Rumex aquaticus is a flowering plant in the knotweed family, Polygonaceae. It is native to temperate Eurasia.[1] It is commonly known as the Scottish dock, and is found in aquatic environments.[2]
Identification
Rumex aquaticus can be identified by its upright, reddish stout, large heart-shaped leaves to 45 cm long around the base, and smaller leaves around the stalk. It can grow to about 2 m tall.[3] When flowering, Rumex aquaticus can be identified by its red, pink, and green 3 sepal flowers surrounding the stalk.
It can hybridise with several other species of Rumex, most particularly R. obtusifolius (Rumex × platyphyllus), but also with R. crispus (Rumex × conspersus) and R. sanguineus (Rumex × dumulosus).[2][3][4]
Habitat
Rumex aquaticus is native to temperate Eurasia, from Britain and France east to Japan and eastern Siberia;[1] in Britain it is very rare, restricted to a small area around the south end of Loch Lomond.[2] It is a waterside plant, needing nutrient rich, wet soil to grow, including lakesides, sides of streams and rivers, or any other environment with access to shallow water.[2][3]
Distribution
Rumex aquaticus is a hermaphrodite (both male and female) and is pollinated by wind.[5] The seeds require a moist environment for germination but cannot germinate if submerged in water.
