Schoenus calcatus is a species of Cyperaceae endemic to Western Australia. [1]
S. calcatus is a small cushion-forming perennial. The learves are spirally arranged and have both a short blade and a short sheath. [2]
Schoenus calcatus was first described in 1997 by Karen Wilson. [3] [2] There are no synonyms. [1] The specific epithet. calcatus, is derived from the Latin verb, calcare, "to tread upon" or "walk over" and refers to a potential threat to the species. [2]
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus Carex with over 2,000 species.
Schoenus is a predominately austral genus of sedges, commonly known as bogrushes, or veldrushes in South Africa. Species of this genus occur mainly in South Africa, Australia and Southeast Asia. Others are found in scattered locations worldwide, from Europe to Asia, North Africa and the Americas. Three species occur in the peatlands of southern South America, including S. antarcticus which is found in Tierra del Fuego, where it forms a component of hyperhumid Magellanic moorland.
