The Tylecodon grandiflorus flower is tubular, long, narrow and curved up. There is a short, five-lobed calyx around the flower base, its lobes pale, faintly hairy and acutely pointed.
The five oblong to slightly obovate corolla lobes have mucronate tips and ciliate margins. They spread and later recurve. The flower mouth is usually turned up. The flower segments are orange-red or red, in picture not particularly brightly. The small, dark anthers are exserted (Smith, et al, 2017; Van Jaarsveld, et al, 2006; Manning and Goldblatt, 1996; iNaturalist).
