Polygonum
''Polygonum'' is a genus of about 130 species of flowering plants in the buckwheat and knotweed family Polygonaceae. Common names include knotweed and knotgrass (though the common names may refer more broadly to plants from Polygonaceae). In the Middle English glossary of herbs ''Alphita'' ( 1400–1425), it was known as ars-smerte. There have been various opinions about how broadly the genus should be defined. For example, buckwheat (''Fagopyrum esculentum'') has sometimes been included in the genus as ''Polygonum fagopyrum''. Former genera such as ''Polygonella'' have been subsumed into ''Polygonum''; other genera have been split off. The genus primarily grows in northern temperate regions. The species are very diverse, ranging from prostrate herbaceous annual plants to erect herbaceous perennial plants. ''Polygonum'' species are occasionally eaten by humans, and are used as food plants by the larvae of some Lepidoptera species – see list. Most species are considered weeds ...

Paspalum Distichum
''Paspalum distichum'' is a species of Poaceae, grass. Common names include knotgrass, water finger-grass, couch paspalum, eternity grass, gingergrass, and Thompson grass. Its native range is obscure because it has long been present on most continents, and in most areas it is certainly an introduced species. Its native range probably includes parts of the tropical Americas. This is a perennial grass forming clumps and spreading via rhizomes and stolons. It grows decumbent or erect to a maximum height near 60 centimeters. The inflorescence is usually divided into two branches lined with spikelets. ''Paspalum distichum'' is a food source for several avian species, including the long-tailed widowbird.

Acronicta Rumicis
''Acronicta rumicis'', the knot grass moth, is a species of moth which is part of the genus ''Acronicta'' and family Noctuidae. It was species description, first described by Carl Linnaeus in his 1758 Lepidoptera in the 10th edition of Systema Naturae, 10th edition of ''Systema Naturae''. It is found in the Palearctic region. ''A. rumicis'' lives and feeds on plants located in wide-open areas. At its larval stage, as a caterpillar, it causes such a large impact as a crop pest that it has received much attention and research. ''A. rumicis'' feeds on maize, strawberries and other herbaceous plants. The moth's evolution has been affected by the industrial melanism that occurred in Europe during the late 19th and early 20th centuries, causing a dramatic increase in two aberrations (''salicin'' and ''lugubris''), which have darker grey wings. Today, ''A. rumicis'' is important to conservation efforts in the United Kingdom, because, like many other species, it is in decline. However, as ...
