ABSTRACT
Vegetation and flora of the Pilot serpentine area were studied in Cecil County, Maryland. The ground layer of the 0.5 ha opening comprises 44 vascular plant taxa, including <em>Aster depauperatus</em>, <em>Sporobolus heterolepis</em>, and <em>Talinum teretifolium</em> which are rare in Maryland. <em>Sporobolus heterolepis</em> and <em>Schizachyrium scoparium</em> were community dominants, comprising 56% of total cover. <em>Sporobolus heterolepis</em> was most abundant in the perimeter of the opening which was in <em>Pinus virginiana</em> woodland and late savanna stages of succession. The non-perimeter region was mostly in grassland and early savanna stages. Drought stress was incidentally identified as an important factor inhibiting <em>Pinus virginiana</em> succession.
