Schoenoplectiella hallii is a species of flowering plant in the sedge family [2] known by the common name Hall's bulrush. It is native to the United States, where it has a disjunct distribution, occurring in widely spaced locations throughout the Midwest and East. It is a rare plant. [1]

This rhizomatous annual, or sometimes perennial, [3] plant has stems which bend down or spread out instead of growing erect. They are up to 80 centimeters long, but often much shorter. The inflorescence contains a few spikelets which are up to 2 centimeters long by 2 to 3 millimeters wide. [4] Some flowers may also be produced on short stems that barely emerge from the leaf sheaths later in the season. [3]

This species grows in wet, sandy soils next to water bodies such as ponds and lakes. It is adapted to a habitat with fluctuating water levels. [5] This fluctuation prevents many other types of plants from moving into the area and competing with the sedge. [1]

Threats to this plant include anything that alters the hydrology of the habitat, for example, anything that prevents the fluctuating water levels and flooding that the plant requires. Other threats include loss of habitat to development or agriculture, livestock activity, off-road vehicle use, pollution, road maintenance, and habitat fragmentation. [3]

Taxonomy

This sedge was first described by Asa Gray in 1862 as Scirpus Hallii. [2] [6] Gray later (1867) described it as S. supinus var. Hallii. [7] In 1995, the American botanist, Stanley Galen Smith, transferred it to the genus, Schoenoplectus , [8] and Schoenoplectus hallii was the accepted name until it was transferred in 2003 to the genus, Schoenoplectiella , by Kåre Arnstein Lye.

<i>Schoenoplectus</i> Genus of plants

Schoenoplectus is a genus of plants in the sedges with a cosmopolitan distribution. Note that the name bulrush is also applied to species in the unrelated genus Typha as well as to other sedges. The genus Schoenoplectus was formerly considered part of Scirpus, but recent phylogenetic data shows that they are not closely related.

<i>Scirpus</i> Genus of flowering plants

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.

<i>Eleocharis</i> Genus of grass-like plants

Eleocharis is a virtually cosmopolitan genus of 250 or more species of flowering plants in the sedge family, Cyperaceae. The name is derived from the Greek words ἕλειος (heleios), meaning "marsh dweller," and χάρις (charis), meaning "grace." Members of the genus are known commonly as spikerushes or spikesedges. The genus has a geographically cosmopolitan distribution, with centers of diversity in the Amazon Rainforest and adjacent eastern slopes of the South American Andes, northern Australia, eastern North America, California, Southern Africa, and subtropical Asia. The vast majority of Eleocharis species grow in aquatic or mesic habitats from sea level to higher than 5,000 meters in elevation.

<i>Schoenoplectus californicus</i> Species of grass-like plant

Schoeneoplectus californicus is a species of sedge known by the common names California bulrush, southern bulrush and giant bulrush. It is also sometimes called "tule", but the closely related Schoenoplectus acutus is the species most often referred to by that name.

<i>Bolboschoenus fluviatilis</i> Species of flowering plant in the sedge family Cyperaceae

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.

<i>Scirpus cyperinus</i> Grass-like plant of wetlands

Scirpus cyperinus, commonly known as woolgrass, is an emergent wetland herb that is native to the eastern United States and eastern Canada. Other common names include cottongrass bulrush and brown woolly sedge.

<i>Schoenoplectus americanus</i> Species of grass-like plant

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.
