Retroactive Post 9/17......Botanizing along the Cahaba River sout of Birmingham

Fred Spicer (below), the Director of the Birmingham Botanical Garden and Patrick Daniel (right), the curator of the Kaul Wildflower Garden, guided us on our exploration of the peculiar flora of the Ketona Dolomite Glades along the Cahaba River.

Bibb County, Alabama is famous for the uncommon and endemic species that populate exposures of the Ketona Dolomite. Magnesium is a trace element, required by plants in very small amounts; higher amounts are toxic and the Ketona Dolomite is high in magnesium. Only specialized plants live there including a number of endemics. We saw most of them and collected seed from a few. A Botanical Lost World: Bibb County Alabama is a wonderful short summary of the flora.
