  1. Tree Pictures for Taxonomy Honors Biology Mr. Hirn

  2. D*H*A*M Trees • Dogwood • Simple • Entire Margin

  3. D*H*A*M Trees • Horse Chestnut • Palmate Compound • AKA “Buckeye”

  4. D*H*A*M Trees • Ash • Pinnate Compound • Have been decimated in Michigan by an infestation of the Emerald Ash Borer.

  5. D*H*A*M Trees • Maple • Simple Leaf • Palmate Lobes • Several species found in Michigan

  6. Sugar Maple • Five Lobes • Seeds point down • Canada’s Symbol

  7. Norway Maple • Similar to Sugar Maple • Seeds point out • White “ooze” from the base of the petiole

  8. Silver Maple • Very deep sinuses • Underside of leaf is light silvery color • Very soft wood • Invasive roots

  9. Red Maple • Only three lobes • 90o angle on sinuses • Very hard wood • Bright red leaves in fall

  10. Elm • Alternate on branch • Simple leaf • Serated margin • Rough texture to leaf surface • Pinnate veins • Assymetrical (uneven) base • VERY short petiole

  11. Paper Birch • Simple Leaf • Serrated Margin • “Catkins” for seeds • White, papery bark • Has “lenticels” to allow gas exchange

  12. Black Walnut • Pinnately compound • Long leaf with many leaflets • Dark wood • Has a chemical (tannic acid) That is used to preserve leather • Heavy seeds (walnuts)

  13. Sassafrass • AKA “Michigan Tree” or “Mitten Tree” (also “Ghost Tree”) • Smooth margin • 3 different shapes • Roots used to make root beer • Leaves make Sassafrass Tea • Crushed leaves have a sweet smell

  14. Mulberry • Serrated Margin • 3 different shapes • Dark berries • AKA Huckleberries or June berries • Very invasive plant

  15. Black Locust • Pinnately compound • Round, oval leaflets • Dark green • Young trees have sharp thorns • Mature trees have thick bark

  16. White Oak • Simple leaf • Rounded, pinnate lobes • Seeds are acorns

  17. Red or Black Oak Black Oak • Different species • Simple leaf, pinnate & pointed lobes • Leaves are so similar that we will ID them as the same • Acorns are different Red Oak

  18. Pin Oak • Simple leaf • VERY deep sinuses • Branches extend out from trunk at 90o

  19. Black Cherry • Simple leaf • VERY small serrations • Separate male & female trees • Known as Dioecious • Has orange “fuzz” on the underside of the midrib

  20. Conifers • Pines • Spruce • Firs • Cedars • Plus the “Exceptions” • Tamaracks • Yews

  21. White Pine • Five needles per fascicle • Long, soft needles

  22. Jack Pine • Two needles per fascicle • 1” – 2” needles • Cones need fire to open and release their seeds • Only tree in the world in which the Kirkland’s Warbler will nest

  23. Red or Black Pine • Two needles per fascicle • 4” – 6” needles

  24. Scotch (Scot’s) Pine • Two needles per fascicle • 3” – 4” needles • “Butterscotch” color to bark

  25. Blue Spruce • Single needle • Diamond shape X-Section • Bluish tint to new growth

  26. Norway Spruce • Single needle • Diamond shape X-Section • Pointed tip • Dark green color • “Droopy” branches

  27. Hemlock Fir • Single needle • Flat X-Section • Blunt (rounded) tip • Very small needles • Very small cones • Green stripes on underside of needle

  28. Douglas Fir • Single needle • Flat X-Section • Blunt (rounded) tip • “Whiskers” on cones (bracts)

  29. Red Cedar • Scale-like needles (overlapping) • Very small • Have sharp points

  30. White Cedar • Scale-like needles (overlapping) • Larger than red cedar • and also flatter • Has a “softer” feel and appearance

  31. Exceptions* • Tamarack • Circular clusters of needles • Very soft needles • New growth has single needles • Old growth has clustersDeciduous conifer

  32. Exceptions* • Yew • Single needle -Resembles a fir • Flat cross-section • Has pointed needles -Not blunt like a fir

  33. Various Odd and Interesting Trees • Not necessarily trees we have on campus, or that we have seen on our tours.

  34. Basswood • Simple leaf • Serrated margin, long petiole • Uneven base • Unique (fishing lure) seed

  35. Sycamore • Looks like a maple • Pointed, palmate lobes • ALTERNATE on branch • Not a D*H*A*M tree • Unique bark pattern • Looks “sick”, peeling off • Camoflage pattern

  36. Honey Locust • Compound leaf • Some are DOUBLE compound • Common landscape tree

  37. Weeping Willow • Simple leat • Resembles a compound leaf • Branch is so flexible • Fast growing • Typical in wet areas

  38. Catalpa • Simple leaf • Smooth margin, long petiole • Has whorled leaf arrangement • VERY large leaf • Long, bean-like seeds

  39. Japanese Maple • Simple leaf • Deep sinuses • Palmate lobes • Multiple lobes • Not a native Michigan tree • Used in landscaping • Needs protection from harsh winter winds • Some will grow wild

  40. Box Elder • Actually a Maple • D*H*A*M Tree • Has a compound leaf with three leaflets Does have “helicopter” seeds

  41. Virginia Creeper • Actually a vine • Resembles Horse Chestnut • Middle of leaflet is wider than the base • Grows in heavy shaded areas
