It is present in Japan and far eastern Russia, and it has been introduced to many other regions of the world, including Europe, New Zealand, Hawaii, and Australia. It is a plant of wet areas in many types of habitat. This is a rhizomatous perennial herb forming clumps of stems 20 to 60 centimeters tall. The flat but curving leaves are mostly located at the base of the stems and are variable in length. The inflorescence is an array of many rounded clusters of many flowers each. Each flower has a number of dark brown to black tepals a few millimeters long and usually three small stamens enclosed between them. The fruit is an oblong capsule with a small beak on the tip.
Briza minor is a species of grass known by the common names lesser quaking-grass or little quakinggrass. It is native to the Mediterranean Basin, and it is known elsewhere, including much of North America, as an introduced species.

Carex buxbaumii is a species of sedge known as Buxbaum's sedge or club sedge. It is native to much of the northern Northern Hemisphere, from Alaska to Greenland to Eurasia, and including most of Canada and the United States. It grows in wet habitat, such as marshes and fens. This sedge grows in clumps from long rhizomes. The stems are 75–100 cm (30–39 in) in maximum height. The leaves are narrow and small. The inflorescence has a bract which is sometimes longer than the spikes. The fruits have dark-colored bracts and a sac called a perigynium or utricle which is gray-green and rough in texture.
Cynosurus echinatus is a species of grass known by the common names bristly dogstail grass, rough dog's-tail and hedgehog dogtail.

An herbicide-resistant strain can be found growing as a weed in canola and wheat fields in Chile. This is an annual grass growing 10 to 50 centimeters tall. The inflorescence is a rounded or oval cluster or series of clusters of spikelets. The fertile spikelet has an awn up to a centimeter long. The awns clumped closely together into a tuft gives the inflorescence its bristly, hairy appearance.
Erodium brachycarpum is a species of flowering plant in the geranium family known by the common names hairy-pitted stork's-bill and shortfruit stork's bill.

Polypogon monspeliensis, commonly known as annual beard-grass or annual rabbitsfoot grass, is a species of grass. It is native to the Old World, but it can be found today throughout the world as an introduced species and sometimes a noxious weed. It is an annual grass growing to heights between 5 centimeters and one meter. The soft, fluffy inflorescence is a dense, greenish, plumelike panicle, sometimes divided into lobes. The spikelets have long, thin, whitish awns, which give the inflorescence its texture.

This is a perennial herb producing a thin, branching stem easily exceeding a meter in maximum length. The submerged leaves are linear to widely lance-shaped and up to 15 by 4 centimetres in length and width, respectively, while the floating leaves achieve shorter maximum lengths and are ovate or elliptic. Both floating leaves and submerged leaves are borne on long petioles, a distinguishing characteristic. The inflorescence is a spike of many small flowers arising from the water on a peduncle.
Schismus barbatus is a species of grass known as common Mediterranean grass and kelch-grass. It is native to Eurasia, and it is also known as an introduced species in the southwestern United States. It grows in many habitats, including disturbed areas. It is an annual grass growing in small clumps. The stems grow up to 27 centimeters long and are lined with threadlike leaves.
