Bolboschoenus yagara is a species of flowering plant in the sedge family Cyperaceae. It is a perennial clonal herb, 0.8 to 1.3 meters tall, and develops underground rhizomes that terminate in spherical or ellipsoid tubers that are up to 3-4 centimeters in diameter. [1] It is able to propagate asexually through the tubers, as well as sexually by seeds. [2]
Bolboschoenus yagara is predominantly found in China and East Asia, with a fossilized specimen dated from the Late Pliocene period discovered in Shanxi, China. [3] Populations that were previously believed to be Bolboschoenus maritimus have been identified in Central Europe since 1996, with additional populations reported in Poland in 2006. The classification of Bolboschoenus yagara as a distinct species from Bolboschoenus maritimus was based on the morphology of the inflorescence, glumes, spikelets, and achenes. Bolboschoenus yagara has compound, or, rarely, head-like inflorescence with three to eight branches with two or three spikelets each. It has trifid styles, rufescent glumes, strong perianth branches that remain attached to mature achenes, and the achenes are nearly equilaterally trigonous. Bolboschoenus maritimus's inflorescences are head-like and have one to two branches. While its glumes are similar in color to Bolboschoenus yagara, almost all individuals of Bolboschoenus maritimus have bifid styles and digynous achenes.
It is possible that species that could not be clearly identified as either Bolboschoenus yagara or Bolboschoenus maritimus was in fact a B. yagara x B. maritimus hybrid. [4]
Bolboschoenus yagara is found in wetlands, swamps, and other wet habitats. Unlike B. maritimus, Bolboschoenus yagara is a glycophyte. [5] In experiments comparing the species to three other Bolboschoenus species (Bolboschoenus maritimus, Bolboschoenus laticarpus, and Bolboschoenus planiculmis), Bolboschoenus yagara was found to be the most sensitive to changes in nutrient supply and salt concentration, where increased concentrations caused a decrease in biomass, shoot number, fertility. In the dormant tuber stage, it is able to survive long-term high water levels. [6] Bolboschoenus yagara is able to survive in both mesotrophic and eutrophic conditions.
It is found in littoral habitats on mineral-poor grounds; in Europe its populations are concentrated in several pond basins in Central Europe, with limited frequency in other regions. As a result of this limited range, it is at risk in Europe because of intensive fish pond management. The range of Bolboschoenus yagara overlaps with that of Bolboschoenus planiculmis. [7]
Like Bolboschoenus planiculmis, Bolboschoenus yagara is an important part of the migratory habitat for the Siberian crane. In the Momoge National Nature Reserve in Jilin, an important stopover area for long-term refueling, along the East Asian–Australasian Flyway, Bolboschoenus yagara and other species of Bolboschoenus, in tandem with Phragmites communis , was the preferred plant community type for the cranes. [8]
Bolboschoenus yagara tubers, known as jing sanleng (Mandarin: 荊三稜), are used in traditional Chinese medicine to treat a number of ailments such as hyperemesis gravidarum, amenorrhea, and inflammatory-related conditions. [9] Previous studies have identified a number of metabolites from the tubers of Bolboschoenus yagara that are theorized to have anti-inflammatory, anti-oxidant, and other properties, although these claims are speculative and their effectiveness has not been demonstrated in humans.

Scirpus is a genus of grass-like species in the sedge family Cyperaceae many with the common names club-rush, wood club-rush or bulrush. They mostly inhabit wetlands and damp locations.
Rhynchospora alba, the white beak-sedge, is a plant in the sedge family, Cyperaceae. It is a tufted herbaceous perennial around 50 cm tall, with white inflorescences that flower in August. The fruit of the sedge is a small achene with a characteristic beak-like cap. It is dispersed by wind or falls by gravity, leading to individuals existing in tight clumps. The species favours wet, acidic and nutrient poor soils, thriving in Sphagnum-dominated bogs, but also peaty grasslands. As such it is often used as a positive indicator for bog and mire ecosystem health.
Fimbristylis miliacea, the grasslike fimbry or hoorahgrass, is a species of fimbry that probably originated in coastal tropical Asia but has since spread to most continents as an introduced species. It is a widespread weed in some areas and is sometimes problematic in rice paddies.
Bolboschoenus fluviatilis, the river bulrush, is a species of flowering plant in the sedge family, Cyperaceae. Its range includes Australia, New Zealand, New Caledonia, Canada, the United States, and northeastern Mexico. B. fluviatilis and its fruits are important as food sources for waterfowl such as geese, ducks, bitterns, and swans. It also provides cover and nesting sites for these and other species of birds, as well as small mammals. Like other Bolboschoenus species, B. fluviatilis has strong tubers and rhizomes which help to stabilize intertidal habitats by preventing erosion.
Bulbostylis capillaris is a species of sedge known by the common names densetuft hairsedge and threadleaf beakseed. It is native to much of North America, South America and the West Indies from Canada to Bolivia.
Bolboschoenus maritimus is a species of flowering plant from family Cyperaceae. Common names for this species include sea clubrush, cosmopolitan bulrush, alkali bulrush, saltmarsh bulrush, and bayonet grass. It is found in seaside wetland habitats over much of the world. It is widespread across much of temperate and subtropical Africa, Asia, Europe, North America, South America and various islands.
Schoenoplectus americanus is a species of flowering plant in the sedge family known by the common names chairmaker's bulrush and Olney's three-square bulrush. It is native to the Americas, where it is known from Alaska to Nova Scotia and all the way into southern South America; it is most common along the East and Gulf Coasts of the United States and in parts of the western states. It grows in many types of coastal and inland wetland habitat, as well as sagebrush, desert scrub, chaparral, and plains. This rhizomatous perennial herb easily exceeds two meters in height. The stiff stems are sharply three-angled and usually very concave between the edges. Each plant has three or fewer leaves which are short and narrow. The inflorescence is a small head of several spikelets which may be brown to bright orange, red, purplish, or pale and translucent. They have hairy edges. The fruit is a brown achene. The plant reproduces sexually by seed and colonies spread via vegetative reproduction, sprouting from the rhizomes.
Schoenoplectus heterochaetus is a species of flowering plant in the sedge family known by the common name slender bulrush. It is native to North America, where it can be found in scattered locations in Canada and the United States.
Schoenoplectiella mucronata is a species of flowering plant in the sedge family known by the common names bog bulrush, rough-seed bulrush, and ricefield bulrush. It is native to Eurasia, Africa and Australia. It grows in moist and wet terrestrial habitat, and in shallow water. It is a perennial herb growing from a short, hard rhizome. The erect, three-angled stems grow in dense clumps and can reach a metre tall. The leaves take the form of sheaths wrapped around the base of stem, but they generally do not have blades. The inflorescence is a headlike cluster of cone-shaped spikelets accompanied by an angled, stiff bract which may look like a continuation of the stem.
