Systematics and botanical history

Of the numerous Untertaxa described, the plurality based on characteristics which are caused by infection with Mycoplasma, and are therefore discarded. Only a Untertaxon is currently recognized, namely:

• Trillium grandiflorum roseum f: salmon - pink colored, especially in the Blue Ridge Mountains in Virginia. The shape is popular as an ornamental plant.
