nfoto Posted February 4, 2013 Share Posted February 4, 2013 Rørslett, B. 2013. Gagea lutea (L.)Ker Gawl. (Liliaceae). Yellow Star-of-Bethlehem. Flowers photographed in visible and ultraviolet light. http://www.ultraviol...r-of-bethlehem/ Gagea lutea (L.)Ker Gawl.NO: GullstjerneSE: VårlökDK: Almindelig Guldstjerne FI: IsokäenrieskaDE: Wald-Goldstern EN: Yellow Star-of-Bethlehem This small spring species has a wide European distribution, and thrives on rich soils in parks, meadows, and open decidious forests. The foliage withers rapidly after seedset and the plant persists by means of its subterranean tubers until the next spring arrives. The flowers have petals green on the outer side, and the inside is yellow with a greenish tinge to it. G. lutea is among the first flowers to appear in spring, and the plants are eagerly visited by bees and other pollinators. Plants photographed near Oslo, Norway, 5 Apr 2007. Image reference: GAGE_LUT_I0704054024_VIS.jpgVisible light. Nikon D200, UV-Nikkor 105 mm f/4.5, Baader UV/IR Cut filter. Image reference: GAGE_LUT_I0704054018_UV.jpgUltraviolet light. Nikon D200, UV-Nikkor 105 mm f/4.5, Baader U 2" (Venus) filter, SB-140 flash. The UV marks on the basal part of the petals are prominent and show a similar two-pronged appearance to those of the closely related G. pratensis, but are slightly smaller and less acutely shaped.
