Netleaf Hackberry Celtis Reticulata Torr Netleaf Hackberry Celtis reticulata Torr. Ulmaceae Species description Netleaf hackberry is a native tree that may grow 35 feet tall with a crown of equal measurement in diameter. The trees generally occur from 2,500- 6,000 feet in elevation, and may be hardy to -20ºF. Hackberry trunks are well developed, with knobby, irregular growth forms on the trunks and branches, creating a strange, erratic shape to the trees, though this quality tends to diminish farther south in Mexico. The bark is dark grey and deeply furrowed on the lower trunks and lighter gray on the branches. Hackberry leaves are alternate with smooth margins, though they may be occasionally toothed near the leaf base. The leaves are slightly heart-shaped, rough in texture and dark green. Where the leaf connects to the stem, one side is often larger. Inconspicuous, small, greenish flowers appear in March and April as new leaves emerge. The fruit are orange red, sweet, edible, and spherical (drupes), about 1/4 to 3/8 inch in diameter, and contain one seed. The fruits persist through the winter. Hackberry trees may live for 100-200 years. Natural and cultural history Netleaf hackberry is native to the western United States and northern Mexico. Hackberry trees often grow as an over-story dominant in riparian woodlands. They usually occur in moist soil, along streams, canyons, and washes, on plains grassland, and in the upper desert, desert grasslands, and woodland zones. Planting considerations and propagation techniques The species prefers deep, well-drained, loamy soils. Netleaf hackberry grows best in full sun, but also does well in partial shade. The trees are wind pollinated. Seed propagation of netleaf hackberry requires cold treatment; the seeds can be stratified at 41ºF for 120 days in moist sand. The trees can also be reproduced through vegetative cuttings. Water needs Netleaf hackberry trees are fairly drought tolerant, especially upon maturity. Care The trees have irregular growth patterns and the abrupt branches may feel sharp and difficult to work around. The trees generally do not need pruning except to shape to fit a desired space. Harvesting and processing The faintly sweet, thin-fleshed berries may be eaten raw, made into preserves, or used as a seasoning for meat. The berries do not have much flesh, though and are more important as a food resource for birds and wildlife. References and resources Bonner, F. T. 1974. Celtis L.

  • Climate Ready Trees for Central Valley Communities
    The goal of this study is to evaluate the survival and growth of seldom used but promising trees in the Central Valley. We can create more resilient Climate Ready Trees for urban forests by shifting the palate of trees planted to those proven to Central Valley Communities perform best when exposed to climate stressors such as heat, drought, high winds, pests, disease and soil salinity. 1. Mulga (Acacia aneura) Mulga is native to arid Western Australia and tolerates hot and dry conditions. It can grow in sandy, loam, or clay soil types. This versatile and hardy tree produces ascending thornless branches and grows 15 to 20 feet in height. The evergreen foliage is gray-green and the tree has yellow flowers in the spring. Maintain leader to avoid suckering. 2. Netleaf Hackberry (Celtis reticulata) The Netleaf Hackberry is native to riparian areas in the Southwest. A deciduous tree, it reaches heights of 25 to 35 feet with a spreading or weeping canopy. The ovate leaves are medium green and turn yellow in the fall. The flowers mature into red drupes that attract birds. The Netleaf Hackberry is drought tolerant and able to thrive in variety of soil types. 3. Desert Willow (Chilopsis linearis ‘Bubba’) The Desert Willow is a small flowering desert tree native to California and the Southwest. The cultivar Bubba can reach 25 to 30 feet with a spread of 20 to 25 feet. It has profuse, long- lasting blooms. The showy flowers are pink and white. Leaves are linear blue green and turn golden in the fall.

    Macfarlane's four o'clock (Mirabilis macfarlanei) ENDANGERED Flowers (left), habit (center), and habitat (right) of Macfarlane’s four o’clock. Photos by Thomas Kaye. If downloading images from this website, please credit the photographer. Family Nyctaginaceae Plant description Macfarlane’s four o’clock is a stout perennial that forms hemispheric clumps 0.6-1.2 m in diameter, with several freely branched decumbent or ascending stems that are glabrous to sparsely puberulent. The leaves are opposite and fleshy, the lower blades orbicular to ovate-deltoid, the upper narrowly ovate. The petioles of lower leaves are 1- 2.5 cm long; upper leaves are nearly sessile. Flowers are clustered (4-7) in involucres borne on stalks about 1 cm long in the upper axils and on shoot apices. The conspicuous involucres are green to purplish, 1.3-2.5 cm long. The showy perianth is magenta, broadly funnelform, and 1.5-2.5 cm long, the limb slightly longer than the tube. The ellipsoid fruits are light brown to grayish, with 10 slender ribs visible when wet, 6-9 mm long, tuberculate, glabrous or very sparsely puberulent. Distinguishing characteristics No other Mirabilis species occur within the range of Macfarlane’s four o’clock. Mirabilis laevis var. retrorsa has shorter involucres (0.5-0.7 cm long), a white to pale pink perianth, and ranges from Malheur and Harney Counties in Oregon southward. Macfarlane’s four o’clock is most closely related to M. multiflora var. glandulosa and M. greenei, which occur in Nevada and California, respectively, and have longer involucres and larger perianths.

When selecting appropriate species, the following should be considered: Mature size and space available Plant characteristics (form, allergens, fragrance, color) Maintenance requirements (ease of care, litter) Plant tolerances to site characteristics (heat, air pollution, soil compaction) Functional uses (shading, screening, erosion control, safety) Suitability (streets, electric lines, pedestrian traffic, drought conditions) All of plants in this document are listed in and comply with the Arizona Department of Water Resources Low Water Use/Drought Tolerant Plant List (find the complete list of plants at www.azwater.gov/azdwr/WaterManagement/ AMAs/documents/LWU_Plants1.pdf). Only those plants on this list are allowed on Mesa public right-of-ways. However, this does not imply that every plant listed is suited to every right-of-way or low water use landscape situation.

  • The Genetic Structure of Celtis Tenuifolia and Comparisons to the Related Species C
    The genetic structure of Celtis tenuifolia and comparisons to the related species C. occidentalis, and C. laevigata: Implications for the conservation management of threatened populations in Southern Ontario by Andrew Hayes A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements of the degree of Master of Science in Biology Carleton University Ottawa, Ontario © 2019, Andrew Hayes Abstract Celtis tenuifolia is a threatened shrub species in southern Ontario which co-occurs with Celtis occidentalis and Celtis laevigata across the eastern United States. Although it is quite common further south, only six disjunct sites in Ontario currently exist, and these fragmented populations are susceptible to extinction due to habitat loss caused by quarrying operations, sand pit expansion, and beetle infestations. It is difficult for conservation managers to distinguish the three related Celtis species morphologically, and taxonomists have questioned the species limits in this group. Using microsatellite markers and flow cytometry, we assessed the relationship between genetic diversity, ploidy, and morphology in this group. We have determined that C. tenuifolia is an apomictic triploid with hybrid origins, and flow cytometry provides a reliable tool for distinguishing it from the sexual diploids C. occidentalis and C. laevigata. Furthermore, the same C. tenuifolia genotypes occur in a variety of ecological settings, demonstrating remarkable phenotypic plasticity. The results of these assessments will provide direction to the conservation management of Celtis tenuifolia, specifically providing field workers with reliable identification of the plant, as well as resolving concerns around hybridization and the risks of inbreeding and outbreeding depression. ii Acknowledgements I would first like to thank my supervisor, Tyler Smith, for his support, guidance and patience throughout this project.
