Presentation Transcript

  1. Horse Chestnut • large, 7-leaflet, palmately-compound leaves • leaves have impressed veins • fruits are the most spiny of all Aesculus • each leaflet is 4" to 10" long and obovate with an acuminate tip

  2. commonly 50' to 75' tall, but 100' specimens are possible • Bark exfoliates in plates on older branches and the trunk to reveal showy orange bark underneath most of the bark is dark gray and brown • Fruit 2" to 2.5" diameter capsules with 1 or 2 seeds

  3. Ironwood • Males in persistent ½ to 1 inch catkins, in clusters of 3 (resembling a bird's toes); females in slender, light green ½ inch catkins, appearing in spring. • Alternate, simple, 2 to 4 inches, oblong with narrowed tips and doubly toothed edges.

  4. Light brown to reddish-brown, finely divided into thin scales that peel away from the trunk, as if shredded by a cat's claws. • Mature Size: 20 to 30 feet in height and 7 to 10 inches in diameter.

  5. Japanese Knotweed • Height - Individual stems are 3-9 feet tall depending on the vigor of the colony. 
Stem - The hollow, bamboo-like stems are erect and unbranched or with a few branches toward the tip.

  6. Leaves - Leaves are alternate on the stem, simple, 4-6 inches long and almost as wide, and dark green. Japanese knotweed leaves are abruptly squared-off (truncate) at the base

  7. Japanese Larch • Needles: Deciduous, appearing singly on new growth and in whorls on older growth, 1 to 1 1/4 inches long, green to glaucous blue-green in color.

  8. Bark: On young trees the bark is scaly and gray, later becoming furrowed with a reddish brown inner bark. • Form: Well formed, with a straight stem and pyramidal crown. Lateral branches commonly droop.

  9. Black Locust • Black Locust is a medium-sized tree, growing up to 80 feet tall. It is easily recognized by its leaves and paired spines up to ½ inch long • leaves of this tree are pinnately compound, with (7-19) leaflets on one main stem. Leaflets are always paired, except for the one on the end of the leaf. Leaf color is bluish-green on top, and pale underneath. The entire leaf is 6 to 12 inches long. Leaflets are oval-shaped and less than 2 inches long with no teeth and a bristle tip.

  10. Black Locust bark is light gray with deep furrows. Spines grow on twigs, close to where the leaves are attached. They are always in pairs. • Locust fruits are pods, and Black Locust has dark brown pods up to 4 inches long.

  11. Honey Locust • Leaf: Alternate, pinnately compound, 5 to 8 inches long, with 15 to 30 leaflets or bipinnately compound with 4 to 7 pairs of minor leaflets. Leaflets are 1/2 to 1 1/2 inches long, ovate to elliptical in shape, green to yellow-green. • A very distinctive, 6 to 8 inches long, flattened, red-brown, leathery pod that becomes dry and twisted

  12. Bark: Initially, gray-brown to bronze, and smooth with many horizontal lenticels, later breaking into long, narrow, curling plates. Often displaying clusters of large, branched thorns on trunk. • Form: A medium size tree with a typically short bole and an airy, spreading crown, reaches up to 80 feet tall.

  13. Ash-Leafed Maple (Box Elder) • Leaves – pinnately compound and opposite, usually 5 leaflets; often resembles poision ivy, which has alternate, pinnately (3 leaflets) compound leaves. • Twigs - moderate to very stout, smooth and covered with a waxy film giving the twig a shiny green to purple color.

  14. Bark - smooth on younger trees but soon developing narrow ridges and shallow furrows. Ridges and furrows are interlacing. Bark on mature trees is dark brown. • Boxelder grows commonly along the banks of streams and rivers, and may occur as a weedy species

  15. Norway Sugar Red

  16. Norway Maple • Leaves: paired, deciduous, dark green, palmate (like a hand), broader across than from base to tip, marginal teeth with long hair-like tips. • samaras” joined broadly at nearly 180° angle; milky sap will ooze from cut veins or petiole.

  17. up to 90 ft. in height with broadly-rounded crown; bark is smooth at first but becomes black, ridged and furrowed with age; milky sap.

  18. Red Maple • opposite, 2" to 4" long, 3 or 5-lobed • medium green upper leaf color, gray-green or frosty underside • Red maple grows in wet or moist soils on river banks and in swamps along with other hardwoods such as cottonwoods, oaks, black ash, and black tupelo but may also be found in uplands and dry ridges.

  19. Red Maple • becomes more spreading with age, eventually developing a more or less rounded or oval outline • a medium to large tree, 40' to 70' tall, but can be over 100' tall • ashy-gray bark

  20. Sugar Maple • Leaf: Opposite, simple and palmately veined, 3 to 6 inches long, 5 delicately rounded lobes, entire margin; green above, paler below • Fruit: Two-winged horseshoe-shaped samaras about 1 inch long, appearing in clusters, brown when mature in in the fall.

  21. Bark: Variable, but generally brown, on older trees it becomes darker, develops furrows, with long, thick irregular curling outward, firm ridges. • Form: Medium to tall tree (to 100 feet) with very dense elliptical crown.
