Isoetes beestonii

Isoetes beestonii is a species of isoetalan plant from the latest Permian of New South Wales and Queensland.

[3] Isoetes beestonii is preserved as whole plants in life position within bedding planes, and presumably lived as an early successional weed in lake and pond sedimentary environments, like living Isoetes.

I. beestonii is thought to have grown in monospecific assemblages around and within oligotrophic ponds and lakes.

Wood et al. (2020) regarded the relationship between pre-Jurassic isoetalean species and modern Isoetes with uncertainty.
