There seems to be two versions of this name going - Eryngium billardieri Delile
Eryngium billardierei F.Delaroche and the website has used both inconsistently (search for 'billardier') at https://efloraofindia.com/efi/eryngium/ https://efloraofindia.com/efi/eryngium-billardieri/ I presume this may have arisen by expanding an ambiguous author abbreviation "Del."; the form according to PoWo (https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:841675-1), flora.org.il (https://flora.org.il/en/plants/erybil/), and others is Eryngium billardierei F.Delaroche All the best, David -- You received this message because you are subscribed to the Google Groups "eFloraofIndia" group.
