Smartweed (water pepper)
Polygonum hydropiper

Annual. The branched stem, 2 to 3 feet in length, creeps at first, then becomes semi-erect. The leaves are lanceshaped, shortly stalked, wavy, more or less acute, glandular below, fringed with hairs. The stipules form a short inflated ochrea. The greenish-pink flowers are in long, slender, loose racemes, that mostly droop at their tips. There are six to eight stamens, two of which are functionless; two to three styles to the pistil. The fruit is black and dotted, as long as the perianth, three-sided and nut-like. The leaves have a pungent, acrid, bitter taste (something like peppermint), which resides in the glandulat dots on its surface, no odour.
