Species description (© Flora Helvetica 2018)

30-100 cm hoch, meist verzweigt. Grundständige Blätter pfeilförmig, mit spitzen, abwärts gerichteten Ecken, etwas dicklich, mit undeutlichen Nerven, 2-5mal so lang wie breit, untere gestielt, obere sitzend. Seitenäste des Gesamtblütenstandes unverzweigt oder nur die untersten wenig verzweigt. Blüten rot bis grün, meist eingeschlechtig. Äussere Perigonblätter zur Fruchtzeit zurückgeschlagen, innere rundlich, ganzrandig, 3-5 mm lang, mit kleiner, rückwärts gerichteter Schwiele.
