It is a variety of the English one - Polygonum aviculare, and has similar properties. It has an upright smooth branched stem and grows from 1 to 3 feet high. Leaves are smooth, broadly obvate, rather obtuse- 1 to 2 inches long - and about half as broad - either sessile or petiolate. Flowers bloom June to September in bunches at axils of the leaves.

---Medicinal Action and Uses---It is highly astringent as an infusion or decoction; useful in diarrhcea as an injection and in children's summer complaints; also as a good gargle and a valuable remedy for inflammatory diseases of the tissues.
