Trillium recurvatum
''Trillium recurvatum'', the Bloody butcher or Prairie trillium, is a member of the Melanthiaceae family. It occurs in parts of the central and eastern United States from Iowa south to Texas and east to North Carolina and Pennsylvania,〔(Trillium recurvatum ) web page from (Vanderbilt Bioimages )〕 usually mesic deciduous forest, including tallgrass prairie savannah. Trees which frequently shade this trillium include oak, maple, ash and hickory.〔(Prairie Trillium ), web page from (Illinois Wildflowers )〕
The blossom has three brown to maroon petals that are typically under long. The petals are recurved, with tips converging over the stamens.〔Dan Tenaglia, (Trillium Recurvatum ) web page from (Missouri Plants )〕 The fruit has 6 well developed ridges (see photo). The seeds include structures known as elaiosomes, to promote dispersal by ants and other foraging insects.
==Conservation status==
Globally, the prairie trillium is considered to be secure (G5), but several states at the edge of its range have listed it. In Wisconsin, it is considered rare or uncommon (S3) and therefore a species of special concern.〔(Reflexed Trillium (Trillium revurvatum) ), Endangered Resources Program Species Information, (Wisconsin Department of Natural Resources ). 〕 In Michigan, it is considered a state threatened species and is protected by law (S2S3).〔(Trillium Recurvatum ), Michigan Natural Features Inventory, Lansing.
