"Andersonia" is a subgenus of "Stylidium" that is characterized by a linear hypanthium, recurved mature capsule walls, an erect and persistent septum, and many seeds. This subgenus occurs in areas of tropical northern Australia and into Southeast Asia. [Lowrie, A. and Kenneally, K.F. (1999).

Taxonomy

In his 1908 monograph, Johannes Mildbraed had treated subgenus "Andersonia" as a rank without sections. He also had established the subgenus "Alsinoides" for species related to "S. alsinoides", which are morphologically similar to species of subgenus "Andersonia". In 2000, A.R. Bean published a taxonomic revision of subgenus "Andersonia" and reduced subgenus "Alsinoides" to sectional rank, renamed "Alsinoida". Bean also established three other new sections based on cladistic analysis: "Biloba", "Uniflora", and "Tenella", which is really just George Bentham's series "Tenellae", though heavily revised. By adding sectional ranks to subgenus "Andersonia", Bean also established the autonym section "Andersonia".Bean, A.R. (2000). A revision of "Stylidium" subg. "Andersonia" (R.Br. ex G.Don) Mildbr. (Stylidiaceae). "Austrobaileya" 5(4): 589-649.]
