The primary soil type in the collection area is classified as Tusquitee loam, 10 to 25 percent slopes. The Tusquitee series consists of very deep, well drained soils on gently sloping to very steep benches, foot slopes, toe slopes, and fans in coves in the Southern Blue Ridge mountains, MLRA 130B. These soils formed in colluvium derived from materials weathered from igneous and high-grade metamorphic crystalline rocks such as granite, mica gneiss, hornblende gneiss, and schist.

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.

Gray | Pennsylvania, United States | NA | | | 2021 | COLLECTED | 11/16/2021 | Plants growing in woodlands along a small unnamed creek corridor dumping into the Middle Branch White Clay Creek in Goddard Park, West Grove Pennsylvania, off of Wickerton Road, Chester County. | 39.81063861, -75.82750806 | 124 | Plants are growing in a range of habitats from mesic woodlands to saturated streamside settings of deciduous woodlands that drain toward the Middle Branch White Clay Creek. Plants grow in high understory shade with dappled to indirect sunlight. The only female (fruiting) plants were found in areas along the creek where soils are moist to saturated. Numerous male specimens were found in the areas described above. Soils: Soils found in the areas where this collection was made are comprised primarily of Baile silt loam (Ba), Hatboro silt loam (Ha), and Glenelg silt loam, 8 to 15 percent slopes (GgC). Baile silt loam consists of very deep, poorly drained, moderately low to moderately high saturated hydraulic conductivity, soils on upland depressions and footslopes that were formed in local alluvium over residuum from acid crystalline rocks, chiefly mica schist and granitized schist and gneiss; slope ranges from 0 to 8 percent. Hatboro silt loam consists of very deep and poorly drained soils formed in deposited alluvium derived from metamorphic and crystalline rock. They are on flood plains. Slopes range from 0 to 3 percent. Glenelg silt loam, 8 to 15 percent slopes consists of very deep, well drained soils formed in residuum weathered from micaceous schist on uplands of the Blue Ridge and the Northern Piedmont. This soil is undifferentiated, mostly poorly drained sandy bottomland soils intermingled with decomposing organic litter and eroded silts and clays due to erosion. Slope: 0 to 15% Aspect: Variable. | Wild material | | 2123125 | NA 86885 |

Plants are growing in high understory shade with very little direct sun during most of the day. The remnant woodlands exist mostly along the steep slopes, wetlands and seeps of seasonal and year-round creeks flowing into the Middle Branch White Clay Creek. The woodlands are bordered by numerous housing developments and land converted to meadows; hence there is significant first order edge that is heavily impacted by invasive plant intrusion. Soils: Soils are classified as Glenelg silt loam, 8 to 15% slopes (GgC); this series consists of very deep, well drained soils formed in residuum weathered from micaceous schist on uplands of the Blue Ridge and the Northern Piedmont. Saturated hydraulic conductivity is moderately high in the subsoil and moderately high to high in the substratum. This upper horizon of this soil is undifferentiated, mostly poorly drained sandy bottomland soils intermingled with decomposing organic litter and eroded silts and clays due to erosion.
