Alsinoida Andersonia Biloba Tenella Uniflora 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.

[1] In his 1908 monograph, Johannes Mildbraed had treated subgenus Andersonia as a rank without sections.

[2] In 2010, Sachin A. Punekar and P. Lakshminarasimhan published the new species S. darwinii from Western Ghats of Karnataka, India.

[3] 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.
