| 2 | Ames 35261 | Separation from Ames 23752 | Quercus ×beckyae Gaynor | Iowa, United States | |  | Historic | 2019 | DEVELOPED | 04/26/2014 | | | | | Clone | First generation hybrid arising from Quercus prinoides (Ames 23752) x Quercus macrocarpa (OP). Multi-stemmed shrub-like growth habit characteristic of Q. prinoides with acorns with some fringe-like protuberances on the cup characteristic of Q. macrocarpa. Leaves intermediate in size between typical Q. macrocarpa and Q. prinoides, while overall leaf morphology is more characteristic of Q. macrocarpa. After five years of growth in the field in central Iowa, specimen measured 6' in height and 7' in width. The exact paternal identity is unknown. Maternal genetics are Ames 23752, originally collected in Richardson County Nebraska (T1N R15E NW 1/4 NW 1/4 Sec. 21) in 2006 by Jeffrey D. Carstens (USDA-ARS, NCRPIS) and Bob Henrickson (Nebraska Statewide Arboretum). Seedlings from the original 2006 collection were planted at Ames, Iowa at the North Central Regional Plant Introduction Station (NCRPIS) with acorns harvested in 2014. A total of 100 seedlings from the 2014 harvest were planted to the field in 2015. In 2019, one specimen was identified as a hybrid. Quercus × beckyae Gaynor (Q. macrocarpa Michx. × Q. prinoides Willd.) was originally described by Bruce D. Gaynor and named after Rebecca J. Hale (Gaynor 1987). The holotype for Q. × beckyae is held at MICH (Gaynor 81B21). Currently (J.D. Carstens, personal communication, 2 January 2020), no other clones of this hybrid combination exist in cultivation. This accession may be well suited for the home landscape due to its small stature and ability to tolerate a wide range of soil types. | 2098632 | Ames 35261 |

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. | 1831352 | Ames 30493 |

T85N R23W W 1/2 of Sec. 19 Story City Quad; T84N R24W NW 1/4 of Sec. 7 and T84N R23W SE 1/4 of Sec. 12 Ames East Quad, Story County | 42.10222222, -93.57944444 | 280 | Floodplain/bottomland forest. | Wild material | In 2012, a total of 59 mature specimens (d.b.h. of approximately 12" or greater) of Gymnocladus dioicus were noted growing along a 5 mile linear stretch along the Skunk River with 37 specimens recorded as females and 22 recorded as non-fruiting. 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). The largest specimen of G. dioicus found in this area is approximately 90' in height and 40' in width and 35.5" in diameter. | 1749824 | Ames 29376 |
