Indicator Species  
Showy Tick-trefoil (Desmodium canadense)  

 

This member of the pea family has large 1 cm (½ inch) rose-purple flowers arranged in dense racemes at the top of a hairy, leafy stem.  Like many other prairie wildlfowers, showy tick-trefoil depend on bees and other insects for pollination.  Tall and robust, it reaches 1.8 m (6ft) in height, almost as tall as some of the grasses it grows with.  The leaves are clover-like and divided into three leaflets, the middle one with a long stalk.  The seed pods have 3-5 joints and are very sticky when mature, clinging easily to clothing or fur.
