Abstract
New chromosome counts suggest that the former Leucanthemum vulgare var. esterellense Briq. & Cavill. deserves acknowledgement as an independent species. The new combination L. esterellense (Briq. & Cavill) Vogt, Konowalik & Oberpr., proposed here, denotes a marguerite species endemic to the Massif de l'Esterel (S France) with an octoploid chromosome number of 2n = 72. It is also demonstrated that recently formed hybrids between L. glaucophyllum and L. pallens at Mt Bignone (Liguria, NW Italy) exhibit hepta- and octoploid chromosome numbers. These hybrids are described as L. ×marchii Konowalik, Vogt & Oberpr., a nothospecies new to science. Additionally, the names L. subglaucum de Laramb., L. vulgare var. esterellense Briq. & Cavill. and L. vulgare subsp. glaucophyllum Briq. & Cavill. are lectotypified and new chromosome counts for all presently surveyed Leucanthemum taxa are provided.Citation: Karyological analysis reveals two new polyploid marguerite taxa (Leucanthemum, Compositae–Anthemideae) in S France and NW Italy. – Willdenowia 48: 221–226. doi: https://doi.org/10.3372/wi.48.48204Version of record first published online on 3 August 2018 ahead of inclusion in August 2018 issue.
