BLACK BELT MOSSES AND LIVERWORTS.

BLACK BELT MOSSES AND LIVERWORTS. Donna H. Miller, Harvey A. Miller, Shiloh Jones and Paul Sparkman, Dept. of Biology & Environmental Science, Univ. of W. Ala., Livingston, AL 35470.

The Black Belt Physiographic Province extends across Alabama in a gentle are from southern Pickens and northern Sumter counties eastward through Montgomery and ending at the junction of Bullock, Mason and Russell Counties. Because of the extensive chalk exposures and the shallow soils over the chalk, the vegetation differs markedly from that in other areas of the state. Despite the unique nature of the black belt area, little seems to have been published concerning the botany of the area, especially for the mosses and liverworts. Montgomery County has the largest reported flora with 28 mosses and no hepatics reported but these are not all from the black belt area. Our field studies have added dozens of new county records within the black belt and unusual or rare species have been discovered including Pleurochaele squarrosa, several Tortella species and Tortula propagulosa which appears to be new to Alabama. Liverworts found include several species of Fraullania, Lejeunea, Porella. Pellia, and Reboulia. Corre lations were found between the Black belt bryophytes and those known from the chalk downs of England.
