Andrea B. Posted July 31, 2013 Share Posted July 31, 2013 Blum, A.G. (2013) Lilium henryi Baker x speciosum Thunberg 'Black Beauty' (Liliaceae) Orienpet Lily. Flowers photographed in ultraviolet and visible light. http://www.ultraviol...-orienpet-lily/ Middletown, New Jersey, USA28 July 2013Cultiver in home garden Comment:Black Beauty is a cross between Henry's Lily, L. henryi, a Trumpet lily and the Japanese Lily, L. speciosum, an Oriental lily - thus becoming an Orienpet lily. The green grooves at the base of the petals produce nectar.This lily is UV-dark, but dense conical cells on the petals produce a strong, bright iridescence where the UV light rakes across them.

nfoto Posted March 15, 2015 Share Posted March 15, 2015 Now, that is a really convincing evidence that those shimmering or 'greyish' areas of the corolla in fact are conical cells. Ready for the text books? Link to comment
