Notes on Fraxinus Profunda (Oleaceae)
Nesom, G.L. 2010. Notes on Fraxinus profunda (Oleaceae). Phytoneuron 2010-32: 1–6. Mailed 10 August 2010. NOTES ON FRAXINUS PROFUNDA (OLEACEAE) Guy L. Nesom 2925 Hartwood Drive Fort Worth, TX 76109, USA www.guynesom.com ABSTRACT A taxonomic overview is provided for Fraxinus profunda –– including a nomenclatural summary with lectotypes designated for F. profunda and the synonymous F. michauxii , an updated morphological description including a comparison with F. pennsylvanica , and a county-level distribution map. Geographically disjunct records for F. profunda in distinctly inland localities (Mississippi and Alabama) are documented; far-inland records from Tennessee and North Carolina were based on collections of F. biltmoreana . KEY WORDS : Fraxinus profunda , F. michauxii , F. pennsylvanica , Oleaceae Fraxinus profunda occurs primarily along the Atlantic and Gulf coasts into peninsular Florida and in drainages of the Mississippi River and in the Ohio River basin (Little 1977; McCormac et al. 1995). At the northwestern corner of its range, it occurs in bottomlands of the Kankakee River (vPlants 2010), an Illinois/Mississippi River tributary. Limits of the northern range of the species (Michigan, Ontario) have recently been documented in detail (McCormac et al. 1995; Waldron et al. 1996). The trees consistently grow in river swamps and floodplains, especially those seasonally inundated, freshwater tidal wetlands, commonly with bald cypress, swamp cottonwood, and water tupelo. In Illinois, Indiana, Ohio, and northward, they often are found in wet woods and swampy depressions in upland woods as well as till plains and clay lake plains of post-glacial lake beds. Based on the map from Little (1977), Harms (1990) noted that the range of Fraxinus profunda is “quite discontinuous,” but addition of recent records shows a more continuous range (Fig. -

Cytogenetics of Fraxinus Mandshurica and F. Quadrangulata: Ploidy Determination and Rdna Analysis
Tree Genetics & Genomes (2020) 16:26 https://doi.org/10.1007/s11295-020-1418-6 ORIGINAL ARTICLE Cytogenetics of Fraxinus mandshurica and F. quadrangulata: ploidy determination and rDNA analysis Nurul Islam-Faridi1,2 & Mary E. Mason3 & Jennifer L. Koch4 & C. Dana Nelson5,6 Received: 22 July 2019 /Revised: 1 January 2020 /Accepted: 16 January 2020 # The Author(s) 2020 Abstract Ashes (Fraxinus spp.) are important hardwood tree species in rural, suburban, and urban forests of the eastern USA. Unfortunately, emerald ash borer (EAB, Agrilus planipennis) an invasive insect pest that was accidentally imported from Asia in the late 1980s–early 1990s is destroying them at an alarming rate. All North American ashes are highly susceptible to EAB, although blue ash (F. quadrangulata) may have some inherent attributes that provide it some protection. In contrast Manchurian ash (F. mandshurica) is relatively resistant to EAB having coevolved with the insect pest in its native range in Asia. Given its level of resistance, Manchurian ash has been considered for use in interspecies breeding programs designed to transfer resistance to susceptible North American ash species. One prerequisite for successful interspecies breeding is consistency in chromosome ploidy level and number between the candidate species. In the current study, we cytologically determined that both Manchurian ash and blue ash are diploids (2n) and have the same number of chromosomes (2n =2x = 46). We also characterized these species’ ribosomal gene families (45S and 5S rDNA) using fluorescence in situ hybridization (FISH). Both Manchurian and blue ash showed two 45S rDNA and one 5S rDNA sites, but blue ash appears to have an additional site of 45S rDNA. -

E. Mason • 3 1 T. M. Poland • K. S. Knight Received: 1 December 2014 / Accepted: 10 June 2015 / Published online: 21 June 2015 Ó Springer Science+Business Media Dordrecht (outside the USA) 2015 Abstract The emerald ash borer (EAB; Agrilus planipennis Fairmaire) is a bark and wood boring beetle native to east Asia that was first discovered in North America in 2002. Since then, entire stands of highly susceptible green ash (Fraxinus pennsylvanica Mar- shall) have been killed within a few years of infestation. We have identified a small number of mature green ash trees which have been attacked by EAB, yet survived the peak EAB infestation that resulted in mortality of the rest of the ash cohort. Adult landing and feeding preference bioassays, leaf volatile quantification and EAB egg bioassay experiments were used to characterize potential differences in responses of these select ‘‘lingering’’ green ash trees relative to known EAB susceptible controls. Three selections were identified as being significantly less preferred for adult feeding, but no specific leaf volatile profile was associated with this reduced preference. Egg bioassays identified two ash selections that had significant differences in larval survival and development; one having a higher number of larvae killed by apparent host tree defenses and the other having lower larval weight. Correlation and validation of the bioassay results in replicated plantings to assess EAB resistance in the field is still necessary. -

Ash FNR-272-W Daniel L
PURDUE EXTENSION Hardwood Lumber and Veneer Series Ash FNR-272-W Daniel L. Cassens, Professor and Extension Wood Products Specialist Department of Forestry and Natural Resources, Purdue University, West Lafayette, IN 47907 Ash refers to a group of five species ranging throughout the eastern United States. White ash is the best known and preferred species. Technically, only wood from the black ash tree can be separated from the other species, and it is sometimes sold separately and referred to as brown ash by lumbermen. White ash ranges from the Great Plains east and from southern Canada south, with the exception of the lower Mississippi River Delta and coastal plains area. The tree prefers deep, moist, fertile upland soils and is usually a scattered tree associated with many other species. The largest tree reported is over 8 feet in diameter at 4½ feet above the ground. Black ash ranges from southeastern Canada through the northern half of the eastern United States. It prefers moist areas. The largest tree reported is over 4 feet in diameter at 4½ feet above the ground. Green ash and pumpkin ash may be abundant on certain sites. Blue ash is normally a scattered tree. The lumber from these species is generally mixed with white ash and sold together. A lighter, soft- textured pumpkin ash, more common in the south, Chip Morrison Dan Cassens and white ash is sometimes sold separately. Wood Color and Texture Both color and texture vary substantially in ash Most ash in the Appalachian and southern region lumber. The earlywood pores are large and abruptly is fast growth. -
