Two taxa are represented among the material cited by Candolle under Wollastonia montana. That representing Blume’s concept of Verbesina montana certainly does not belong to Melanthera, and it is felt better to include it here within the concept of Wollastonia. It should also be noted that Wedelia wallichii var. megalantha is not conspecific with type material of W. wallichii but appears to be Wollastonia biflora.
