17768 Tigerlily           Discovered 1998 Mar. 3 by T. Urata at the Nihondaira Observatory.
In Lewis Carroll's Through the Looking Glass and what Alice found there, Alice comes upon a large flower-bed with a border of daisies and a willow-tree growing in the middle. The Tiger-lily tells Alice that all the flowers can talk as well as Alice---and a great deal louder.
