The genera Allocasuarina was created out of a grouping of plants formerly placed in Casuarina, because of subtle but consistent differences – Casuarina species have 6 to 20 scale-like teeth in each whorl of leaves, their samaras are grey or yellowish-brown, and the bracteoles of the fruiting cones are thin, woody and extend well beyond the ...

At one time, all species were placed in the genus Casuarina. Lawrence Alexander Sidney Johnson separated out many of those species and renamed them into the new genera of Gymnostoma in 1980 and 1982, [3] [4] Allocasuarina in 1982, [4] and Ceuthostoma in 1988, with some additional formal descriptions of new species in each other genus.
