Andrea B. Posted February 19, 2013 Share Posted February 19, 2013 Blum, A.G. (2013) Brassica nigra (L.) W.D.J. Koch (Brassicaceae) Black Mustard. Flowers photographed in ultraviolet and visible light. http://www.ultravioletphotography.com/content/index.php/topic/121-brassica-nigra-black-mustard/ Seal Cove, Mount Desert Island, Maine, USA 17 July 2012 Wildflower Synonyms: Sinapis nigra L. Comment: Like many mustards, B. nigra shows UV-dark veining and a dark blotch at the petal base. The fruits are on erect pedicels which distinguishes Black Mustard from the similar B. juncea.
