Persicaria orientalis
Persicaria is a genus of flowering plants in the knotweed family, Polygonaceae. Plants of the genus are known commonly as smartweeds.[1] It has a cosmopolitan distribution, with species occurring nearly worldwide.[1][2] The genus was segregated from Polygonum.[3]
Description
The genus includes annual and perennial herbs with taproots or fibrous root systems, and sometimes rhizomes or stolons. The stems are often erect but may be prostrate along the ground, and some species are prickly.[1] The stems are self-supporting or twining and climbing.[4] The leaves are alternately arranged, deciduous, and variously shaped. The brownish or reddish ochrea may be leathery to papery. The inflorescence may be a panicle or a spikelike or headlike arrangement of fascicles of flowers. The flower is white, greenish, reddish, or purple, with the tepals partially fused together along the bases. The fruit is an achene which can take a number of shapes, including a disc or a sphere.[1]

There are about 100[1] to 150 species[2][5] in this genus, depending on how it is defined.[3]
