It seems that Nutaku has updated the description of some Flower Knights :

Edelweiss is now Edelle Weiss,
Star Lily true name is Lily Maculatum,
Hypericum is named Otogi Risou,
Leucocoryne is Leuco Coryne (not much change for this one),
Calla is Zantedeschia,
Geranium is Gera Cranesbill,
and of course Orchid Wilder is now Oncidium.

I don't have all the characters (obviously), so maybe it's not the only changes!
