| 1 | Ames 36305 | Cook/St. Louis Counties | Salix pellita Andersson | Minnesota, United States | NC7 |  | | 2025 | | | | | | | Wild material | Satiny willow is a tall shrub that reaches its southern limits across the extreme northern and northeastern portions of the U.S. Plants can reach 4-5 meters in height and are identified by typically dense hairs on the lower surface of leaves that are straight and lie flat. Dormant twigs are noticeably yellowish. Leaf morphology is similar to that of S. candida and S. petiolaris. Satiny willow in nature tends to be restricted to wet habitats such as riverbanks and shorelines and its presence quickly disappates the greater the distance away from open/available surface water. This accession represents genetics from the northeastern portion of Minnesota. Satiny willow is tracked (listed Threatened in 2013) by the Minnesota Department of Natural Resources and has only been documented in three Minnesota counties in the extreme northeast corner of the state. After years of targeted surveys, only eight populations have been documented since 1996. | 2172670 | Ames 36305 |
| 2 | Ames 35877 | Gallagher Fen | Salix myricoides Muhl. | Ohio, United States | NC7 |  | | 2022 | COLLECTED | 06/28/2022 | Gallagher Fen State Nature Preserve located just east, northeast of Springfield approximately 4.5 miles, T5E R9N NE 1/4 NE 1/4 Sec. 11 | 39.93209100, -83.72390500 | 307 | Remnant wetland occurring primarily where the marl meadow meets the stream and marl mud flats. | Wild material | Bayberry willow is native to areas of the northeastern U.S. and north into Canada, localized around the Great Lakes region. Known to occur on shorelines/dunes but also in swamps, fens, and on talus (Haines 2004) with the potential to reach six meters in height (Dorn 1995). Ornamental characteristics include glaucous lower leaf blades that appear chalky white. This disjunct population was sampled in southwestern Ohio (Gallagher Fen) where the species is currently (2022) designated as a potentially threatened species in the state. Specimens observed in nature were low, mounding shrubs measuruing 16-24" (40-60 cm) tall; stems were slender, red and glossy with prominent lenticles; bud scales red, darkening following opening; flowers on staminate individuals with dense whitish bracts opening to reveal stamens tipped with bright yellow anthers and pistillate flowers with pale green pistils tipped with paler stigmas. | 2138175 | Ames 35877 |

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 northeastern Minnesota. Specimens sampled in nature ranging from 6-22' in height. | 2138039 | Ames 35807 |

This collection was discovered in 2011 and represents the first report of the species for the state of Michigan (Ryskamp and Warners 2012) and thus represents a widely disjunct population where the next nearest documented population is in southern Ohio (Clermont County). | 2110277 | Ames 35615 |
| 6 | Ames 34431 | JDC/SC/2019/001/880 | Salix candida Flüggé ex Willd. | Iowa, United States | NC7 |  | | 2019 | COLLECTED | 05/17/2019 | Private property approximately 2.2 miles southwest of Oelwein, T91N R9W SW 1/4 SE 1/4 Sec. 30. | 42.65929300, -91.94916200 | 311 | High-qulity fen, remnant. | Wild material | Plants at collection site in nature averaging 2.0-2.5' in height with minimal branching. Pubescent stems mostly near apical ends. Most plants estimated at 25 ramets per genet. Estimated number of ramets per genet is difficult to separate/distinguish. This petite, shrubby willow is essentially restricted to cold bogs/fen communities and is rare in Iowa (Nekola 1990). It is easily recognized by its narrowly and extremely pubescent leaves. Salix candida was considered extirpated from Iowa by Spence (1959) and Roosa and Eilers (1978). Since discovery of eastern Iowa fen communities in 1984 it has been observed extant at 26 sites (Nekola 1988) and is tracked as a species of special concern by the Iowa Department of Natural Resources Natural Areas Inventory (2021). | 2091747 | Ames 34431 |

| 13 | Ames 32848 | Williams Prairie | Salix petiolaris Sm. | Iowa, United States | NC7 |  | | 2014 | COLLECTED | 11/23/2014 | Williams Prairie State Preserve approximately 3 miles north of Oxford, T80N R8W SW1/4 NE1/4 Sec. 5. | 41.76753000, -91.80115800 | 222 | Wet remnant prairie. Very floristically diverse, high-quality site. | Wild material | Slender-leaved willow, Salix petiolaris, is a somewhat dense suckering shrub that can reach up to 10' in height with slender stems that branch minimally, but typically maintains a height of 5-8'. 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 eastern, central Iowa from the south, southwestern edge of the species native range. Plants sampled in nature were multi-stemmed (e.g. avg. 20-75 ramets per genet) shrubs averaging 4.5' in height. Each genet typically encompassed a 5' x 5' area with branches very flexible at base; stems glabrous; buds brown; stems attractive, variable from red to orange to yellow, but mostly red; two stamens per staminate flower, no hairs; filaments separated (not fused); anthers with yellow pollen; flowering branchlet on staminate and pistillate catkins measuring 3 mm and hairy; ovary approximately 2 mm at receptivity, hairy; both pistillate and staminate bracts hairy, not toothed; and flowers appearing shortly before leaf emergence. Peak flowering and fall color generally occur in mid-April and early October, respectively in central Iowa. | 1921869 | Ames 32848 |
