Rocky woodlands along Furnace Creek as well as steep rocky slopes above Pulpit Rock Reservoir associated with the Pulpit Rock and Pinnacle Loop Trail. | 40.59226100, -75.94588800 | 301 | Well-drained and very rocky dry deciduous woodlands in part shade to full shade. Slope: 0-30%. Aspect: variable. The underlying geology of this area is of Silurian origin and characterized as the Shawangunk Formation. It is characterized by light- to dark-gray, fine- to very coarse-grained sandstone and conglomerate containing thin shale interbeds. Includes four members, in descending order: Tammany--conglomerate and sandstone; Lizard Creek--sandstone and red or green shale; Minsi--sandstone and conglomerate; Weiders--conglomerate. Tammany and Lizard Creek Members together are approximately equivalent to Clinton Group to the west; Minsi and Weiders Members together are equivalent to Tuscarora Formation to the west. (Source: USGS Pennsylvania Geologic Map Data). The primary soil type in the collection area is classified as Hazleton Series. The Hazleton series consists of deep and very deep, well drained soils formed in residuum of acid gray, brown or red sandstone on uplands. Slope ranges from 0 to 80 percent. Permeability is moderately rapid to rapid. Solum thickness ranges from 60 to 120 centimeters. Depth to lithic contact ranges from 1 to 2 meters. Rock fragments of angular sandstone, dominantly less than 25 cm in size, range from 5 to 70 percent in individual horizons. Boulders, stones, flags and channers cover about 5 to 60 percent of the surface of some pedons. Reaction ranges from strongly acid through extremely acid throughout.

| 1 | NA 89033 | RJL2022MD-010 | Clethra alnifolia L. | Maryland, United States | NA | | | 2022 | COLLECTED | 09/15/2022 | Plants growing in low woodlands at the end of Greenway Avenue near a boat dock that leads to the Pocomoke River, adjacent to Winter Quarters Golf Course, Pocomoke City. Plants common throughout the wetland area as well as mesic edges of the woodlands. | 38.08305100, -75.56527800 | | Plants growing in the flood plain of the Pocomoke River in shade to part sun of a mixed deciduous and evergreen bottomland habitat about 10 meters from the edge of the golf course fairway. The habitat is a mucky swamp edge habitat next to the Pocomoke River, most of which seems wet year-round and grades slightly upslope to more mesic conditions.
The underlying geology of this area is comprised of Quaternary Deposits of Wisconsin to Holocene origin. The composition is primarily undifferentiated gray to buff sand and gravel, gray to brown lignitic silt and clay, occasional boulders, and rare shell beds. Surficial deposits occur as shell-bearing estuarine clays and silts.

The surface soil profile of this habitat is classified as Puckum Muck which is frequently flooded. These highly saturated soils are found in flats, depressions and swales. The soil reaction of Puckum Muck is extremely acid to strongly acid throughout the profile. The depth to bedrock is generally greater than 150 cm. Wood fragments comprise 0-25%, by volume of the Puckum Muck throughout the profile which includes mostly twigs, branches, logs, or stumps and are 1.5-30 cm in diameter. The composition of these highly saturated soils, are classified as muck (sapric soil material) or mucky peat (hemic soil material) throughout most of the upper 150 cm and may contain thin layers of mucky silt loam, silty clay loam, sandy loam and/or sand.
