Tecticornia indefessa (Chenopodiaceae: Salicornioideae), a new mat samphire (formerly Tegicornia) from north of Esperance, Western Australia
SHEPHERD, K.A.

A taxon previously thought to be an intergeneric hybrid between an unknown species of the former genus 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 distinct species: Tecticornia indefessa K.A.Sheph. While sharing a similar mat-like habit and perianth structure to the dioecious T. uniflora, this taxon has bisexual or female flowers with distinctive seeds. Previous analysis of nuclear DNA sequences supports this taxon as distinct. Illustrations and maps and a revised description of T. uniflora are included.
