Shepherd, K.A., Tecticornia indefessa (Chenopodiaceae: Salicornioideae), a new mat samphire(formerly Tegicornia) from north of Esperance, Western Australia. Nuytsia 17: 367–374 (2007). Ataxon previously thought to be an intergeneric hybrid between an unknown species of the formergenus Halosarcia Paul G.Wilson (now Tecticornia Hook.f.) and Tegicornia uniflora Paul G.Wilson(now Tecticornia uniflora (Paul G.Wilson) K.A.Sheph. & Paul G.Wilson) is recognised as a distinctspecies: Tecticornia indefessa K.A.Sheph. While sharing a similar mat-like habit and perianth structureto the dioecious T. uniflora, this taxon has bisexual or female flowers with distinctive seeds. Previousanalysis of nuclear DNA sequences supports this taxon as distinct. Illustrations and maps and a reviseddescription of T. uniflora are included.
