'''''Andersonia''''' is a [[subgenus]] of ''[[Stylidium]]'' that is characterized by a linear [[hypanthium]], recurved mature [[capsule (fruit)|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 (naturalist)|William Anderson]], the surgeon and naturalist who sailed with [[James Cook]].<ref>Lowrie, A. and Kenneally, K.F. (1999). ''Stylidium candelabrum'' (Stylidiaceae), a new species from the Northern Territory, Australia. ''Nuytsia'', 13(1): 251-254.</ref>

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

In 2010, [[Sachin Anil Punekar|Sachin A. Punekar]] and P. Lakshminarasimhan published the new species ''[[Stylidium darwinii|S.&nbsp;darwinii]]'' from [[Western Ghats]] of [[Karnataka]], India. They placed it in subgenus ''Andersonia'' and mentioned it was closely allied with ''[[Stylidium kunthii|S.&nbsp;kunthii]]'', ''[[Stylidium inconspicuum|S.&nbsp;inconspicuum]]'', and ''[[Stylidium tenellum|S.&nbsp;tenellum]]'', but they did not place it within a section.<ref name="Punekar 2010">Punekar, S.A., and P.
