does it look like any of these? http://images.google.com/images?sou...GGLG:2006-24,GGLG:en&q=spilanthes&sa=N&tab=wi If so then it is known as peek-a-boo flower or toothache plant. in the asteraceae genus spilanthes
The plant is Anacyclus pyrethrum & not Spilanthus. Spilanthus too is from the same family. They differ in looks.
Apologies, but your photograph of Anacyclus pyrethrum looks nothing like any other image of Anacyclus pyrethrum on a Google Image Search.
Mislabeled photos appear on web pages, pictures of plants that look like something that a name is being sought for should be checked against other pictures and also written descriptions before that name is adopted. Note that some genera have species that are differentiated by details that may not be apparent in ordinary photos.
