Sugarberry Plant Fact Sheet
Plant Fact Sheet Wildlife: Many species of songbirds including SUGARBERRY mockingbirds and robins eat the fruit and use the tree for nesting habitat. It is a larval and nectar host for two Celtis laevigata Willd. butterflies: hackberry emperor (Asterocampa celtis) and Plant Symbol = CELA American snout (Libytheana carineta). White-tailed deer browse the leaves and fruit. Contributed by: USDA NRCS Plant Materials Program Other Uses: Sugarberry is used for furniture, athletic goods, firewood, and plywood. It has limited use for flooring, creating, and for wood posts. It is used as an ornamental and as a street tree in residential areas in the lower South Status Please consult the PLANTS Web site and your State Department of Natural Resources for this plant’s current status (e.g. threatened or endangered species, state noxious status, and wetland indicator values). Description and Adaptation Sugarberry is a native tree that can grow up to 80 feet in height and up to 3 feet in diameter. It is a short lived tree, probably living not more than 150 years. It has a broad crown formed by spreading branches that are often drooped. The bark is light gray in color and can be smooth or covered with corky warts. The branchlets are covered with short hairs at first and eventually they become smooth. The leaves are alternated, simple, and slightly serrate. The leaves are 2-4 inches long and 1 to 2 Robert H.

Polyploidy in Trema (Ulmaceae)
1971 341 Polyploidy in Trema (Ulmaceae) A. S. Hans1,2,3 Panjab University, Botany Department, Chandigarh 14, India ReceivedDecember 18, 1969 Introduction Trema Lour. belongs to Ulmaceae, a small family of trees and shrubs, encompassing 15 genera and about 150 species (Lawrence 1951) in tropics and subtropics of both the hemispheres. Trema is a small genus composed of 30 tropical species of which only three species constitute the Indian flora. The members of the Ulmaceae show variation in basic chromosome number. Celtis is polybasic with x=10, 11, and 14 (Darlington and Wylie 1955), while Ulmus, Holoptelea and Zelkovia exhibit a uniform base number of 14. A few instances of inter and intraspecific polyploidy in Celtis and Ulmus exist in nature. Celtis australias has been reported to be a tetraploid (2n=40), while C. laevigata, C. sinensis, and C. occidentalis are diploid, all with 2n=20 (Bowden 1945). The report of 2n=28 in C. occidentalis (Sax 1933) is suggestive of aneuploid races in the species. Most of the species of Ulmus are diploid except U. americana where in addition to the diploid race (Krause 1930), a tetraploid race is also known (Sax 1933). Artificial triploids and tetraploids have been raised in U. glabra by Ehrenberg (1945). The two chromosomally known species of Trema exhibit variable numbers. T. orientalis has been reported to have n=18 (Arora 1960) from Banglore and n=20 (Gajapathy 1961) from Madras in South India; T. politoria has n=10+B (Mehra and Gill). In view of the discordant reports on the chromosome number (n=18, 20) in Trema orientalis, the cytological study was undertaken to ratify the chromosome number, to assess the incidence of polyploidy, and if possible to determine the base number of this small genus.

Hackberry/Sugarberry FNR-284-W Daniel L
PURDUE EXTENSION Hardwood Lumber and Veneer Series Hackberry/Sugarberry FNR-284-W Daniel L. Cassens, Professor and Extension Wood Products Specialist Department of Forestry and Natural Resources, Purdue University, West Lafayette, IN 47907 This lumber group is composed of two species that cannot be separated once they are processed into lumber or veneer. Hackberry (Celtis occidentalis L.) ranges from the Great Plaines to the east coast and from the Great Lakes states to central Tennessee and Arkansas. It is easily recognized by its very warty bark. Hackberry prefers moist, well-drained soil but will grow on limestone outcrops and other droughty areas. It is usually a scattered tree in the forest or more concentrated in old fence rows and at the edge of woods. Sugarberry (Celtis laevigata Willd.) is the southern counterpart to hackberry. It ranges from Virginia to southern Florida and west to the Rio Grande and north to southern Illinois and Indiana. Sugarberry is a southern bottomland species, and the bark is less warty. Both species are medium sized trees 60 to 80 feet tall and 18 inches to 4 feet in diameter. The largest hackberry reported is 6.6 feet in diameter and the largest sugarberry is 8.5 feet in diameter at 4½ feet above the ground. Wood Color and Texture The sapwood is usually a very light yellowish green and wide in healthy trees. A variegated brown wood can develop in the heart and around dead branch stubs. Chip Morrison Dark streaks of mineral are common. As a white Hackberry tree sapwood species, the wood develops both fungal and oxidation stains very quickly in warm weather.

Landscaping Near Black Walnut Trees
Selecting juglone-tolerant plants Landscaping Near Black Walnut Trees Black walnut trees (Juglans nigra) can be very attractive in the home landscape when grown as shade trees, reaching a potential height of 100 feet. The walnuts they produce are a food source for squirrels, other wildlife and people as well. However, whether a black walnut tree already exists on your property or you are considering planting one, be aware that black walnuts produce juglone. This is a natural but toxic chemical they produce to reduce competition for resources from other plants. This natural self-defense mechanism can be harmful to nearby plants causing “walnut wilt.” Having a walnut tree in your landscape, however, certainly does not mean the landscape will be barren. Not all plants are sensitive to juglone. Many trees, vines, shrubs, ground covers, annuals and perennials will grow and even thrive in close proximity to a walnut tree. Production and Effect of Juglone Toxicity Juglone, which occurs in all parts of the black walnut tree, can affect other plants by several means: Stems Through root contact Leaves Through leakage or decay in the soil Through falling and decaying leaves When rain leaches and drips juglone from leaves Nuts and hulls and branches onto plants below. Juglone is most concentrated in the buds, nut hulls and All parts of the black walnut tree produce roots and, to a lesser degree, in leaves and stems. Plants toxic juglone to varying degrees. located beneath the canopy of walnut trees are most at risk. In general, the toxic zone around a mature walnut tree is within 50 to 60 feet of the trunk, but can extend to 80 feet.

Woody and Herbaceous Plants Native to Haiti for Use in Miami-Dade Landscapes1
Woody and Herbaceous Plants Native to Haiti For use in Miami-Dade Landscapes1 Haiti occupies the western one third of the island of Hispaniola with the Dominican Republic the remainder. Of all the islands within the Caribbean basin Hispaniola possesses the most varied flora after that of Cuba. The plants contained in this review have been recorded as native to Haiti, though some may now have been extirpated due in large part to severe deforestation. Less than 1.5% of the country’s original tree-cover remains. Haiti’s future is critically tied to re- forestation; loss of tree cover has been so profound that exotic fast growing trees, rather than native species, are being used to halt soil erosion and lessen the risk of mudslides. For more information concerning Haiti’s ecological plight consult references at the end of this document. For present purposes all of the trees listed below are native to Haiti, which is why non-natives such as mango (the most widely planted tree) and other important trees such as citrus, kassod tree (Senna siamea) and lead tree (Leucanea leucocephala) are not included. The latter two trees are among the fast growing species used for re-forestation. The Smithsonian National Museum of Natural History’s Flora of the West Indies was an invaluable tool in assessing the range of plants native to Haiti. Not surprisingly many of the listed trees and shrubs 1 John McLaughlin Ph.D. U.F./Miami-Dade County Extension Office, Homestead, FL 33030 Page | 1 are found in other parts of the Caribbean with some also native to South Florida.
