Sign in to savePrionium serratum, the palmiet, is a robust, evergreen, semiaquatic, rhizomatous flowering plant growing to in height. It is the only species in the genus Prionium, and is endemic to South Africa (Cape Province and KwaZulu-Natal). Some authors have separated Prionium from the Thurniaceae, putting it instead in its own family, the Prioniaceae.

Palmiet (Prionium serratum E.Mey. syn. Juncus serratus L.f., Acorus palmita Licht., Prionium palmita E.Mey.) is een robuuste, semiaquatische, bloeiende plant met wortelstokken die zo'n 2 m hoog kan worden. De naam palmiet is ingevoerd door Jan van Riebeeck als Wilde palmit. Het is de enige soort in het geslacht Prionium en is endemisch in Zuid-Afrika van de West-Kaap tot in KwaZulu-Natal.[1] Er zijn auteurs die de soort niet in de Thurniaceae plaatsen, maar er zijn eigen familie aan toekennen de Prioniaceae.[2] Op de Zuid-Afrikaanse Rode Lijst komt de plant voor als afnemend met name omdat hij in KwaZulu-Natal voor de traditionele heelkunde geoogst wordt en het drasland waarin hij voorkomt door overbegrazing bedreigd wordt. SANBI plaatst de plant in de Juncaceae.[3] Inhoud 1 Beschrijving 2 Taxonomie en verspreiding 3 Galerij 4 Externe links Beschrijving De stam van de plant kan tot 100 mm in doorsnede worden en is bedekt met de zwarte, vezelige basis van oude bladeren, spiraalsgewijs geplaatst op een wijze die nauw overeenkomt met de verwante familie Juncaceae.

Prionium serratum, the palmiet, is a robust, evergreen, semiaquatic, rhizomatous flowering plant growing to in height. It is the only species in the genus Prionium, and is endemic to South Africa (Cape Province and KwaZulu-Natal). Some authors have separated Prionium from the Thurniaceae, putting it instead in its own family, the Prioniaceae.
==Description== The stem of P. serratum is up to in diameter and covered with the black, fibrous bases of old spirally arranged leaves, four-ranked or tristichous, as in the closely related family Juncaceae, a family in which it was previously placed - it also has close affinities with the bergpalmiet (Tetraria thermalis) in the Cyperaceae. The strap-like lanceolate leaves are rigid, with a high silica content, narrow, leathery, grey-green, and with toothed margins. The small, brown flowers are on a branched inflorescence about 1 m in length. Plants are hermaphroditic and pollination is anemophilous. The fruit is a dry dehiscent triangular capsule, with three seed chambers and arillate seeds which are hispid (with sclerenchymatous fibres) and winged. The net-like, black fibrous, reticulate leaf sheaths are often found on beaches near rivers with colonies of palmiet (see Gallery). New flower shoots are cooked as vegetables.
