About this title

Purdue University Press


This reference tracks the distribution of approximately 200 common weed species throughout Indiana's 92 counties. Each weed's distribution is shown on range maps at three times -- 1899, 1940, and 2004. The Overleases' compendium records the continuing expansion of weeds, aggressive plants that can move into an available habitat, across Indiana. The book itself is also one that continues the timeline of two other major studies of the Hoosier state - Stanley Coulter's 1899 catalog of Indiana plants and Charlie Deam's 1955 flora of Indiana.
