Nico Posted June 23, 2013 Share Posted June 23, 2013 Chalwatzis, N. 2013. Genista tinctoria L. (Fabaceae). Dyer’s Broom. Flowers photographed in visible and ultraviolet light. Genista tinctoria L.DE: Färber-Ginster EN: Dyer’s Broom This plant is a small shrub, usually less than one meter high. The entire plant is toxic. As the name suggest, it has been used to extract a yellow dye. Modifications with different metal ions can lead to other colours (green, brown). Flowers were photographed near Bensheim, Germany 14 June 2013. Images were taken with a broadband-modified Panasonic Lumix G1 and the EL-Nikkor 80mm/f5.6 at f11. Visible light image with Baader UV/IR cut filter at ISO 100image reference: NCH_P1090356_130614 UV-image, Baader U-filter 2”, ISO 400, sunlightimage reference: NCH_P1090357_130614 The banner appears UV-bright with dark veins, while the keel and the wings are mostly UV-dark.Since in some Fabaceae species like G. tinctoria different parts of the petals become visible at different times it seems worthwhile to capture flowers in different stages, if possible.
