Coming to Grips with Wobbly Flowers

Coming to grips with wobbly flowers reported in ScienceDaily 29 May 2012 and Functional Ecology, Vol. 26, pages 941–947, August 2012. Many flower petals have cone shaped cells on the surface of their petals.  For flowers odd shape, such as snapdragons, this enables bees to grip the surface without falling off.  However, many flowers that have a […]
