''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 and was named in honour of William Anderson, the surgeon and naturalist who sailed with James Cook.〔Lowrie, A. and Kenneally, K.F. (1999). ''Stylidium candelabrum'' (Stylidiaceae), a new species from the Northern Territory, Australia. ''Nuytsia'', 13(1): 251-254.〕 ==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.〕 In 2010, Sachin A. Punekar and P. Lakshminarasimhan published the new species ''S. darwinii'' from Western Ghats of Karnataka, India. They placed it in subgenus ''Andersonia'' and mentioned it was closely allied with ''S. kunthii'', ''S. inconspicuum'', and ''S. tenellum'', but they did not place it within a section.〔Punekar, S.A., and P. Lakshminarasimhan. (2010). (''Stylidium darwinii'' (Stylidiaceae), a new trigger plant from Western Ghats of Karnataka, India. ) ''Journal of the Botanical Research Institute of Texas'' 4(1): 69-73.〕 Also in 2010, botanist A. R. Bean described three new Australian species from the Northern Territory (''S. exiguum'', ''S. notabile'', and ''S. osculum'') that belong to subgenus ''Andersonia'', but he did not place them within a section.〔Bean, A. R. 2010. Four new species of ''Stylidium'' Sw. (Stylidiaceae) from northern Australia. ''Austrobaileya'', 8(2): 107-117.〕
