1Unit IV Kansas Plants: Trees, Shrubs and Woody Vines Information
2Trees, Shrubs and VinesEastern Kansas is the boundary between eastern deciduous forest and the tallgrass prairie.There are many different types of forest ecosystems, just as there are many different types of prairie ecosystems.The main forest community in eastern Kansas is the oak-hickory forest. These are the largest and most predominant trees here.We will focus here on trees that are very common in eastern Kansas, and that can also be found in riparian areas of western Kansas.Riparian is the forested area along streams and rivers.Western Kansas does not have many trees, but there is good riparian habitat along the waterways, and many of these trees can be found along the streams and rivers as you move west.
3Trees, cont.Tree identification: the easiest way is to look at the leaf. (the bark and overall height and shape are also valuable for identification)Leaf shapeOval, heart-shaped, oblong, lance-shaped, etc.Leaf margin (edge)Smooth, serrated (toothed), lobed, etc.Whether it is simple or compoundSimple, pinnately compound or palmately compound.Where the leaf attaches to the branch you will find a fatter part of the leaf stem called the “petiole”. Look for this petiole, and you will be able to tell where the actual leaf begins. On compound leaves, the entire structure from the petiole to the tip is one leaf, and each blade is called a “leaflet”. Leaflets do not have a petiole.
4Trees with simple leaves Simple leaf with serrated marginSimple leaf with lobesSimple leaf with smooth margin (edge)
5Trees with compound leaves Pinnately compound leaf—all leaflets are attached to a central shaft. (The leaf begins where my index finger is. This is the petiole attached to the branch).Palmately compound leaf—all leaflets are joined in center.Bi-pinnately (or double-pinnately) compound leaf—leaflets are pinnately compound and attached to a central shaft.
8Black Willow Long narrow serrated leaves Trunk usually leans instead of growing erect.Lives at edges of ponds and streams in KansasInner bark layer of willow trees contains salicylic acid, the original active ingredient in aspirin and where aspirin as a medication was derived from.Native Americans used to make a tea out of willow bark which they used for the same purposes that we use aspirin.
11Osage Orange Locally called the hedge-apple tree Produces the large, green hedge applesHas small thorns all over the branchesPlanted by people and bird/animal droppings along fences as a windbreak. People have planted this tree as a windbreak (hence the term hedge row) since the Dust Bowl era in order to help prevent wind erosion.
14MulberryNote the variation in leaf shape—some leaves are heart-shaped with serrated edges, and many leaves have one to several deep lobes. All leaves have a serrated edge.Flowers in May when the leaves emerge.Fruits in May and June, with a blackberry-type fruit that is red when immature and blackish purple when mature. They are very good to eat!Many animals eat the fruits of Mulberries.
16Elm sp.Several species of Elm trees occur in Kansas, and the American elm used to be the most common.Many American Elm trees died in this country in the last 50 years due to Dutch Elm disease, a fungal disease which was spread by elm bark beetles. American Elm trees are still getting sick and dying from this disease, and resistant hybrids are trying to be cultivated.Various species of Elm trees, along with remaining American Elms, can still be found throughout Kansas.
20Dogwood Smaller, under-story tree Grows in dense thickets along roadsides, streams, fences, woodland edgeExcellent for controlling erosionSlowly and carefully, split a leaf horizontally and you can slowly pull the two halves apart and you will see cottony fibers where the veins are. Only dogwoods do this.There are ornamental varieties of dogwoods because they have very pretty flowers and leaves turn nice colors in fall. Very hardy.
22Cottonwood Kansas State Tree Fast-growing tree and becomes massive Leaf is triangle-shaped and has a flat stem, and makes a lot of noise in the wind—sounds like rain.In June, the females of this tree produce the huge clouds of cotton fluff that you can see floating around in the wind. There are very small seeds attached to the fluff and this is how cottonwoods are dispersed.Turns a beautiful golden yellow in fall.
25Sycamore The sycamore has large, broad leaves with pointed lobes. Bark peels away to reveal the white trunk and branches.Has pendant fruit balls hanging off by October.One of the largest trees in Kansas, and it grows usually along streams and rivers in the eastern half of the state.
27Red Oak Tapered lobes ending in a point on the leaves Acorns about size of pennyWood is good quality and often used in woodworking furniture or finish work in homes.This is also a popular landscaping tree and is found in many suburban yards.
28HackberryLeaf—notice the base of the leaf is uneven. This makes ID easy.
33Maple sp.Acer is the genus, and there are several Maple species found in Kansas such as silver maple and sugar maple (eastern border).All species have a simple leaf with deep lobes, usually with five points.Popular landscaping tree genus because the leaves turn such beautiful colors in the fall, ranging from bright reds to oranges and yellows.Economically important because maple is a wood used for furniture and cabinetry. Sugar maples are the trees that provide the sap for maple syrup.
36Eastern Red Cedar The only native evergreen in Kansas Planted as a wind barrier and is very effectiveSpreads rapidly on prairie and is difficult to control.Highly flammable. NOT for use as a Christmas tree—has volatile oils that ignite and burn hot and fast.Wood used for fence posts, chests, closet linings, and pencils. The oil from the tree is distilled for use in soaps, perfumes and cleaners.
39RedbudUnmistakable in spring, with bright purple flowers like a pea flower, heart-shaped leaves.Common in eastern KansasOrnamental tree for landscaping because if its smaller size and very pretty pink flowers that cover the branches in spring.Beautiful, but somewhat delicate. Breaks easily if people climb or swing on it.
42Black Walnut Long, pinnately-compound leaves Fruit is about the size of a golf ball, green then turns black, with a thick husk. The nuts inside are edible. Drop from trees in October.Common in eastern Kansas. Most large trees have been harvested for lumber.Wood is dark brown, used for furniture and musical instruments, and is very beautiful.
45Smooth SumacSmall tree, generally found about 6 feet tall, in large clumps of sumac trees.The large clumps of sumac trees are actually all the same individual that has put up many little trees.Leaves have a local anesthetic in them. You can chew them up and spit them out (they taste terrible—don’t eat!) and your mouth will be numb for awhile.Berries in the fall, when red, are very tasty to suck on and then spit out (bitter if chewed up). You can also steep the berries in hot water and make a tea that tastes like the fruit. Can add sugar.
46Honey LocustNotice the extremely long thorns that cover the branches and trunk. Most of these in the picture are about 4” long.
48Honey Locust Large pinnately compound leaves Long twisted brown bean pods, flat, about 1 inch wide and 10 inches long. Can vary in lengths.VERY thorny bark—cannot miss the thorns that can exceed 6 inches in length! Thorns are found in clumps all over the tree.First tree to grow on prairie near forest—initiates the invasion of prairie by forest.Some birds, like the Loggerhead Shrike, will use the thorns to “save” prey items. Once in a while you can find small lizards, mice, birds or frogs impaled on thorns.
51Yucca (a.k.a. Soapweed) Liliaceae, the Lily family. 2-10’ tall. Stout stem rises from rigid, sword-like leaves.Flowers are 1.5” across, white.Typical of southwestern deserts, but they are also found across Kansas.Large petals are edible and are sometimes added to salads.
54Buckbrush (Coralberry) Also called CoralberryGrows in low (3 feet high) patches in open pastures or open woods.Has clusters of purple-red fruits that remain on plant all winter (too waxy for most birds, except Yellow-rumped warbler)Very common and spreads quickly
59Poison Ivy Can grow as a shrub (with compound leaves) or as a vine!!! Three, mitten-shaped leaves sometimes with a red center where leaves all meet.Vines are “hairy” and can contain the oils even when dead. Don’t ever burn firewood that has the hairy vines—oils can get in smoke, and then your eyes and lungs.Most people will react to the oils on leaves.Leaves have different amounts of oils at different times, so it is possible not to get poison ivy sometimes, and get it others.Peppermint soap and oatmeal soap both help dry and soothe the itch from poison ivy.If you know you touch it, you have about 20 minutes to wash the affected area of your skin to wash off oils.
64BittersweetClimbing vine, often along roadsides and near woodland edgesSimple, alternate, deciduous leavesFruits covered by an orange coat which splits into three sectionsFruits open in late September, exposing brilliant red seed coverOften taken by humans for decoration- but only take short side branches instead of main stem, which will kill the plant
65Bristly GreenbriarStem is covered with very sharp thorns.
66Bristly GreenbriarStem is covered with very sharp thorns.
67Bristly GreenbriarSimple, broadly egg-shaped leaves with 5 main veins that are obvious to the observer.Vine that grows in the woods and along fence rows in the eastern part of state—very common.Note the extremely thorny, black prickles that cover the main stem.Doesn’t form dense masses, but grows long.
72Virginia Creeper High climbing vine 5 palmately compound leaflets Bright red fall foliage—can’t miss it in the fall. Often seen growing on tree trunks or utility poles, and keeps its red leaves longer than the trees around it, so you can see it very easily in fall when other trees are bare.Many people think this is poison oak—we don’t have poison oak in Kansas.Not poisonous at all.
75Trumpet Creeper High climbing vine. Can grow to the top of a 20 meter tree, or sprawl over rocks and dirt banks.Excellent for erosion control.Provides great cover for animals and hummingbirds visit it.Spreads aggressively and will dominate an area.
