Shiraneginsin (English name) Tilingia ajanensis Regel

Japanese: シラネニンジン（英語表記）Tilingia ajanensis Regel

A perennial plant of the Umbelliferae family that grows in sunny alpine grasslands (illustration). The Japanese name comes from the fact that the leaves are finely divided like carrots and that they were common on Mt. Shirane in Nikko. The stem is upright, 7-40 cm tall, and hairless overall. The basal leaves are finely divided into three pinnates, with terminal lobes 1-3 mm wide. The leaves on the stem become smaller toward the top, and are divided into one or two pinnates. Many flowers bloom in small compound umbels at the ends of the stems from August to September, and the inflorescences have one or two linear involucre bracts.

高山の日当りのよい草地に生えるセリ科の多年草（イラスト）。和名は葉がニンジンのように細かく切れ，日光の白根山に多かったことに由来する。茎は直立して高さ7～40cm，全体に毛がない。根生葉は3回羽状に細かく切れ込み，終裂片は幅1～3mm。茎につく葉は上に行くにしたがって小型になり，1～2回羽状に分かれている。花は8～9月ころ，茎の先に小型の複散形花序を作って多数つき，花序には1,2個の線形の総苞片がある。
