Species description (Flora Helvetica 2018)

Stängel 15-30 cm hoch, geflügelt, mit 1-4 endständigen, von einer Spatha umschlossenen Blüten. Blätter grundständig, schmal-lineal, steif aufrecht, 2-3 mm breit. Blüten hellblau bis violettblau, mit gelbem Schlund, Durchmesser 1-2 cm. Perigonblätter 6, die inneren wenig schmäler als die äusseren, frei oder am Grund verwachsen, verkehrt-eiförmig, mit aufgesetzter Spitze. Staubblätter 3, miteinander verwachsen und die Narben umschliessend. Frucht eine 3fächerige, mehrsamige Kapsel.
