Identification

This is a medium to large, moderately fast-growing, deciduous tree. In Minnesota mature trees are usually 40 to 60 tall and 10 in 16 in diameter at breast height. Large individuals can reach up to 75 in height and 56 in diameter. It is moderately long-lived, often reaching between 150 and 200 years in age. It has a deep, fibrous root system that, where conditions permit, may be10 to 20 feet deep. It has no taproot. It is usually found as scattered individuals in river terraces and floodplains, but it can persist when planted (by humans or birds) in dry upland areas.

The trunk is slender and usually divided near the base of the crown into a few large, upright, spreading limbs. On older trees the trunk is significantly flared at the base where it joins the surface roots. The branches are gracefully spreading and sometimes slightly drooping at the ends. Young trees have an oval crown. Older trees have a spreading, irregularly rounded crown.

The bark on young trees is thin, smooth, and light grayish-brown. It soon develops warty raised knobs, which develop into narrow, vertical, wavy, corky ridges as the tree ages. The wing-like ridges on otherwise smooth bark is a unique identifying feature of this tree. As the tree matures the ridges become flattened and more closely spaced and the bark becomes scaly.

First-year twigs are slender, slightly zigzagged, green becoming tinged with brown, and usually hairy. Second-year twigs are brown and hairless. Leaf scars are U-shaped to semicircular and have three dot-like bundle scars. The pith is white and is finely chambered, at least at the leaf nodes.

Lateral buds are reddish-brown, egg-shaped, flattened, pointed, ¼ to 5 16 long, and closely appressed to the twig. There is no true terminal bud, but the lateral bud at the end of the twig is often bent sideways.

The leaves are deciduous, alternate, and unlobed. They and are attached to the twig on a slender, hairy, ¼ to long leaf stalk. The blades are leathery, egg-shaped to lance-shaped, 2 to 4¾ long, and 13 16 to 2¼ wide. They taper gradually to a long, drawn out point at the tip with concave sides along the tip. The base is asymmetrical, rounded or somewhat heart-shaped. The upper surface is dark green and may be either mostly hairless or covered with short, straight hairs. The lower surface is pale green and hairy along the veins. The margins are toothed from the tip to well below the middle but not near the base. There are 10 to 40 sharp, forward pointing teeth per side. There are three main veins, one midrib and a pair of veins that originate just below the base of the blade, and 4 or 5 lateral veins per side that originate at at intervals along the midrib. The leaves turn light yellow in the fall.

Flowers appear in late April to late May. Male and female flowers are borne on the same first-year brachlet of the same tree. Male flowers appear on 1 16 to ¼ long stalks in small clusters at the base of the twig. Each male flower has 4 or 5 greenish or yellowish sepals, no petals, and 5 or 6 stamens on white filaments. Female flowers appear on to long stalks singly or in pairs in a leaf axil of the twig. Each female flower has 4 or 5 greenish or yellowish sepals, no petals, and 2 stigmas that are bent backward. The flowers are pollinated by the wind

The fruit is a fleshy, relatively dry drupe with a single pitted stone. It is spherical, ¼ to ½ in diameter, and is tipped with the remnants of the style. It is green at first, turning dull reddish-purple and often wrinkled at maturity. It matures in August to late September and remains on the tree until eaten by a bird.

Comments

Taxonomy
The genus Celtis was formerly placed in the family Ulmus (elms). A molecular phylogenetic study in 2002 caused a reordering of families in the order Rosales. As a result, this genus is now grouped with hemp and hops in the family Cannabaceae. The leading sources for taxonomic ranking, including ITIS37, NCBI34, GRIN38, and The Plant List36 reflect this change. Most botanical sources, including PLANTS3 and Flora of North America (FNA)45, do not.

How to identify hackberry tree. Wild edible berries are abundant, taste great, and are good for health.

Hackberry trees, Celtis occidentalis, can be found throughout most of North America. Close relatives of hackberry, such as sugarberry, Celtis laevigata, and Celtis australis can be found in other parts of North America and throughout the world.

The entire hackberry fruit is considered edible and can be ground as seasoning, made into hackberry milk, eaten raw as a whole food, or the thin sweet berry can be removed from the seed or nut and prepared into jams, jellies, fruit leather, etc.

Hackberries are high in protein, fat and carbohydrates, the three essential nutrients for survival, Hackberries are a great source of calcium, phosphorus and other micro-nutrients. Potentially a great winter survival super food, hackberries ripen in September and October lasting on the tree into winter, or even spring in some situations.

Hackberry is in the elm family, recently placed in the hemp family along with Cannabis, and has medicinal properties similar to that of other elm species. A hackberry bark decoction was used to treat sore throats and an extraction of the wood was used to treat venereal disease.

Hackberry wood is quite hard and was used for fencing and cheap furniture. Hackberry wood seems a bit springy to me, similar to hickory, and may possibly be used to make primitive bow staves.
