Two new synonyms for Chaerophyllum bulbosum based on morphological, anatomical and molecular data

The aim of the present study was to determine support for reducing Chaerophyllum karsianum and C. posofianum, both local endemic to northeast Anatolia, to the synonym C. bulbosum. Chaerophyllum karsianum is closely related to C. bulbosum but distinguished from it by its pink petals, ciliate bracteoles, entire leaf segments, and 12–16 rays according to the protologue and Flora of Turkey and the East Aegean Islands. Chaerophyllum posofianum is also closely related to C. bulbosum but is distinguished from it by its entire leaf segments, ciliate bracteoles, and purple anthers. Flower color of C. bulbosum ranges from white to purple within the same populations or even within the same individuals. The bracteole margin ranges from entire to ciliate in C. bulbosum. Our field observations and examination of herbarium specimens showed that morphological characteristics overlap in all of the examined samples. We also investigated and compared the anatomical and micromorphological characteristics o...本研究旨在验证将两种安纳托利亚（Anatolia）东北部特有种——卡尔斯峨参（Chaerophyllum karsianum）与波索夫峨参（C. posofianum）处理为球根峨参（C. bulbosum）异名的合理性。根据原始发表文献（protologue）及《土耳其及东爱琴海群岛植物志》（Flora of Turkey and the East Aegean Islands），卡尔斯峨参与球根峨参亲缘关系紧密，但其凭借粉色花瓣、具缘毛小总苞片（ciliate bracteoles）、全缘叶裂片（entire leaf segments）以及12~16枚伞辐（rays）与后者相区分。波索夫峨参同样与球根峨参亲缘相近，可通过全缘叶裂片、具缘毛小总苞片以及紫色花药与后者区分。球根峨参的花色在同一种群内乃至同一植株上均可呈现从白色至紫色的渐变，其小总苞片边缘可呈现从全缘至具缘毛的变化。本研究的野外观察与腊叶标本（herbarium specimens）检视结果显示，所有受试样本的形态特征均存在重叠。本研究同时对上述类群的解剖学与显微形态学特征展开了调查与比较……
