Summary Vogt, R. & Oberprieler,C.: Mauranthemum,a new name for LeucoglossumB. H. Wilcox & al. non S. Imai (Compositae,Anthemideae). - Taxon 44: 377-378. 1995. - ISSN 0040-0262. Mauranthemumis publishedas an avowed substitutefor LeucoglossumB. H. Wilcox & al. 1993, which is an illegitimatelater homonymof LeucoglossumS. Imai 1942. New combinationsfor four species and one subspeciesare proposed.

The Leucoglossum B. H. Wilcox & al. was recenty established in Bremer & Humphries (1993: 142) to include the annual species formerly placed in Leucanthe- mum sect. Eunuchoglossum DC. (Vogt, 1991). Unfortunately it is an illegitimate later homonym of Leucoglossum S. Imai (1942: 524), a name that is currently in use for a genus of the ascomycete family Geoglossaceae (Greuter & al., 1993; Eriksson & Hawksworth, 1993). We are currently revising the genus. The following new generic name and new combinations are presented here to prevent spreading use of the illegitimate name. Mauranthemum Vogt & Oberprieler,nom. nov. = Leucoglossum B. H. Wilcox & al. in Bull. Nat. Hist. Mus., Ser. Bot. 23: 142. 1993 (non S. Imai in Bot. Mag. (Tokyo) 56: 524. 1942. - Type: Mauranthemumpaludosum (Poir.)
