Checklist of the ultramafic flora of New Caledonia

Data from: How did the ultramafic soils shape the flora of the New Caledonian hotspot?

The file contains an updated list of the ultramafic flora of New Caledonia. The list was first compiled from the 25 volumes of the Flora of New Caledonia (Aubréville et al. 1967-) and records from the herbaria of New Caledonia (http://publish.plantnet-project.org/project/nou), the Muséum National d’Histoire Naturelle de Paris (P), and the Missouri Botanical, Gardens (MO). An extensive survey of recent literature, herbarium records and field observations was conducted to ensure the checklist was as complete as
possible. The recently revised checklist of the New Caledonian flora "FLORICAL"  Munzinger J, Morat P, Jaffré T, Gâteblé G, Pillon Y, Rouhan G, Bruy D, Veillon JM, Chalopin M. 2023. FLORICAL: Checklist of the vascular indigenous flora of New Caledonia. [accessed]. http://publish.plantnet-project.org/project/florical) was used to update the taxonomy.
To score the affinity of taxa to ultramafic soils, we used species description or occurrence localities. We assigned the category ultramafic-obligate (U) when habitat description or localities unambiguously states that a species is ultramafic- or serpentine-specialist. The category "ultramafic-facultative" (Uf) was assigned when adjectives such as "often", "sometimes", or "usually" were added to the description of species’ soil ecology, or when the taxa is known to occur (from locality) on different soil types.
