"There are two Trilliums known as Toadshade or Toad Trillium. Both have mottled, stalkless leaves and maroon or sometimes greenish petals and are usually less than 30cm (1') high. The flowers are not stalked. T. sessile is the smaller of the two with leaves only to about 7.5cm (3") long and flowers to 4cm (1.5"). It is common in the midwest and as far east as western New York and as far south as Georgia.
T. cuneatum has leaves to 15cm (6") long and petals to 7.5cm (3") long. It is common from Kentucky and North Carolina south to Florida.

Similar Species: T. luteum is very much like T. cuneatum except for having bright yellow or green petals and more mottled leaves. T. stamineum is found on the costal plan and has a somewhat hairy stem and twisted purple petals."
