Abstract

Recent molecular and morphological studies have shown that the genera Halosarcia, Pachycornia, Sclerostegia, Tecticornia and Tegicornia are closely related and form a monophyletic group. Support for the monophyly of the individual genera in the group is lacking, with the smaller genera nested in a paraphyletic Halosarcia. In light of this it is proposed that these genera be subsumed into a single genus for which the most appropriate available name is Tecticornia. A conspectus is provided of all species in the expanded Tecticornia, with new combinations given for 30 species and 13 subspecies.

Appendix 1.  Data matrix for morphological characters numbered as in Table 6 (in Shepherd et al. 2005b)
Polymorphic states are represented as the following: a = 0/1, b = 0/2, c = 1/2, d = 2/4, e = 3/5, f = 2/3; Collectors: KS = K.A. Shepherd; PGW = Paul G. Wilson; ASG = Alex S. George; IC = Ian Clarke; JGC = J. Gibbs-Clema; HP = Hugh Pringle; DJE = D.J. Edinger; RJC = Ray J. Cranfield; PKL = P.K. Latz; BPK = B.P. Koustaal; BD = Bernard Dudley; EST = Michelle Waycott; Herbaria: US = Smithsonian Institution, BC = Institut Botánic de Barcelona, MEL = Royal Botanic Gardens Melbourne. This appendix replaces Table 6 in Shepherd et al. (2005b) as columns 52 onwards are in erratum. This does not affect the results of the morphological phylogenetic analysis therein.
