Hutchinson and Wettestein placed the family Cyperaceae in a separate monotypic order Cyperales and considered it to have been derived from the members of Juncales or Juncaceae on parallel line with Poaceae (Gramineae). Leaves are three-ranked or tristichous. The lodicules are situated above and opposite the superior palea or may be absent, or many (Ochlandra), or 2 … The Plant List includes 18,977 scientific plant names of species rank for the family Cyperaceae. Scirpus lacustris is used for matting. In Kobresia ovary is enclosed in a bract or utricle. The limits of these genera are also somewhat unsettled, with the circumscription and limits of such well-known genera as Cyperus and Scirpus (bulrushes or clubrushes) being somewhat controversial.
