The woodlands are primarily deciduous with a few evergreens infrequently mixed. Slope: 15 to 30 percent. Aspect: Northeast. Soil: The primary soil type in the area of this collection is classified as Rockland Series sandstone (Rc). The Rockland series consists of well drained soils formed in loamy colluvium from rotational landslides on slopes of stream valleys and dissections of ground moraines. Saturated hydraulic conductivity is moderate in the upper part of the profile and moderately slow in the lower part. Slopes range from 18 to 70 percent. Some pedons have buried leaves, twigs, and moss. Mass soil movement has left random remnants of soil structure from prior upslope soil development and has buried tree branches, leaves and moss. The upper 0-2 cm of soil contains slightly decomposed organic matter while lower soils layers to a depth of 58 cm are comprised of dark reddish-brown to brown silt loam and are moderately acidic. Below 58 cm the soils are generally dark reddish-brown silt loam and strongly to moderately alkaline. (Source:California Soil Resource Lab/NRCS Official Soil Series Descriptions).

Vegetation of this area is very much defined by small changes in elevation that go from wet to very dry. Ilex glabra remains abundant throughout, though. Slope: N/A. Aspect: N/A. The underlying geology of this area is the Cohansey Formation of middle Miocene origin and comprised of sand, white to yellow with local gravel and clay. It is sometimes locally stained red or orange brown by iron oxides and (or) cemented into large blocks of ironstone. Unweathered clay is typically dark gray, but commonly weathers white where it is interbedded with thin beds of ironstone. Sand is typically medium grained and moderately sorted although it ranges from fine to very coarse grained and from poorly to well sorted. Sand consists of quartz and siliceous rock fragments. Some beds are locally micaceous. Maximum thickness in the map area is about 60 meters; however, thickness is difficult to determine because of the irregular basal contact and extensive post-depositional erosion. (Source: USGS New Jersey Geologic Map Data). The primary soil type in the area of this collection is classified as Mullica Series sandy loam, 0 to 2 percent slopes. These soils are typically coarse-loamy, siliceous, semiactive, and mesic typic humaquepts that are strongly to extremely acidic throughout the profile. The typical solum thickness ranges from 50-150+ cm. These soils are generally considered to be poorly drained. (Source: NRCS Web Soil Survey). | Wild material | | 2169930 | NA 88593 |

Plants were also found growing on the slopes of the dam in well-drained mesic to dry-mesic conditions. This species is clearly adaptable to a variety of conditions. Slope: 0 to 15 percent. Aspect: East. Elevation: 28 to 30 meters. NOTE: In addition to the soil type described below, this species was also growing on the slopes of a constructed earthen dam of unknown soil origin. The underlying geology of this area is of Middle Miocene, Serravallian origin and characterized as an Cohansey Formation. It is comprised of sand, white to yellow with local gravel and clay. Locally stained red or orange brown by iron oxides and (or) cemented into large blocks of ironstone. Unweathered clay is typically dark gray, but commonly weathers white where interbedded with thin beds of ironstone. Unit is a complex of interfingering marine and nonmarine facies. Sand is typically medium grained and moderately sorted although it ranges from fine to very coarse grained and from poorly to well sorted. Sand consists of quartz and siliceous rock fragments. Some beds are locally micaceous. In general, the sand is crossbedded, although the style of crossbedding varies significantly with the paleoenvironment. Trough crossbedding predominates, especially in the nonmarine channel fill deposits, and the scale of the crossbeds varies from small to large. Maximum thickness in the map area is about 60 m; however, thickness is difficult to determine because of the irregular basal contact and extensive post-depositional erosion. There is as much as 18 m of relief along the basal contact. The basal contact is sharp, undulatory, and directly overlain by a thin gravel bed. The Cohansey Formation unconformably overlies the Kirkwood Formation and is found in channels cut down into the Kirkwood. Where the Kirkwood consists of sandy, light-colored sediments, the basal contact of the Cohansey is drawn below crossbedded sediments. Where the Kirkwood consists of dark-colored silty beds, the basal contact is drawn between light-colored Cohansey sediments and the underlying dark-colored sediments. The Cohansey was markedly thinned because of erosion prior to deposition of overlying units in the western and southern parts of the southern sheet. The unit has been extensively eroded and stripped from large areas of the New Jersey Coastal Plain, particularly in the central sheet where outliers are common. In spite of its widespread nature, the Cohansey is poorly exposed because of its loose sandy composition, which causes it to erode easily. (Source: USGS New Jersey Geologic Map Data.) The primary soil type in the collection area is classified as Manahawkin Series muck, 0 to 2 percent slopes, frequently flooded, Northern Coastal Plain. Manahawkin Series soils are very deep, very poorly drained soils that are sandy or sandy-skeletal, siliceous, dysic, mesic Terric Haplosaprists high in organic deposits that are found in lake basins, back swamps, floodplains, and freshwater channels. The soils are classified in the dysic reaction class because pH in water dominantly ranges from 4.5 to 5.0. The zone from the soil surface to a depth of 200 cm is continuously saturated (endosaturation). The upper strata of Manahawkin Series from 0 to 76 cm is black broken face and rubbed muck; 10 percent fibers, less than 2 percent rubbed; moderate medium granular structure; mat of many fine roots; identifiable material is primarily herbaceous with a trace of woody fragments; 85-95 percent organic matter; extremely acid. Lower strata to 200 cm are gray sand, single grained and loose; strongly acid. (Source: NRCS Web Soil Survey.) | Wild material | | 2159120 | NA 88692 |

The primary soil types in the area of this collection is classified as Atsion sand, 0 to 2 percent slopes, Northern Tidewater Area and Downer loamy sand, 0 to 5 percent slopes, Northern Coastal Plain. Atsion Series soils are very deep, poorly drained with moderate to rapid permeability above 70 cm and slower beneath. They are classified as sandy, siliceous, mesic Aeric Alaquods. The upper stratum from 0 to 25 cm is dark gray sand, dry, single grained and lose with many fine roots. It is extremely acid. Lower strata are light gray to dark brown with small percentages of rounded quartzose pebbles and are extremely acid. Downer Series soils are very deep, well-drained soils that are coarse-loamy, siliceous, semiactive, mesic Typic Hapludults. The upper stratum of Downer Series from 0 to 25 cm is dark grayish brown, brown loamy sand that is dry with weak fine granular structure. It is very friable and strongly acid. Lower strata from 25 to 76 cm are yellowish brown single grain, loose loamy sand with few extremely weakly cemented masses of oxidized iron in the lower part. This layer is very strongly acid.

Common on this site, but otherwise infrequent. This species is near the southernmost end of its natural range. | 31.52053400, -85.02351600 | 53 | Plants are growing in part-shade to shade of deciduous upland, dry, deciduous woodlands on steep slopes 10-15 meters above Kolomoki Creek. Soils: The underlying geology of this area is of Paleocene origin and characterized as Tuscahoma Sand. As mapped this formation includes lower Eocene Bashi Marl Member of the Hatchetigbee Formation. This formation consists of light-gray to light-olive-gray laminated and thin-bedded carbonaceous silt and clay interbedded with fine sand; thin lignite beds occur locally. Lower part of the formation includes beds of fossiliferous, glauconitic fine quartz sand containing spheroidal sandstone concretions, gravel and clay pebbles. Source: USGS Georgia Geologic Map Data (https://mrdata.usgs.gov/geology/state/sgmc-unit.php?unit=GANu%3B1) The primary soil types in the collection area are classified as Ailey-Cowarts Complex Series soils (8 to 25 percent slopes). The Ailey Series consists of well drained or somewhat excessively drained soils formed by fluviomarine and marine deposits. These soils are found marine terraces and low hills of the upper coastal plain and sandhills; they are strongly acidic. The Cowarts Series consists of very deep, moderately well and well drained soils on ridge tops and side slopes on uplands of the Coastal Plain Major Land Resource Area. They formed in loamy marine sediments. Slopes range from 1 to 60 percent.

Don | New Jersey, United States | NA | | | 2022 | COLLECTED | 10/24/2022 | Plants growing on both sides of Duerer Street approximately 0.37 kilometers southeast of 4th Avenue, Mullica Township, New Jersey. Plants are common but scattered on both sides of the road at this site. | 39.55730700, -74.66376100 | 22 | Plants grow from part shade to full sun throughout the habit from the upper edges of the ditches through the herbaceous grass dominant buffer and all the way to the part shade of the woodland edge. Plants transition through moist/wet conditions in full sun to quite dry conditions in part shade and seem equally adapted. Soils: The underlying geology of this area is the Cohansey Formation of middle Miocene origin and comprised of sand, white to yellow with local gravel and clay. It is sometimes locally stained red or orange brown by iron oxides and (or) cemented into large blocks of ironstone. Unweathered clay is typically dark gray, but commonly weathers white where it is interbedded with thin beds of ironstone. Sand is typically medium grained and moderately sorted although it ranges from fine to very coarse grained and from poorly to well sorted. Sand consists of quartz and siliceous rock fragments. Some beds are locally micaceous. Maximum thickness in the map area is about 60 meters; however, thickness is difficult to determine because of the irregular basal contact and extensive post-depositional erosion.

Collector's note on the name under which this material was gathered, Styrax americanus var. pulverulentus: "In general, the var. pulverulentus is considered "taxonomically inconsequential" by many botanists. Even so, this densely pubescent characteristic is highly uniform across every plant I observed in the sampled population. Weakley notes that "true" var. pulverulentus can be found as far west as East Texas and, in my humble opinion, the population sampled herein represents this "taxon". Regardless, for the purposes of drawing distinction between "typical" Styrax americanus and the densely pubescent form, I've chosen to use this varietal name. It will be interesting to observe whether the seedling progeny are uniformly similar to their parents when they germinate."
