Vascular Plants of Lee County.

A floristic survey of the vascular plants of Lee County, located in east-central Texas, was conducted from November 2002 through May 2005. The county is situated at the confluence of several vegetation zones, of which post-oak savannah and blackland prairie are the most widespread. Additional vegetational-floristic influences include eastern deciduous forest, mesquite scrubland, and Edwards Plateau vegetation. Soils are Eocene in origin, including the Carrizo sand formation, which supports a unique floral (and faunal) community. Climate is humid and subtropical, with 36 inches rainfall per year. Eight habitat types were recognized, and fieldwork consisted of visiting these areas repeatedly throughout the year. The annotated checklist contains the first authorís voucher collections with additional records from local herbaria. To date, the checklist includes 117 families and ca. 600-650 species for the county, with a projected 40% as new county records. The largest families are Asteraceae, Fabaceae, Poaceae and Cyperaceae. A key to the graminoids (Poaceae, Cyperaceae, Juncaceae) is also in preparation.
