(<i>Polygonaceae</i>). Het is een plant die te vinden is tussen het gras, op stenige bodem en op <a href="/wiki/Moeras" title="Moeras">moerasgrond</a>. De plant komt van nature voor in het <a href="/wiki/Arctisch_gebied" class="mw-redirect" title="Arctisch gebied">arctisch gebied</a> en naar het zuiden toe in de <a href="/wiki/Alpen" title="Alpen">Alpen</a>, <a href="/wiki/Karpaten" title="Karpaten">Karpaten</a>, <a href="/wiki/Pyrenee%C3%ABn" title="Pyreneeën">Pyreneeën</a>, <a href="/wiki/Kaukasus_(gebergte)" title="Kaukasus (gebergte)">Kaukasus</a> en het <a href="/wiki/Tibetaans_Hoogland" title="Tibetaans Hoogland">Tibetaans Hoogland</a> op een hoogte van 1000 tot 3000 m. </p><p>De plant wordt 5–25 cm hoog, vormt een <a href="/wiki/Wortelstok" title="Wortelstok">wortelstok</a> en heeft een onvertakte <a href="/wiki/Stengel" title="Stengel">stengel</a>. De <a href="/wiki/Bladvorm" title="Bladvorm">lancetvormige</a> <a href="/wiki/Blad" title="Blad">bladeren</a> zijn 2–8 cm lang. Langs de stengel worden in de oksels van de bladschubben <a href="/wiki/Broedbol" title="Broedbol">broedbolletjes</a> gevormd, waaraan de plant de <a href="/wiki/Soortaanduiding" title="Soortaanduiding">soortaanduiding</a> <i>viviparum</i> te danken heeft. De plant vermeerdert zich hoofdzakelijk door deze broedbolletjes. De broedbolletjes worden door <a href="/wiki/Alpensneeuwhoen" title="Alpensneeuwhoen">alpensneeuwhoenders</a> gegeten. </p><p>De plant bloeit van mei tot augustus met 3–4 mm lange, witte tot rozerode <a href="/wiki/Bloem_(plant)" title="Bloem (plant)">bloemen</a>, die in een <a href="/wiki/Aar_(bloeiwijze)" title="Aar (bloeiwijze)">aar</a> staan. </p><p>De vrucht is een <a href="/wiki/Dopvrucht" title="Dopvrucht">dopvrucht</a>.
