Brown purple nutsedge ( Cyperus fuscus )

Zypergräser form a large genus from the family of the Sedge family ( Cyperaceae ), with over 600 species.


The Zypergräser are annuals or perennials. The stem is triangular or round. He is leafy at the base.

The total inflorescence is provided with foliage leaf-like bracts, and is composed of flat ears. The ears are sessile and tufted, or they are stalked and arranged spirrig. The individual spikelets are densely floriferous and have two lines standing, keeled bracts. Only with Cyperus michelianus the bracts are three lines. In all bracts sit flowers. The flowers are hermaphroditic: in the armpit of a carrier sheet to a three stamens and ovary with two or three scars.

The nut fruits are lenticular in zweinarbigen types, triangular in dreinarbigen.

The genus name Cyperus was already used by Pliny the Elder for the nutsedge. The name derives from the Greek kýperon what a water or meadow plant with aromatic root labeled ( Homer, Theophrastus, Herodotus ). Maybe it comes from kuparo - from Mycenaean, which is interpreted as Cyperus longus. A connection with Greek kypros Henna and Kyprion plantain, both of which are considered Semitic loanwords is discussed, but is uncertain.
