Species description (Flora Helvetica 2018)
Ähnlich wie Oe. biennis, aber Blätter 5-10mal so lang wie breit (bei Oe. biennis nur 3-6mal), Blütenstand vor dem Aufblühen nickend oder aufrecht, Kronblätter 0,5-1,5 cm lang, kürzer bis wenig länger als die Staubblätter. Fadenförmige Spitzen der Kelchblätter (im Knospenstadium) vom Grund an spreizend, nicht eng aneinander gedrückt.Flowering period (Flora Helvetica 2018)

Neue Rangstufe: Wechsel von Art zu Aggregat. Durch das Hinzukommen zusätzlicher Neophyten und der präziseren Fassung der Artengruppe ist die bisherige O. parviflora L. neu als Aggregat zu betrachten. Die Aufteilung der Gattung in Aggregate folgt dem taxonomischen Konzept von Dietrich («American School»), während sich die Definition der Arten an den Vorschlägen von Rostański orientiert («European School»).
