Gladiolus orchidiflorus bracts

The two bracts subtending each Gladiolus orchidiflorus flower are greenish, sometimes purplish grey. The outer bract becomes about 2 cm long with margins rolled in, the inner one sometimes slightly shorter, its tip notched. The pointy bracts are conspicuous over the flowers in picture (Goldblatt and Manning, 1998; Vlok and Schutte-Vlok, 2015; Le Roux, et al, 2005; iNaturalist).
