Most species of Spilanthes have been transferred to Acmella, A. calva typically has discoid heads but radiate heads are also known. A. uliginosa looks very similar in leaves and heads but has tetramerous flowers. Pl. check this if you have close up of head.
Achenes are very important for this genus.
