Pleuropterus multiflorus
species of plant

Pleuropterus multiflorus (syns. Fallopia multiflora, Polygonum multiflorum, and Reynoutria multiflora) is a species of flowering plant in the buckwheat family Polygonaceae native to central and southern China, Hainan, Taiwan, Vietnam, and Thailand. It is known by the English common names tuber fleeceflower and Chinese (climbing) knotweed. It is known as he shou wu (何首烏) in China and East Asia. Another name for the species is fo-ti, which is a misnomer.
It can be difficult to prevent the spread of this vine and to remove it once established. The leaves are thin and fragile but the stems, although narrow in diameter, can be very strong.
Description

The leaves are 3–7 cm (1.2–2.8 in) long and 2–5 cm (0.79–1.97 in) broad, broad arrowhead-shaped, with an entire margin.

Why this record matters
“Pleuropterus multiflorus” is worth following because a concise public description often conceals a longer documentary argument. Here, Pleuropterus, multiflorus and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q50860327. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
