What are are commonly known as milkworts or snakeroots, Nothofagus or Polygala ?
Nothofagus Nothofagus, also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America (Chile, Argentina) and Australasia (east and southeast Australia, New Zealand, New Guinea and New Caledonia). The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules and pollen, with fossils extending into the late Cretaceous and occurring in Australia, New Zealand, Antarctica and South America. In the past, they were included in the family Fagaceae, but genetic tests revealed them to be genetically distinct, and they are now included in their own family, the Nothofagaceae (literally meaning "false beeches" or "bastard beeches").
Glyceria maxima Glyceria maxima (Hartm.) Holmb. (syn. "G. aquatica" (L.) Wahlenb.; "G. spectabilis" Mert. & W.D.J. Koch; "Molinia maxima" Hartm.; "Poa aquatica" L.), commonly known as Great Manna Grass, Reed Mannagrass, and Reed Sweet-grass, is a species of rhizomatous perennial grasses in the mannagrass genus native to Europe and Western Siberia and growing in wet areas such as riverbanks and ponds. It is highly competitive and invasive and is often considered to be a noxious weed outside its native range.
