Taxonomic notes: It is possible that the MU and/or SL region collections belong to the closely related (perhaps even not separable as treated by A. Prescott & J. Venning, 1983) Trianthema australis Melville, Kew Bull. 7:266 (1952), which may occur in N.S.W., or to T. pentandra L., Mant. 1:70 (1767), which is native to Africa and the Middle East. Melville (1952) separated these species as follows: Top of operculum prolonged into sharp lateral ridges bearing 2-5 teeth, sides almost straight but near the base often running out into an angular or somewhat rounded step or shelf. = Zaleya galericulata; Operculum bonnet-shaped with the crest on the top poorly developed and the base often everted, sides with distinct reticulate ridging = Trianthema australis; Operculum smooth, uniformly papillose, with blunt rounded crest and the base generally expanded into a rounded solid rim = Trianthema pentandra.
