Latitude/Longitude was derived from the Township, Range, Section location. This causes an imprecision.
Algific slope: an area with a conspicuously open understory dominated by Cystopteris bulbifera and Carex media, ca. 8 by 25m insize, perched widthwise on a wooded hillside; soil is 2 to 8 inches of rich humus over loose limestone talus that is refrigerated by cold (40* F) air emanating from subterranean channels in the hillside. Surrounding woods dominated by Tilia americana, Acer saccharum, Quercus (Q. velutina?), Fraxinus (F. nigra?) and Betula papyrifera; largest trees to ca. 12in. DBH. Infructescence drooping, spikelets pendent. Cespitose in large clumps (10 to 20 cm diam). Scarec in openings of algific slope and scattered in surrounding woods, seemingly favoring openings.
