Chad, I've not looked for a difference in the flowers - I'll have to check this fall. That said, I know female trees that have attractive flowers, so...
Stan, Neolitsea is confined to eastern Asia and Australia, so I'm not surprised you haven't heard of them. Litsea is found in both hemispheres. I first ran into the genus in Florida years ago when we saw Litsea aestivalis on a botanical field trip. Now I'm in the heart of their territory. Of the local Neolitsea, I like N. aciculata for its elegant foliage and beautiful purple-red flowers: http://www.geocities.jp/nisi175812/inugasi0.htm
Litsea also have some nice locals including L. acuminata: http://kanon1001.web.fc2.com/foto_sinri ... _no_ki.htm
and L. coreana (syn. L. lancifolia): http://forests.world.coocan.jp/flora/laur-4.html
Really wonderful trees. Both would do well in your area I'm sure.
