replaced synonym: Zygophyllum glaucum F.Muell. legitimate

• Text: "ZYGOPHYLLUM GLAUCUM - p. 102. The specific name of this plant is to be altered in Z. glaucescens since Prof. E. Meyer pre-employed the above name for a South African species (conf. Flora, Botanische Zeitung, 1843; Harvey & Sonder, Flora Capensis, i. 362)."
• Comment: As Mueller states, E. Meyer (Flora 26: 230 (1843)) had previously published the name Zygophyllum glaucum in a list of South African species but did not provide a description for it. The name was validated by W.H.Harvey & O.W.Sonder, Fl. Cap. 1: 362 (1860), but this post-dates Mueller's 1855 publication of Z. glaucum for an Australian taxon. Mueller's publication of Z. glaucescens as a replacement name is thus superfluous.
• Comment: The name “Zygophyllum glaucescens F.Muell. var. glaucescens” is listed by A.D.Chapman, Austral. Pl. Name Index 3030 (1991), but since the species name is illegitimate this autonym is not established, in accordance with ICN Art. 27.2 (Melbourne Code, 2012).
