Persicaria decipiens, commonly known as slender knotweed, is a species of flowering plant native to Australia and Asia.[2]
Persicaria decipiens is a trailing plant whose stems grow horizontally at first but become more vertical with time,[3] reaching 30 cm (1 ft) high. Its narrow elliptic to lanceolate (spear-shaped) leaves are 5–12 cm (2–4.5 in) long and 0.5–1.3 cm (0.20–0.51 in) across.[2] The slender pink flower spikes appear from November to June, with a peak in February.[3] Cylindrical in shape, they are not stiff and tend to bend over.[2] The plant tends to die back in winter and regenerate after water.[3]
Persicaria decipiens was among the plants collected by Joseph Banks and Daniel Solander on 5 May 1770 at Botany Bay during the first voyage of Captain James Cook.[4] Prolific Scottish botanist Robert Brown described the species as Polygonum decipiens in his 1810 work Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[5] It was given its current name by Karen Wilson in 1988 as the broadly defined genus Polygonum was split into smaller genera.[4] Common names include slender knotweed, willow weed and snake root.[6]
P. decipiens is found in water and wet soil. It is found across Africa and the Mediterranean,[6] through southwestern Asia, Malesia and all states of Australia, as well as Norfolk Island, New Zealand and New Caledonia.[2] It has become naturalised in Madagascar.[6]
Likely pollinators of its flowers are insects, including honeybees, native bees, flies, wasps and small butterflies.[3]
Persicaria decipiens is not cultivated but is eaten locally in times of famine in Africa.[6]

Синонимы
Persicaria decipiens (лат.) — вид травянистых растений рода Персикария (Persicaria) семейства Гречишные (Polygonaceae), встречается от Австралии до Азии[2]. Ранее вид относили к роду Горец, как Polygonum decipiens.
Стебель Persicaria decipiens поначалу стелющийся и растущий горизонтально, со временем становится восходящий, достигает до 30 см в высоту.[3] Листья узкие эллиптические либо ланцетные, 5,0—12,0 см длиной и 0,5—1,3 см шириной[2].
Цветёт в ноябре — июне, с основным периодом цветения в феврале.[3] Цветки мелкие розовые, собраны в колосовидные кисти с поникающие верхушкой.[2]
Растение отмирает в засушливый период и регенерирует с появлением воды.[3]
Образцы Persicaria decipiens были впервые собраны 5 мая 1770 года Джозефом Бэнксом и Даниэлем Соландером в Ботаническом заливе во время первого путешествия Джеймса Кука.[4] Шотландский ботаник Роберт Браун описал вид как Polygonum decipiens в своей работе 1810 года Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[5] Современное название виду было дано Карен Уилсон в 1988 году после того как большой род Polygonum был разделён на несколько родов.[4]
Произрастает от Африки и Средиземного побережья через юго-западную Азию, Малайзию до Австралии, Новой Зеландии и Новой Каледонии.[2] Натурализован на Мадагаскаре.[6]
Persicaria decipiens растёт в воде и на сырых местах.
Опыляется насекомыми, включая пчёл, мух, ос и мелких бабочек.[3]
Persicaria decipiens не культивируется, но используется в пищу в Африке в случае голода.[6]
