Only nine populations are known (2024-2025 reconnaissance) along the upper courses of the Connecticut and Adroscoggin watersheds essentially following the border of Vermont and New Hampshire. This site was strategically targeted due to the presence of a susbtantial number of male specimens marked during flowering. Majority of other populations known either lack males completely or are represented by an extremely low percentage. This accession was collected as cuttings and represents a collection of 20 male and 20 female genotypes.

| 326 | 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 |

Donated to Dr. Olsen, who brought them to USNA. The name under which they were received is a misspelling of 'Rokkaku' (sometimes listed as 'Rokkakudo'), a male weeping willow cultivar of normal tree proportions grown from a famous tree at a temple of that name in Kyoto, Japan. The dwarf plants that we received are sometimes mistakenly called this, but are actually those otherwise traded as 'Yatsubusa', an invalid (unpublished) epithet according to the ICRA for Salix. Their leaves appear to be smaller while confined to containers, but it is questionable how dwarf they might remain if given ample space to grow. -SBL Received as: Salix 'Rokkakududai'. | 2158156 | NA 87468 |

High with peat and organic matter | Wild material | Salix serissima (autumn willow) is a boreal species and an obligate wetland species with a concentrated abundance and distribution in the northeastern portions of the U.S. and in Canada from Newfoundland to British Columbia and south to New Jersey, Illinois, and Colorado (Hornbeck et al. 2003 and Decker 2006). Disjunct populations occur in Montana, Wyoming, Colorado, and South Dakota. Only two populations occur on Black Hills National Forest lands: a large population at McIntosh Fen (Pennington County) and a small population on Middle Boxelder Creek (Lawrence County) (Hornbeck et al. 2003). This species gets its name from the late dispersal of its seeds ocurring from June through October. Salix serissima can grow to 4-5 m tall, but more typically < 3 m. Identifying morphological characteristics include brownish-yellow, glossy stems with dark green, shiny leaves that are ellpitic/lanceolate in shape with minutely toothed margins and distinguished glands on the petiole near the base of the leaf blade. Genetics from this population originate from McIntosh Fen in the Black Hills of South Dakota where only four occurrences are known in the state (Hornbeck et al. 2003). This site has historical significance tracing back to an expedition in 1874 led by Lt. Colonel George Armstrong Custer, where N.H. Winchell (faculty member at the University of Minnesota) took a photo of McIntosh Fen (see image in accession summary). Winchell served as a geologist resulting in the production of the first geological map of the Black Hills in addition to a listing of tree and shrub species noted. The name McIntosh Fen was derived from botanical work by Arthur C. McIntosh describing the fen community in 1924 as a "sedge moor", inhabited by autumn willow, sage willow, and numerous other disjunct wetland species. His work (McIntosh 1931) included sections on geology, soils, climate, paleobotany and ecology and most notably a checklist of the vascular plants totalling 1300 species (Gabel et al. 2015). The plant community described by McIntosh (1931) included a more extensive list of species than what exists at McIntosh Fen today (Hornbeck et al. 2003) and the specimen collected (McIntosh #1158 collected on 23 August 1928 (NA Herbarium)) was annotated by Carleton R. Ball as "1st record for South Dakota". | 2113452 | Ames 35657 |

The northern area is located along the Scuppernong Springs Nature Trail (intersection of State Highway 67 and County Highway ZZ) and the adjacent marsh prairie to the south. The southern area is located in the Scuppernong Prairie State Natural Area, at the intersection of Wilton Road and County Highway N. Kettle Moraine State Forest - Southern Unit, Waukesha County | 42.93363600, -88.47242400 | 260 | Marsh, riverbank, prairie and woodland. | Wild material | Shrubs noted in nature measuring 0.5 to 2 m tall. The two areas sampled contained both Salix myricoides and Salix discolor, and likely hybrids between the two species. Attempts were made to collect only Salix myricoides based on the following characteristics: white undersides of the leaves, large stipules and finely serrated leaf margins. During collection on 6 April 2021, S. discolor was in flower while S. myricoides was not yet flowering. 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. Staminate flowering occurs before or during leaf expansion with purple-turning-yellow anthers (Haines 2004). This accession was sampled on wet, slightly above neutral pH soils (6.0-7.3) which may result in superior performance in the urban landscape. Under cultivation, the plants grow in a widely spreading growth habit (some are nearly prostrate); however, this trait was not noticed at the time of collection from nature. | 2107011 | Ames 35550 |

Very diverse habitat. | Wild material | Salix pedicellaris is extremely rare in Iowa only found in the northern tiers of counties. Currently listed as a state threatened plant species and thus tracked via the Iowa Natural Areas Inventory Program (Iowa Department of Natural Resources). Only 15 sites throughout Iowa representing 13 counties have documented S. pedicellaris. Since the year 2000, only two reports (observation/herbarium specimen) have documented the species presence in Iowa. Bog willow is a small shrub (<2 meters) typically with few, short stems often hidden amongst sedges. Spreads clonally via suckering and/or layering lending it to be found in stable fen habitats with ample supply of water that see little to no distrurbance. Spring flowering typically occurring in mid-May to early June with fruiting occurring in early June in Iowa. Little to no existance in cultivation. Leaves are rather waxy and significantly repels water. During a growout of original plant material (sampled as cuttings from collection site in nature) at NCRPIS in Ames, Iowa exectued in 2020, a total of 45 genets were identified as female (14) and male (31) on 4 May 2022 and 17 April 2023 during peak flowering. | 2105808 | Ames 35337 |

Collectors' original notes indicates wild origin. "There are some questions about this accession's identity that may require further work to answer. According to the Flora of the USSR, Salix oxica (a synonym of S. excelsa per GRIN) is only found naturally on shores in Central Asia. It may be escaped from cultivation in Georgia, imperfectly documented with respect to its native range, or possibly this accession is misidentified. The Salix ICRA seems to regard this as possibly the same as Salix alba 'Vitellina'/S. alba var. vitellina, although that is generally a single clone in cultivation. The origins of that cultivar have never been clearly understood, but it was speculated to have originated in a fairly southern region" (Stefan B. Lura, National Arboretum Botanist, pers. comm. 27 November 2019). Based on Skvortsov (1999), defining limits of S. excelsa natural range is even more complicated a task than doing it for S. alba, as S. excelsa was widely cultivated since ancient times. S. excelsa is cultivated on the territory extending from Israel and Syria to Kashgaria, Kashmir, and western Gansu. In the Elburz Mountains, it ascends to 2,500m; in Middle Asia, to 2,00m (in the Darvaz and western Pamirs, to 2,200 M0; to 2,800 m around Kabul. Numerous intermediate forms are found in the areas where S. excelsa is cultivated within the range of S. alba and particularly where both willows have been cultivated for a long time, such as Syria, eastern Asia Minor, central and eastern Transcaucasia, and partially Middle Asia. These forms, which are difficult to identify appear to be hybrids. | 2097806 | Ames 35254 |

High with peat and organic matter | Wild material | Salix candida is a boreal species with a concentrated abundance and distribution in the northern tier of the U.S., including Alaska, and in Canada from Newfoundland to British Columbia (Decker 2006). Occurrences in South Dakota are rare and disjunct and known only to occur in seven sites (Decker 2006) in five counties including: northeast South Dakota - Roberts (2), Day (2), Deuel (1), Grant (1) and western South Dakota - Pennington (1) where all except the Pennington County site are represented by only one or a few genets. The McIntosh Fen supports the largest population of S. candida in the state estimated at a couple hundred genets. Plants measured (2019) approximately 5-6' in height with heavily pubescent leaves and stems. This population of S. candida at this site located along Castle Creek was initially documented by Arthur C. McIntosh (1930) in 1924 and 1925 as vouchers No. A57 and No. 729, respectively. Interestingly in 1962, S. G. Froiland published 'The genus Salix (Willows) of the Black Hills of South Dakota" and specifically referred to the correct identification of McIntosh's S. candida vouchers. However, S. candida was not relocated despite Froiland's efforts in the 1950's noting "all areas from which they were reported were covered thoroughly". Froiland (1962) indicated "S. candida was present in the Black Hills in the past, but apparently is no longer present". To date (2020), this population is in stable condition, but localized to only a few (2-3) acres. | 2097750 | Ames 35214 |

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 (Salix petiolaris Native Distribution from Elbert Little's "Atlas of United States Trees") covers mostly the northeastern US stretching from Maine to western North Dakota and Canada south to central Iowa. This accession would represent genetics from the south, southwestern edge of the species native range. 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. Plants of this accession, 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 |

Their only accession of the species (AA 432-62) also came from Botanical Gardens and Arboretum, 613 00 Brno, Czechoslovakia, sent by I.J. Chmelar. The cultivar is a male clone and distinguished from other selections by having dark reddish brown year-old (coppiced) wood instead of bright green stems; the yellow male catkins of 'Arnold Select' are showy. -SBL | 2145039 | NA 44004 |

Survival, height, spread, canopy width, and canopy density data were recorded. Riverbend Germplasm silky willow was selected for its excellent canopy density, growth, and overall appearance. It represents an unaltered selection of naturally occurring germplasm (Indiana source). This male clone is a tall, erect, multi-branched, native N. American shrub that grows to 3.5 meters tall and responds well to coppicing. Thick canopy of lanceolate, fine-toothed leaves that grow to 12.5 cm long and are dark green and smooth above, and glaucous (white) and sericeous (silky) beneath. Twigs are hairless, light green to brown in color and brittle at the base. Intended for use in streambank/shoreline restoration and riparian corridors. | 1684141 | Ames 27796 |

Original planting stock collected from the Morton Arboretum, Lisle, Illinois. Planting stock was sent to Coffeeville, Mississippi in 1963 via National Plant Materials Center, Beltsville, Maryland. Large, upright, multi-branched shrub to 4 m. Branches glabrous, yellowish gray; branchlets slender, glabrous, very flexible, pale green and yellowish under the bark. Leaves opposite or alternate, linear to lanceolate, 5-10 cm long, 5-12 mm wide, faintly serrate, apex acuminate, base rounded or obtuse, pale pink and brown when young, glabrous bright green above and glaucous beneath when mature, with numerous lateral viens. Male catkins cylindrical, densely flowered, 2-3 cm long, sessile with hairy, obovate flower scales, staminal filaments connate, anthers purple at emergence becoming red, orange, and yellow progressively. Female catkins 2-3.5 cm long, subsessile, densely flowered, scales long-hairy, ovary sessile, densely pubescent, style and stigma short, bifid. Uses include stream bank erosion control, plant diversity in riparian buffer plantings, urban conservation as an ornamental shrub and as a source of plant material for making baskets. It can also provide food, cover, and nesting sites for wildlife. Appears to be resistant to canker diseases. Prefers moist soil areas with good fertility. Anticipated area of adaptation would be plant hardiness zones 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b. | 1631958 | Ames 26605 |
