The pygmy sundews (Drosera section Bryastrum) are the second-largest group of Australian Drosera in terms of species number following the tuberous sundews. According to the latest revisions (Fleischmann et al. 2018; Robinson et al. 2018) they currently comprise 51 species in southwest Western Australia and six named natural hybrids (Lowrie 2014; Lowrie et al. 2017). Within the pygmy Drosera, a wide range of flower colors can be found, ranging from pure white, various shades of pink, metallic orange, and red to yellow colors, quite often with bi- or rarely even tricolored petals (Lowrie 1989; Robinson et al. 2018). The color combination of lime yellow petals with white base has thus far been considered to be unique to D. citrina (Lowrie & Carlquist 1992; Lowrie 2014; Lowrie et al. 2017).
