摘 要 ：天南星属 Arisaema Martius是天南星科一个相当进化的大属，现已记录151种[1—10]这里我们试图在阐明属下类群系统关系的基础上，分析本属的发生、扩散和分化历程，探索它的起源中心和起源时期，确定它的现代分布中心和分化中心。

Abstract:The genus Arisaema is one of the large genera of Araceae. At present 151 species have been recognised, of which 139 species or 92% have been collected from Asia, 6 from eastern Africa, 6 from eastern North America, but none have been found from Australia, Europe or from South America, This may serve as an indication of its Laurasian origin centering in Asia.
