es. Various species of ''Phalaris'' grow on every continent except Antarctica. They can be found in a broad range of habitats from below sea level to thousands of feet above sea level and from wet marshy areas to dry places. ''P. arundinacea'' and ''P. aquatica'' are sometimes invasive species in wetlands.

Alkaloids

Some ''Phalaris'' species contain

gramine Gramine (also called donaxine) is a naturally occurring indole alkaloid present in several plant species. Gramine may play a defensive role in these plants, since it is toxic to many organisms. Occurrence Gramine has been found in the giant reed, ...

'', and '' Phalaris brachystachys'' are known to contain the alkaloids DMT, 5-MeO-DMT, and 5-OH-DMT (bufotenin). Some research has been done into the variability of alkaloids in the ''Phalaris'' grasses. Strains with high levels of alkaloids are best avoided in locations with grazing cattle and sheep, due to potential toxicity. Such high-alkaloid strains include ''Phalaris aquatica AQ-1'' and the species ''P. brachystachys''. Seasonal and weather patterns also appear to affect alkaloid concentration, as most toxicity occurs in autumn and in times of drought. Regrowth after grazing or mowing also shows a considerable increase in alkaloids. In June 2018, mobs of wild
