摘要

根据形态学和细胞遗传学研究，本研究描述并说明了产自印度马哈拉施特拉邦纳西克地区 Anjaneri 山的一种菊科植物 Senecio（菊科，Senecioneae）新种 Senecio anjanericus。该物种与 Senecio bombayensis 相似，但不同之处在于叶舌较小，茎上有明显的叶状辅助苞片和致密的毛被。体细胞染色体数为 2n = 2x = 20，所有染色体的中心粒均位于中间区域。本文提供了该新种的详细形态描述、插图和核型特征。

A new Senecio (Asteraceae) from the Anjaneri Hills of Nashik, India

A new species of Senecio (Asteraceae, Senecioneae), Senecio anjanericus is described and illustrated from the Anjaneri Hills of Nashik district, Maharashtra, India, based on morphological and cytogenetical studies. The species resembles Senecio bombayensis, but differs from it in small size of the ligules, presence of conspicuous foliose supplementary bracts and dense indumentum on stem. The somatic chromosome number was observed to be 2n = 2x = 20, with all the chromosomes exhibiting median region centromeres. A detailed morphological description, illustration and karyotypic features of the new species are provided.
