Described by Charles Sprague Sargent (first director for the Arnold Arborteum) as "heavy, hard, very strong and tough, closely grained, and susceptible of receiving a beautiful polish". Historically noted for a variety of uses in woodworking including furniture, heavy agricultural implements, timber frame buildings, pianos, hockey sticks, and hand tools. Ulmus thomasii is extremely drought tolerant, adaptable to very calcareous soils, and compared to U. americana or U. rubra has a very conservative growth rate requiring minimal attention in regards to pruning. Rock elm naturally tends to develop into a nice structural specimen in the landscape, unlike other fast growing cultivars in the nursery trade needing frequent attention. Rock elm has very fissured bark and is well known for maintaining a strong central leader resulting in a very attractive, pyramidal form. Despite many literature sources stating that "wings" on the stems are a key identifiying characteristic, this trait is not reliable and many genotypes may completely lack "wings" on the stems. While growth habit and morphology of dormant buds (very pointy) are good traits to help aid in identification, fruits are the best way to confirm identity. Fruits are densly pubescent, often described as "inflated" and generally reach maturity a couple weeks after Ulmus rubra and Ulmus americana. U. thomasii inflorescences are rather distinguishable from other Ulmus in being pendulous. Fruits are extremely prized treats for many birds, where fruits are often "robbed" prior to full maturity. Fruits are also highly prized by many other animals such as mice, squirrels, chipmunks, turkeys, etc. and are generally consumed within hours after fruit abscission. The native range of U. thomasii is concentrated in the northeastern United States and into Canada with disjunct populations documented in northwestern Missouri and northwestern Arkansas (Little, E. L. Jr. 1971). In the 1895 Silva of North America (vol. 7) it was stated that, “The value of the wood of the Rock Elm threatens its extinction and most of the large trees have already been cut.” Today, while rock elm is rather rare, especially in areas near the edges of its range, many states list the species as endangered or threatened warranting preservation efforts. Genetics of this accession would be representative of the species northwestern edge of its native range. Majority of specimens noted did not have characteristic "wings" on the stems and measured approximately 20" DBH or more with a few specimens nearing 30". Heights estimated between 70-90'. Rock elm in this area could be classified as locally abundant. 2167953Ames 36251

Charles Sprague Sargent (first director of the Arnold Arboretum of Harvard University, Boston, MA) described the wood of Rock Elm as "heavy, hard, very strong and tough, closely grained, and susceptible of receiving a beautiful polish".

Fruits are densly pubescent, often described as "inflated" and generally reach maturity a couple weeks after U. rubra and U. americana. U. thomasii flowering in central Iowa typically occurs the last week in April into the first week in May and are rather distinguishable from other Ulmus in being pendulous. Fruits are extremely prized treats for many birds, where fruits are often "robbed" prior to full maturity. Fruits are also highly prized by many other animals such as mice, squirrels, chipmunks, turkeys, etc. and are generally consumed within hours after fruit abscission. The native range of U. thomasii is concentrated in the northeastern United States and into Canada with disjunct populations documented in northwestern Missouri and northwestern Arkansas (Little, E.

Genetics of this accession would be representative of the species southwestern edge of its native range. At the collection site in nature (Ledges State Park), out of approximately 100 specimens noted only 1-2% of specimens had characteristic "wings" on the stems. Research was executed (Moore, P., 2024) involving the core sampling of U. thomasii and U. americana specimens in Ledges State Park to make growth ring widths and basal area increment comparisons. Results determined that the average age of cored trees U. thomasii (n=4) and U. americana (n=4) of both species was roughly 80 years, excluding the exceptional case of tree #007 (Ames 36073 23ncao02 SD). Tree #007 was aged at 300 years of age and currently (2025) ranks as the 14th largest U. thomasii in Iowa measuring 21" DBH with a height of 75' 5" and a spread of 43' 5" totalling 152.21 points (Rouw, M., personal communication, 4 May 2022). The computed mean density at 𝑀𝑀 = 12% for U. thomasii was 0.80 g/cm3, and for U. americana was 0.672 g/cm3. These values are both higher than the representative values inferred from the Woods Database which are 0.755 g/cm3 for U. thomasii and 0.56 g/cm3 for U. americana. To date, there is little to no information regarding U. thomasii resistance to Dutch Elm Disease. Collections of U. thomasii at the Arnold Arboretum have over-time succumbed to DED (Pruka, B., 2016). However, data recorded by Moore (2024) indicates that U. thomasii growing in central Iowa can surpass 300 years in age verifying it's long-term utilization in the landscape. 2142915Ames 36073

Ilex decidua can be in the low woods most of the way down to the river. Plant is a common understory shrub in the moist woodland habitat not far from the Sabine River. Soils: The underlying geology of this area is of Holocene origin and characterized as Alluvium. The alluvium and low terrace deposits along streams include sand, silt, clay, and gravel. Thickness is variable. In this case alluvium is from the Sabine River. (Source: USGS Texas Geologic Map Data). The primary soil types in the collection area are classified as Urbo and Mantachie soils. The Urbo series consists of deep, somewhat poorly drained soils. Permeability is very slow. These nearly level to gently sloping soils formed in clayey alluvium on flood plains of streams that drain uplands of the Southern Coastal Plain. Slopes range from 0 to 3 percent. In wet seasons late in winter and early in spring, the water table is at a depth of 1 to 2 feet and most areas of Urbo soils are subject to either occasional or frequent flooding of brief to long duration. The Mantachie series consists of very deep, somewhat poorly drained, moderately permeable soils on flood plains of the Southern Coastal Plain. They formed in loamy alluvium and considered acidic. Mantachie soils are subject to rare to frequent flooding in the winter and early spring for brief to long duration, unless protected. The seasonal high water table ranges from 1.0 to 1.5 feet of the surface during periods of high rainfall. (Source: NRCS Web Soil Survey).Wild material2139816NA 88509

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, -77.72242400287Plants are growing in part-shade to shade of a deciduous upland, very rocky, and dry forest community.

Historically and presently known for its extreme value as bow-wood and fence posts, Osage-orange represents one of the most widely planted tree species in the lower 48 US states as a living fence starting in the mid-1800's, in the late 1900's as a landscape tree for difficult sites, and most recently its chemical properties. Detailed history of Osage-orange and it's economic uses are well documented (Smith and Perino, 1981 and J. T. Winberry 1979). Osage wood is highly-prized for its use as fence posts (both living and non-living) and durable wood for wood working. Osage is an extremely drought and heat tolerant tree and is recommended for use in USDA cold-hardiness zones 5b or warmer. Although the species is commonly known for its stout thorns and large, globular fruits, the species is dioecious and the degree of thorns on individual genotypes can be extremely variable. This accession represents genetics collected from a naturalized population in central Iowa (Boone County - Harrison Township). Majority of specimens sampled averaged approximately 40-45’ in height with multiple (e.g. 1-5) trunks. The collection site represents a recognized Iowa Century Farm awarded in 1976 that was originally settled by Andrew Nelson and then purchased on 24 October 1874 for the amount of '9.00 per acre by Lester S. Carlson. According to Samuel Keith Carlson (grandson to Lester S. Carlson), in the 1930's-1940's there was a fence line plus a few additional specimens of significant size that were possibly planted by Lester S. Carlson in the 1870's or the previous owner during "hedge mania" in the 1850's. In the 1950's the original trees at the Carlson farm were removed, but the progeny have persisted throughout the woods and adjacent pasture areas and continue to spread. A corner fence post of Osage that was set in 1874 by Lester S. Carlson shortly after purchasing the property still remains (see image). Majority of the specimens in this population are nearly thornless or with relatively few thorns. Fruit sizes range between 70-90 mm in diameter with seed lengths ranging from 6.99 mm (min) to 11.68 mm (max) with the average length of 50 seeds at 9.36 mm. At time of collection (2 November 2022) approximately 20% of specimens were at peak, yellow fall color, while remaining specimens were still green/greenish-yellow. 2141741Ames 36028

Conservation assessments in North America indicate current (2026) and future concern for the species including Michigan (threatened); Massachusetts (endangered); Ontario Canada (endangered); with NatureServe's 2025 global G5 rank due to genetic swamping and habitat pressure. Red Mulberry seems to be extremely localized to moist, floodplain areas that are high-quality bottomland forests. This accession represents genetics collected from the northwestern edge of the species native range. Specimens sampled in nature displayed the following morphological characters: acuminate leaf tips, impressed veins, pubescent upper and lower leaves, flaky bark (often with tiny pin holes (insect emergence holes)), cordate leaf base, and umbrella-shaped growth habit.

Gentle slopes and wetlandsUncertain improvement statusThe native range for Osage-orange is reported from eastern Texas, southeastern Oklahoma, southwestern Arkansas, and the northwestern corner of Louisiana (Little, 1971). Historically and presently known for its extreme value as bow-wood and fence posts, Osage-orange represents one of the most widely planted tree species in the lower 48 US states as a living fence starting in the mid-1800's, in the late 1900's as a landscape tree for difficult sites, and most recently its chemical properties. Detailed history of Osage-orange and it's economic uses are well documented (Smith and Perino, 1981 and J. T. Winberry 1979). Osage wood is highly-prized for its use as fence posts (both living and non-living) and durable wood for wood working. Osage is an extremely drought and heat tolerant tree and is recommended for use in USDA cold-hardiness zones 5b or warmer. Although the species is commonly known for its stout thorns and large, globular fruits, the species is dioecious and the degree of thorns on individual genotypes can be extremely variable. This accession represents germplasm from a naturalizing, reproductive population collected in central Iowa (Polk County). Majority of specimens averaged approximately 40-50’ in height with multiple (e.g. 4-5) trunks. Specimens 03-1 and 03-2 were upright in form with tighter branch angles, while 03-10 was the widest spreading of all trees. Some yellow fall color (yellow) was apparent at time of fruit collection (10/05/2016). Size of fruits ranged from 9.00 to 10.75 inches circumference except for tree 03-5 with fruits averaging 7.33 inches circumference. 1942949Ames 33752

Rocky substrate. 20 degree northwest-facing slopeWild materialUlmus thomasii (Rock elm) is an underutilized tree species both in conservation and in the urban landscape. Charles Sprague Sargent (first director of the Arnold Arboretum of Harvard University, Boston, MA) described the wood of Rock Elm as "heavy, hard, very strong and tough, closely grained, and susceptible of receiving a beautiful polish". Historically noted for a variety of uses in woodworking including furniture, heavy agricultural implements, timber frame buildings, pianos, hockey sticks, and hand tools. U. thomasii is extremely drought tolerant, adaptable to very calcareous soils, and compared to U. americana or U. rubra has a very conservative growth rate requiring minimal attention in regards to pruning. Rock elm naturally tends to develop into a nice structural specimen in the landscape, unlike other fast growing U. americana cultivars in the nursery trade needing frequent attention. Rock elm has very fissured bark and is well known for maintaining a strong central leader resulting in a very attractive, pyramidal form. Despite many literature sources stating that "wings" on the stems are a key identifiying characteristic, this trait is not reliable and many genotypes may completely lack "wings" on the stems. While growth habit and morphology of dormant buds (very pointy) are good traits to help aid in identification, fruits are the best way to confirm identity. Fruits are densly pubescent, often described as "inflated" and generally reach maturity a couple weeks after U. rubra and U. americana. U. thomasii flowering in central Iowa typically occurs the last week in April into the first week in May and are rather distinguishable from other Ulmus in being pendulous. Fruits are extremely prized treats for many birds, where fruits are often "robbed" prior to full maturity. Fruits are also highly prized by many other animals such as mice, squirrels, chipmunks, turkeys, etc. and are generally consumed within hours after fruit abscission. The native range of U. thomasii is concentrated in the northeastern United States and into Canada with disjunct populations documented in northwestern Missouri and northwestern Arkansas (Little, E. L. Jr. 1971). In the 1895 Silva of North America (vol. 7) it was stated that, “The value of the wood of the Rock Elm threatens its extinction and most of the large trees have already been cut.” Today, since rock elm is rather rare, especially in areas near the edges of its range, many states list the species as endangered or threatened warranting preservation efforts. This accession represents genetics from northeast Iowa (Winneshiek County). In an assessment of some of the largest Ulmus thomasii (native and cultivated) across Iowa, four of the nine largest specimens in Iowa are present in Malanaphy Springs State Preserve where this accession was sampled. The second largest U. thomasii in the state located in Malanaphy Springs was measured on 22 May 2020 with a circumference of 6.42', height of 86.58', and an average crown spread of 68.00' (180 points) (Rouw, M., personal communication, 8 February 2021).1940580Ames 33357

Kentucky coffeetree is a picturesque shade tree that is extremely tolerant to highly alkaline and also slightly acidic soils, tolerant to both extreme drought and flood events, and has no serious insect or disease problems. These traits make G. dioicus a promising candidate among diverse tree genera to replace ash (Fraxinus) trees affected by the emerald ash borer (Agrilus planipennis) or oaks (Quercus) being affected by oak wilt (caused by the fungus Ceratocystis fagacearum) (Schmitz & Carstens 2017). Specimens at the collection site in nature averaged (n=7) 14.50” DBH and 53’ in height (Individual Tree measurements (DBH/Height): #1 = 13"/40', #2 = 15"/50', #3 = 14"/40', #4 = 15"/50', #5 = 13"/30', #6 = 16"/90', and #7 = 15"/70'). Sampling in 2010 estimated more than one hundred genetically distinct trees – the most coffeetrees noted in any single area observed throughout the species native range (Schmitz & Carstens 2018). A return site visit in 2016, estimated that three-quarters of the coffeetrees were dead or in decline after becoming overgrown by hops (Humulus sp.), a result of major flooding events in 2013 and 2014 where floods in 2013 persisted for nearly three months. Flood stage for this population of coffeetrees in the NW ¼ of Sec. 1 resides at 538 MSL (Mean Sea Level) which can be compared against data from the Mississippi River Lock and Dam 17 (Flood Events 2009-2024), where water levels were recorded 14' above ground level where multiple trees of Ames 30493 were sampled. 1831352Ames 30493

Considering that seed production was very poor in 2012, some specimens recorded as non-fruiting (potentially males) may actually be females. The SE 1/4 of Sec. 12 seemed to have a fair amount of G. dioicus regeneration with very small (6-24" tall) seedlings present along with an abundant number of Celtis occidentalis in the area of various sizes. Two very large (20-24" d.b.h. specimens of G. dioicus recently dropped to the ground, most likely the result of strong winds. This area also seems to represent two, distinctly different "clones" of males based on morphological branching structure. The SW 1/4 of Sec. 19 has an abundant population of Tilia americana that were significant in size (20-24" d.b.h. and approximately 70' in height).

Charles Sprague Sargent (first director of the Arnold Arboretum of Harvard University, Boston, MA) described the wood of Rock Elm as "heavy, hard, very strong and tough, closely grained, and susceptible of receiving a beautiful polish". Historically noted for a variety of uses in woodworking including furniture, heavy agricultural implements, timber frame buildings, pianos, hockey sticks, and hand tools. U. thomasii is extremely drought tolerant, adaptable to very calcareous soils, and compared to U. americana or U. rubra has a very conservative growth rate requiring minimal attention in regards to pruning. Rock elm naturally tends to develop into a nice structural specimen in the landscape, unlike other fast growing U. americana cultivars in the nursery trade needing frequent attention. Rock elm has very fissured bark and is well known for maintaining a strong central leader resulting in a very attractive, pyramidal form. Despite many literature sources stating that "wings" on the stems are a key identifiying characteristic, this trait is not reliable and many genotypes may completely lack "wings" on the stems. While growth habit and morphology of dormant buds (very pointy) are good traits to help aid in identification, fruits are the best way to confirm identity. Fruits are densly pubescent, often described as "inflated" and generally reach maturity a couple weeks after U. rubra and U. americana. U. thomasii inflorescences are rather distinguishable from other Ulmus in being pendulous. Fruits are extremely prized treats for many birds, where fruits are often "robbed" prior to full maturity. Fruits are also highly prized by many other animals such as mice, squirrels, chipmunks, turkeys, etc. and are generally consumed within hours after fruit abscission. The native range of U. thomasii is concentrated in the northeastern United States and into Canada with disjunct populations documented in northwestern Missouri and northwestern Arkansas (Little, E. L. Jr. 1971). In the 1895 Silva of North America (vol. 7) it was stated that, “The value of the wood of the Rock Elm threatens its extinction and most of the large trees have already been cut.” Today, since rock elm is rather rare, especially in areas near the edges of its range, many states list the species as endangered or threatened warranting preservation efforts. This accession was collected in northeast Nebraska (Dixon County) at Ponca State Park representing genetics from the extreme northwestern edge of the species native range and includes genetics (#775-6) from the current (2022) state champion. In an assessment of seedlings from all mother trees sampled (Carstens, J., personal communication, 12 April 2022), #775-4 produces the most vigorous seedlings which also consistently exhibited extremely corky/winged stems on new seedlings. Seedlings from other maternal lines show both winged and non-winged seedlings within the same maternal line and seedlings from some maternal lines have no wings. 1649925Ames 27341
