(Source: USGS Pennsylvania Geologic Map Data.) The primary soil type in the area of this collection is classified as Gladstone Gravelly Loam Series (8 to 15 percent slopes). The Gladstone Series consists of very deep, well drained soils formed in residuum and colluvium from granitic gneiss. Saturated hydraulic conductivity is moderately high to high.

Gravel content ranges from 5 to 35 percent throughout the solum, and 10 to 40 percent in the C horizons. Fragments, larger than 3 inches in diameter, range from 0 to 20 percent by volume in the surface layer and 0 to 10 percent in the subsoil and substratum layers. Reaction is strongly or very strongly acid throughout the soil, unless limed. Areas that have been limed range to moderately acid in the upper part of the profile.

Slope: 2-10%. Aspect: Variable. The underlying geology of this area is of Triassic origin and characterized as the Stockton Formation. It is characterized by light-gray to buff, coarse-grained, arkosic sandstone; includes reddish-brown to grayish-purple sandstone, siltstone, and mudstone. (Source: USGS Pennsylvania Geologic Map Data.) The primary soil type in the area of this collection is classified as Edgemont Channery Sandy Loam Series (8 to 25 percent slopes), extremely stony. The Edgemont Series consists of deep and very deep, well drained soils formed in the weathered residuum of quartzitic rocks. They have moderately high to high saturated hydraulic conductivity. Slopes range from 0 to 70 percent. Solum thickness ranges from 50 to 10 cm. Depth to bedrock ranges from about 1.5 to 2.2 meters. Kaolinite is the dominant mineral in the clay fraction with detectable amounts of illite, vermiculite, montmorillonite, chlorite and interstratified clays. Gravel, channers, and stone size fragments of quartzite and quartz are present throughout the profile. Rock fragments range from 5 to 40 percent in the horizons of the solum and from 10 to 90 percent in the C horizon. Reaction ranges from extremely acid to strongly acid throughout.

| 4 | NA 88514 | RJL2022MD-019 | Kalmia latifolia L. | Maryland, United States | NA | | | 2022 | COLLECTED | 11/04/2022 | Plants are growing on both sides of a fire road on Maryland Heights along the edge with Harpers Ferry National Historic Park. This location was accessed from the east where Miller Avenue meets the fire road, approximately 2 kilometers away. There is no vehicular access to the collecting area. Becoming locally uncommon. This local population is likely to be extirpated in the next 20-30 years. This collector has hiked through this area for more than 35 years and seen dramatic changes in the population. When first observed, Kalmia latifolia was a dominant understory shrub on south- to west-facing slopes beneath a mature forest canopy. Over the years, at least one forest fire has significantly reduced the population, along with a continuing increase in deer populations, resulting in catastrophic browse damage. The absence of a mature forest canopy and periods of drought have almost certainly also resulted in decline of this population. While collecting seed from scattered mature plants well above deer browse levels, this collector also noted that there was virtually no recruitment taking place. | 39.32811200, -77.72242400 | 287 | Plants are growing in part-shade to shade of a deciduous upland, very rocky, and dry forest community. Plants are frequently found growing among boulders, rock outcrops, and steep-slope erosional areas, although, not exclusively.
Soils: The underlying geology of this area is of Late Cambrian to Cambrian origin and comprised of Chilhowee Group; Weverton Formation. This includes interbedded white to dark gray, thin-bedded, micaceous, ferruginous, and sericitic quartzites, phyllites, and white, thick-bedded, ledge-making quartzites; some gray to brown ferruginous quartz conglomerate and purple-banded phyllite.

The primary soil types in the collection area are classified as Dekalb-Bagtown-Rock outcrop complex, 25 to 65 percent slopes. The Dekalb series consists of moderately deep, excessively drained soils formed in material weathered from gray and brown acid sandstone in places interbedded with shale and graywacke. Slope ranges from 0 to 80 percent. Permeability is rapid. Solum thickness and depth to bedrock range from 50 to 100 cm. Flat, subangular or angular, sandstone fragments, 2.5-25 cm across increase with depth and range from 10-60 percent in individual horizons of the solum and from 50-90 percent or more in the C horizon. The amount of rock fragments typically increases with depth. Cobbly, channery, and very stony phases are common. Reaction ranges from extremely through strongly acid.
