Polygonum debile / Miyamatanisoba ミヤマタニソバ

 
Polygonum debile, an annual of the height of 10-50cm with some retrorse hairs on nodes, grow in colonies in forests in mountainous regions. Leaves are of alternate phyllotaxis; lower leaves have long pedicles, but upper ones do not. The leaf blades are triangular with the length of 2-5cm and entire, and also with a V-shaped blackish stache on each surface. A few small petal-less white flowers come on each bi-forked peduncle emerged from leaf axils; sepals are cleft in five lobes. Bloom time: August-September.
