1. Androsace occidentalis Pursh. Map 1591. Reported for the state by 

 Dorner (Proc. Indiana Acad. Sci. 1903: 119. 1904), who says "somewhat 

 abundant in lowland near Wea Creek." I have one of his specimens, and 

 one from Knox County, without data, collected by W. S. Blatchley. It is to 

 be noted that the area along Big Wea Creek has many western species 

 such as Muhlenbergia cuspidata, Arenaria patula, Lithospermum incisum, 

 and others.
