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.

The graceful retroflexed petals with their green ribs give Black Beauty a pretty back view.

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?
