The spreading Tritonia bakeri subsp. lilacina tepals are unevenly obovate, attenuating to indifferently pointed tips. Three longitudinal vein lines from base to tip are flanked by numerous lateral ones, ascending and branching in roughly similar ways on different tepals.
Colouring appears slightly deeper pink on the outer three tepals. It is variable to nearly white on some plants. A short, sometimes purple-pointed, yellowish stripe at the base of each tepal forms a six-pointed star in the perianth base.
Three blue-black, oblong anthers, roundly curved, appear in charge over the flower centre. The about as tall, three-branched style is too pale to be dominant, although it is very likely to be functional during insect visits (Vlok and Schutte-Vlok, 2015; Moriarty, 1997; iNaturalist; https://www.pacificbulbsociety.org).
