Alexgeorgea is a genus of three plant species found in Western Australia belonging to the family Restionaceae named in honour of the botanist Alex George in 1976.

[2] The genus Alexgeorgea was first discovered by Sherwin Carlquist on 2 September 1974 when he found a population of A. subterranea on the Cockleshell Gully road north of Jurien Bay in Western Australia.

At first, Carlquist, an American botanist and professor at Claremont Graduate University doing field work in Western Australia, could only locate male plants of what he immediately identified as a restionaceous species.

In his original description of the new genus in a 1976 volume of the Australian Journal of Botany, Carlquist notes his discovery may have not occurred if he had not seen the female flowers at anthesis due to the short-lived nature of the thread-like styles.

Johnson examined the herbarium specimens labeled as R. nitens and discovered that the alleged above ground fruits were actually malformations possibly resulting from smut fungus.
