Species description (Flora Helvetica 2018)

Ähnlich wie O. stricta, aber Ausläufer meist fehlend, vom Grund an ästig, Stängelhaare meist ungegliedert (1zellig), Nebenblätter meist vorhanden. Stiel des Blütenstandes am Grund ohne knotiges Gelenk. Kronblätter (6-)10-13 mm lang. Fruchtstiele deutlich zurückgeschlagen. Kapsel 15-25 mm lang, dicht mit kurzen, abwärtsgerichteten Haaren besetzt (dadurch fast grau), und oft zusätzlich mit längeren abstehenden Haaren.
