Japanese: マツムシソウ - まつむしそう
Scabiosa - Scabiosa

A biennial plant of the family Diapathaceae (APG classification: Caprifoliaceae). The stem is 30-80 cm tall. The leaves are opposite and pinnately lobed. From August to October, pale purple flower heads open upward at the end of a long stalk. The outer florets of the corolla are lip-shaped and have five lobes, while the central floret is tubular and has four equal lobes. It grows in the pampas grasslands of hills and mountains, and is distributed from Hokkaido to Kyushu. It is named after the environment where it grows, resembling the chirping of pine crickets. A variant of the plant, Ezomatsumushisou, with sharply pointed leaf lobes, is distributed in northern Honshu and Hokkaido. The genus Diapathus has leathery bracts, 4-5 lobes of the corolla, and small bracts that encase the calyx and spread out in a cup- or funnel-like shape. There are about 70 species worldwide and two species in Japan, and the flowering plant is cultivated.
