Justicia Linnaeus. Water-willow.
A genus of 600 or more species, herbs and shrubs of the tropics and warm temperate North America. Justicia as circumscribed is highly polyphyletic and will need to be expanded further or split into smaller, monophyletic units. Any splitting will remove Justicia from our native flora, as the type of Justicia is Old World, and all the New World taxa form a separate clade.
