横断山分布和东喜马拉雅分布。笔者认为,本属的起源地在日本-朝鲜一带,横断山地区是其现代分布中心和分化中心;本属的散布路线是自日本—朝鲜,经秦岭—大巴山,通过横断山地区而进入东喜马拉雅,本属的起源时间,当在晚第三纪以前(晚白垩世至早第三纪)。此外,还报道了鬼灯檠属植物的花粉形态。 相似文献
