Slope: 5-10%. Aspect: East. The underlying geology of this area is of Mississippian origin and characterized as the Burgoon Formation. It is comprised of buff, medium-grained, cross bedded sandstone that includes shale and coal. In some places, it contains conglomerate at base as well as occasionally contains plant fossils; equivalent to Pocono Formation of Ridge and Valley province. (Source: USGS Pennsylvania Geologic Map Data). The primary soil type in the collection area is classified as Wellsboro Series. The Wellsboro Series consists of very deep, moderately well- and somewhat poorly-drained soils formed in till derived from red sandstone, siltstone, and shale. Slope ranges from 0 to 50 percent. Saturated hydraulic conductivity is moderately high or high in the mineral surface layer, subsurface layer, and upper part of the subsoil; and low or moderately low in the lower part of the subsoil (fragipan) and the substratum. Solum thickness is greater than 102 cm. Depth to the fragipan ranges from 36 to 76 cm. Depth to bedrock is 152 cm or more. Rock fragments of subangular and rounded sandstone, siltstone or shale range from 5 to 40 percent in the A and B horizons, and from 15 to 50 percent in the Bx and C horizons. Typically, rock fragments average about 5 to 25 percent by volume above the fragipan and 15 to 40 percent by volume in and below the fragipan. Reaction commonly ranges from very strongly acid through moderately acid. (Source: NRCS Web Soil Survey). | Wild material | | 2159070 | NA 88679 |

Shining willow frequents wetland habitats such as swampy lakes, wet meadows and along rivers. Noted for it's extremely shiny, long (e.g. 7-14 cm) leaves with very elongated, acumiate leaf tips and conspicuous, enlarged glands clustered at the end of the petiole. First year branches are very glabrous and bright yellow to bright orange in color. Flowering tends to occur later in spring in comparison to other shrubby willows e.g. Salix discolor, Salix humilis, Salix petiolaris, and Salix eriocephala. Shining willow can often be confused with Salix serissima, but the presence of glands at the base of the petiole, the colorful first year stems (most noticeable in winter) of Salix lucida can be used to separate them. The native distribution of Salix lucida is concentrated in the northeastern U.S. with scattered disjuncts as far west as North Dakota and as far south as the northern tier of counties in Illinois, Indiana, and Ohio (Little, E. L. Jr. 1977). This accession represents genetics from northeastern Wisconsin.

L. Jr. 1977). Generally adapted/tolerant to wet soils this species is often found in meadows, fens, swamps, and streambanks. Attractive ornamental characteristics includes early spring, showy flowers and yellow foliage in the fall. Salix discolor provides a critical source of pollen at the beginning of the growing season for a plethora of pollinators and also serves as a larval host to many insect species. Salix discolor are commonly used in the cut flower industry for both their showy catkins and colorful, dormant winter stems. This accession represents genetics from central Wisconsin. Plants in nature measuring approximately 8-10' in height occassionally up to 25' with brown to red-brown stem colors on most recent year's growth.

Native to North America, the native range covers mostly the northeastern US stretching from Maine to western North Dakota and Canada south to central Iowa (Little, E. L. Jr. 1977). Salix petiolaris typically dominates wetland areas including sedge meadows, marshes, riverbanks, and lake shores. Despite favoring wet habitats, it can also be found in dry, upland areas, especially those with high-water tables. However, longevity is generally limited in upland habitats. S. petiolaris, similar to other willow species, responds well to fire, coppicing, or heavy browsing (highly favored by deer) by sprouting new stems close to the crown. In cultivation, plants after five years will encompass a 5' x 5' area due to stems that arch from the main base of the plant. Coppicing of plants to ground level is highly recommended either annually or once every 3-5 years to maintain vigorous growth and plant health. This species requires substantial to full sun exposure and is an excellent choice for streambank stabilizations and windbreaks to reduce soil erosion and drifting snow, respectively. This accession represents genetics from central Wisconsin. Plants noted in nature measuring up to 6' in height. Very densely suckering clumps occassionally reaching up to 10' in diameter. Stem colors on most recent year's growth varied from orange-yellow, red (predominate), to yellow. Petioles are minutely hairy. | 2141554 | Ames 36021 |

In nature, this variety is generally found in moist habitats typically along stream banks and swamps where ample moisture is readily available. The native range of V. opulus var. americana is concentrated in the northeastern United States and into Canada (Little, E. L. Jr. 1977). Attractive ornamental characteristics includes showy lacecap flowers in spring and bright red fruits and foliage in the fall. Fruits are tart with a hint of sweetness. The European highbush cranberry (V. opulus var. opulus) is nearly identical to American highbush cranberry other than small glands (<1 mm) on the petiole making the exact determination very challenging resulting in common misidentifications. A major difference between the American and European highbush cranberries is that the European variety produces unpalatable fruit. Recent research has shown that American and European highbush cranberries are genetically distinct and that plants of hybrid origin are uncommon (Tork et al. 2025). This accession represents genetics from northeastern Wisconsin. Specimens sampled in nature noted as having bright red fruits with slight sweet taste. Based on fruit taste, this accession is currently (2026) being listed as V. opulus var. americanum. | 2141556 | Ames 36023 |

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.

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. Source: USGS Maryland Geologic Map Data https://mrdata.usgs.gov/geology/state/sgmc-unit.php?unit=MDKp%3B5 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.

Simmers. Described as a broad-leaved form of M. fistulosa, generally intermediate between M. fistulosa and M. clinopodia, with probable hybrid origin. Typcial habitat is mesic woods and edges on lowlands. In contrast to M. fistulosa, this taxon has longer petioles (usually 2-3 cm versus 0.5-2.0 cm), lower leaf surfaces with scattered spreading hairs, and corollas are paler pink at tips to almost white with peak flowering occurring prior to M. fistulosa by approximately 1-2 weeks. Leaves are rather rugose, where upper leaf tissue between veins is visibly raised. This accession represents genetics from northern Indiana (Potato Creek State Park). Plants at the collection site in nature peaked flowering near 8 July 2019 where flower colors were more lavender in sun but pale in shade (Namestnik, S., personal communication, 15 July 2020). Peak fruiting occurs mid-August. Average height of plants sampled in nature estimated at 4.5' in height. | 2097752 | Ames 35216 |

A deciduous shrub that grows from 1 to 5 m tall. Bark color ranges from olive-brown or gray in older branches to yellowish-brown in younger branches, and the youngest twigs are glossy red-brown. The leaves of mature branches are dark green and shining on the top surface with a broad whitish midrib, and paler on the bottom surface. Leaves are elliptic or lanceolate with minutely toothed margins and the distinguishing presence of glands on the petiole near the base of the leaf blade. S. serissima flowers from May to July, and fruits mature from June to September (Decker 2006). Staminate flowers are rather showy and stout measuring approximately 45-55 mm in length and 15 mm in width that peak well after leaves have emerged; anthers yellow and dense. Pistillate catkins are rather loosely flowered and slightly shorter (e.g. 25-30 mm in length) in comparison to staminate flowers; green and inconspicuous. | 1968259 | Ames 34360 |
