Kyllinga Brevifolia (Kyllinga Weed) 姫莎草（ヒメクグ）

Japanese follows English. 英語の後に日本語が続きます。

These are inflorescences of Kyllinga brevifolia or more commonly kyllinga weed. They're a weed, but because of their tininess (less than 1 cm in diameter) and spiky shape, adorable. I had to squat down to take these photos and that was a good exercise😁.
