Vascular Flora of St. Francis National Forest in Arkansas

ABSTRACT
St. Francis National Forest is at the southernmost end of Crowley’s Ridge in Lee and Phillips Counties of Arkansas. Most of the Forest is located on Crowley’s Ridge and has narrow ridges and valleys carved into the loessal soils. A small portion of the Forest is located along the Mississippi and St. Francis Rivers and is characterized by level, alluvial soils. This study identified 104 vascular plant families, 285 genera, 424 species and 11 subtaxa on the Forest. The study was begun in the fall of 1989 and completed in the spring of 1991.
