The Brunsvigia bosmaniae perianths in this umbel are dark on the outside, dull pinkish red while pale to white within, apart from the dark central stripe, longitudinally down every segment or tepal.
The funnel-shape of the perianths or individual flowers is typical, so is the final outward curve of the rounded tepal tips.
The pedicels and ovaries of the flowers in picture are a dark brownish purple, adding to the colour contrast with the corolla insides (Duncan, et al, 2016; Manning, 2007; iNaturalist).
