Kariyasu (Kariyasu) - Kariyasu

Japanese: カリヤス(刈安) - カリヤス

A perennial grass of the Gramineae family that grows in sunny areas in the mountains of central Honshu. The stems are thin and sparsely arranged, growing to a height of about 1m. The inflorescences that appear from August to October are divided into 3 to 10 branches (general), each of which has densely packed, spiny spikelets. In the past, it was cultivated to extract yellow dye from the stems and leaves. Note that the plant called Kariyasu on Hachijojima is not this species, but Kobunagusa.

本州中部の山地の陽地にはえるイネ科の多年草。茎は細く，まばらに束生し，高さ1m内外。８〜10月につく花穂は３〜10本の枝（総）に分かれ，それぞれに，のぎのない小穂を密生。古くは茎や葉から黄色の染料をとるために栽培された。なお，八丈島でカリヤスと呼ぶのは本種ではなく，コブナグサである。
