Taxonomy
Section Thelocalyx was first described by Jules Émile Planchon in 1848 and was later moved to the rank of subgenus in 1891 by Carl Georg Oscar Drude. It was later moved back to sectional rank by Rüdiger Seine and Wilhelm Barthlott in 1994.[2] In 1996, Jan Schlauer revised the infrageneric taxonomy and supported the subgeneric rank, citing the pentamerous gynoecium and suggesting that the two species are relatively primitive with respect to other species in the genus.[3] However, molecular phylogenetic analysis by Rivadavia, Kondo, Kato and Mitsuyasu in 2003 supported returning it to section rank within subgenus Drosera.[4]
