胡椒属(Piper)为胡椒科(Piperaceae)重要的泛热带组成成分,约有1000~2000个植物种类,中国是其天然分布的北缘。本文对我国产胡椒属植物区系地理进行了分析,揭示其区系特征、物种起源和散布途径等。结果表明:云南是我国胡椒属植物的重要分布地,并以此为中心向我国东部和北部扩散,物种数量逐渐减少。各省胡椒属物种组成相似性较低,大致可被聚为热带地区、亚热带地区和台湾地区3大分支。 在区系成分上,国产胡椒属植物中的中国特有比例最高,其次是热带亚洲分布,只有个别种为泛热带分布和东亚分布。我国胡椒属区系与中南半岛、印度半岛及爪哇群岛存在一定联系,但并不紧密。分析认为,云南是胡椒属植物的起源中心或分化中心之一,而中国台湾岛种类主要由菲律宾群岛等传入并分化。本结果对于研究该属系统分类和起源演化将具有一定意义。

 Piper is the largest genus and important Pantropical components of the Piperaceae family with approximately 1000-2000 species in the world. China is in the northern verge of its natural distribution. In this study, floristic geography of the Piper genus in China was analyzed to reveal its botanical characteristic, origins of speciation and its dispersal channels. The study results showed Yunnan province is one of the very important distribution regions for Piper species, served as the center of the Piper species dispersal toward to the eastern and northern regions of China with gradually reduced species numbers. The similarity level appeared to be low for its species among different provinces, and the Piper distribution regions could be approximately clustered into three clades: tropical clade, subtropical clade and Taiwan clade. Cladistically, Piper species found in China have the highest proportions which were endemic to China, and then followed by Piper species distributed in Tropical Asia, only few species belonged to Pantropical and East Asia arealtypes. The floristic geography of Piper genus in China is related to that of IndoChinese Peninsula, Java Islands and Indian Peninsula in some degrees, but not closely related. This study revealed Yunnan province is one of the central of origins for the Piper species, and or one of the central of regions for its species diversification, and the Piper species of Taiwan mainly came from Philippine islands and further diversified into Taiwan clade. Our study results presented a useful method for the systematic studying of Piper genus taxonomy and the evolution of Piper speciation.
