Persicaria prostrata, basionym Polygonum prostratum, is a species of flowering plant in the family Polygonaceae, native to Australia [3] and perhaps New Zealand. [4] It is known by the common name of creeping knotweed. [5]
Description
Decumbent perennial herb with stems up to about 40 cm long. [5] Leaves lanceolate to narrowly elliptic, 1–5 cm long, 3–10 mm wide with short hairs on the margins and main veins. [5] [6] Ochreas lobed with hairs 1–2 mm long. [5] [6] Compact short cylindrical flower spikes from 0.6–4 cm long and 4–7 mm diameter. [6]
Ecology
Persicaria prostrata grows on banks of streams, ground-tanks and ditches [6] and on heavy soils in areas prone to inundation. [5]
Taxonomy
The plant was first described in 1810 by Robert Brown as Polygonum prostratum, [7] [8] but was assigned to the genus Persicaria by Jiří Soják in 1974. [1] [2]
