Crassula pellucida flowering

The inflorescence of Crassula pellucida is a terminal fascicle comprising a single or small group of flowers. The flowers are white or pink-petalled with yellow centres, seen from spring to autumn.

C. pellucida is a variable plant as its five subspecies indicate. How many thousands of years will it take before there may be ten, or some split off as independent species? Or maybe the species does not exist at all anymore for the last botanist to investigate (Frandsen, 2017; Smith, et al, 1997; Bond and Goldblatt, 1984; iNaturalist).
