蓝钟花属

蓝钟花属(学名:Cyananthus)是桔梗科下的一个属,为多年生、矮小草本植物。该属共有约30种,分布于喜马拉雅区和中国西南部横断山地区。与党参属为姊妹类群 。

蓝钟花属依据花冠形态、花冠被毛式样和生长习性被分成3个组,即宽瓣组、多年生组和一年生组 。蓝钟花属起源于晚中新世,起源地可能为青藏高原地区,位于此地的为宽瓣组。然后该属向横断山迁移,演化成了多年生组和一年生组。其中,多年生组仍处在激烈分化之中。该组(多年生组)的多数类群发生了性别分离,在这些类群中雌性个体和两性个体共存于同一种群中,即表现为雌全异株(Gynodioecy)的性系统。

Cyananthus 蓝钟花属

Cyananthus is a genus that consists of about 30 species of annual or mostly perennial herbs from high mountains of Central and East Asia. They are little Himalayan plants not higher than 4in. The name comes from the Greek for blue flowers. Leaves are usually small and simple, sometimes narrowing to base, tooth-lobed at summit. In August to September, the plants bear showy of bright purplish-blue, yellow or white, funnel to bell-shaped, 5-lobed flowers 1in in diameter with stamens free from the corolla and hairy throat. The flowers are borne singly on stalks. They always lose the aerial parts during the coldest months, and as spring begins, stems and leaves quickly start to reproduce.
