Abstract

Parasenecio pentaphylla, a new species of the genus Parasenecio from Mt. Ilwol-san, Ilwol-myeon, Yeongyang-gun, Gyeongsangbuk-do, Korea, is described and illustrated here. In Korea, this species has been recognized as P. adenostyloides, known to be a Japanese endemic species. However, it is clearly distinguished from P. adenostyloides by its involucre shape, the number of phyllaries, the number of florets per capitulum, and the ratio of the tube length to the throat length. A molecular phylogenetic analysis using the Internal Transcribed Spacer region also clearly indicated that P. pentaphyllaria was genetically distinct from P. adenostyloides. Therefore, it is recognized as an independent species, different from P. adenostyloides. The specific epithet “pentaphyllaria” was given based on its characteristic of having five phyllaries.
& lt; i> Parasenecio pentaphyllaria< / i>(菊科:银蕨科)<i>拟银蕨</i>从韩国
<i>Parasenecio pentaphylla</i>,属一新种<i>图为韩国庆尚北道灵阳郡一月面一月山的特产。在韩国,该物种已被确认为<i>P。adenostyloides</i>,已知为日本特有种。然而,它与<i>P有明显的区别。adenostyloides< / i>通过其总苞的形状,叶状花序的数量,每头花序的小花数,管长与喉长之比。利用内部转录间隔区进行的分子系统发育分析也清楚地表明<pentaphyllaria< / i>在基因上不同于P。adenostyloides< / i>。因此,它被认为是一个独立的物种,不同于<i>P。adenostyloides< / i>。“<i>pentaphyllaria</i>”是根据其具有五节的特点而给出的特称。
