nfoto Posted April 28, 2013 Share Posted April 28, 2013 Rørslettt, B. 2013. Hemerocallis lilioasphodelus L. (Hemerocallidaceae). Yellow Day-Lily. Flowers photographed in visible and ultraviolet light. http://www.ultraviol...ellow-day-lily/ Hemerocallis lilioasphodelus L.Syn. Hemerocallis flava L.NO: Gul dagliljeSE: Gul dagsliljaDK: Gul DagliljeFI: KeltapäivänliljaDE: Gelbe Taglilie EN: Yellow Day-lily; Lemon Lily This is an elegant, medium tall plant originating from eastern Asia and widely cultivated and naturalised elsewhere. Parts of the plant are edible or have been used in Asian medicine. The showy yellow flowers appear in late spring to early summer to make it an attractive enhancement of gardens. Garden escapes are common and H. lilioasphodelus is fully naturalised in parts of Europe, but rarely seen far away from urbanised areas. Plants collected and photographed near Oslo, Norway, 21 Jun 2010. Image reference: HEME_LIL_I1006211397_VIS.jpgVisible light: Nikon D3S, Medical-Nikkor 120 mm f/4 lens, built-in ring flash. Image reference: HEME_LIL_I1006210768_UV.jpgUltraviolet light: Nikon D40X, UV-Nikkor 105 mm f/4.5 lens, Baader U2" (Venus) filter, SB-140 flash. In UV there are large basal patches on the tepals. Traces of iridscence are observable there. Anthers are dark but their filaments are quite UV-bright. The flowers are coloured differently on the abaxial side as well and this makes the buds appear in darker hues than the opened flower. [Published 28 Apr 2013] Link to comment
