    The calyx of a Hermannia cuneifolia flower is about fully grown when the tip of the corolla appears. The bell-shaped calyx is rough-surfaced from small protuberances on its fleshy surface. The calyx has five pointed lobes and longitudinal ridges from its base to the tips and sinuses of the lobes.

    The open yellow flower has lifted its normally pendulous body for a camera glimpse inside, where the anthers and style wait for pollinators to enter, rather than meeting them in the open.

    The old flower, no longer flaring widely, has turned orange and may sometimes be red before the petals disappear (Vlok and Schutte-Vlok, 2015; Le Roux, et al, 2005; Bond and Goldblatt, 1984; JSTOR; iNaturalist).
