msubees Posted July 21, 2014 Share Posted July 21, 2014 Huang, Z.Y. (2014) Trifolium repens L. (Fabaceae) White Clover. Flowers photographed in ultraviolet and visible light. http://www.ultraviol...ns-white-clover Synonyms:Trifolium repens var. giganteum Lagr.-Foss.Trifolium repens var. repens L.Trifolium repens var. biasolettii (Steud. & Hochst.) Asch. & GraebTrifolium occidentale CoombeOther Common Name:Dutch cloverWhite Dutch cloverComment:White clover grows almost everywhere and is an important honey plant for honey bees in Michigan. Photographs taken at Michigan State University Bee Biology Building -- I had a StateNews interview on that day. It was just after rain so the clover inflorescence had many water drops, these became much more profound under UV. UV signature of this flower is similar to other legumes with mostly black and some bluish false color. Reference:1. Wikipedia (21 July 2014) Trifolium repens. Wikimedia Foundation, San Francisco, CA.
