I be cautious of species indentification base solely on leaf structure, while I dont doubt the skills of the people doing the work nor that they arent being meticulious but any botanist will tell you that species identification relies on multiple factors including plant structure, flowering details etc as an exampe just look at the 350+ species of grevillea <http://en.wikipedia.org/wiki/Grevillea> I'd be very adverse to using such a tool for identification of species in an encyclopeadic context. It may be work for genus level but even there we'd be finding false positives. > > I'm looking forward to seeing people solve more problems like this. > > _______________________________________________ > Commons-l mailing list > [email protected] > https://lists.wikimedia.org/mailman/listinfo/commons-l > -- GN.
