Stylidium subg. Tolypangium

Despectae Debilia Echinospermum Floodia Guttatae Junceae Lanata Lineares Repentes Saxifragoidea Sparsifoliae Squamosae Verticillatae Tolypangium is a subgenus of the genus Stylidium that is characterized by ovoid to longish capsules.

This subgenus was part of the earliest taxonomic division among the triggerplants (genus Stylidium).

Subsequent authors generally followed this classification, which is based almost entirely on the features of the capsule.

[1] Recent genetic analysis, combined with an exhaustive morphological comparison, has revealed that the classification defined by Johannes Mildbraed in 1908 is not the most accurate description of how the members of different subgenera and sections are related.

[2][3] As part of the Flora of Australia series, Juliet Wege will be reviewing and updating the taxonomy of the Stylidiaceae.
