I want to identify a tree from one of the 12 species listed based on observing their branch and leaves. Is there quick and neat way to do it?

Red Oak, White Oak, Red Maple, Striped Maple, Tulip Poplar, Black Cherry, White Pine, Virginia Pine, Dogwood, Hickory Species, Sourwood and Cucumber Magnolia.

Thank you!

    $\begingroup$ Yes. Get examples of each tree (or Google), then memorize their structure and features. It's quite easy... $\endgroup$

    $\begingroup$ Becoming familiar with the leaves and bark of various trees really is the best way of identifying them, even if you just know it's an oak tree, for example, but not what kind, as all oaks have the same basic leaf structure. Learning to identify the subtypes just takes a little more work. $\endgroup$

    $\begingroup$ @MattDMo I understand, but that should be so obvious of a method as to not warrant a question, at least not in a day and age of Google. Say I was going on a trip to the American Southwest and I wanted to be able to identify the different types of Cacti, I'd do a few Google searches. I think we need to start a stack for questions on how to do basic queries. There is only one thing that I can think of that would warrant that, and it is if the OP is in a country that censors sites such as Google, etc. What we take for granted in Western countries cannot be taken for granted elsewhere. $\endgroup$

  • $\begingroup$ @AMR let's discuss this more in chat - it's not really pertinent to this question. $\endgroup$

A good first step is to pay attention to common differences between tree structure:

1. Alternate vs. Opposite structure

  • MADHORSE = your common eastern US opposite-leaved trees are Maple, Ash, Dogwood, and Horsechestnut (AKA buckeye).

2. Simple vs. compound leaves

enter image description here

3. Toothed ("entire") vs. untoothed leaves

enter image description here

4. Lobed vs. unlobed leaves

enter image description here

5. Differences in texture, hairiness, & color of leaves

  • both b/w species and b/w top/bottom of leaves of the same species

Generally when you come across a new tree in Eastern N. America I'd recommend going through these steps:

  1. Is it alternate or opposite?
  2. Is it simple or compound?
  3. Is it toothed, doubly-toothed, or smooth along the edge?

If you can answer yes to (any or all of) those questions you typically SIGNIFICANTLY reduce your options.

You also want to make sure you're aware of large variations in some species (especially oaks and hickories). One good example is the difference in shape, texture, and color of sun leaves vs. shade leaves of many species.

Importantly, paying attention to WHERE the tree is located (and what else is growing around it) as this can really help narrow your choices. You'll also start recognizing common cohabitants of certain regions.

Finally, don't be afraid to use your many senses (smelling, feeling and even tasting) -- though get to know poison ivy well before you start licking plants!!

Ok, now for some useful hints:

  • Red Oak = stereotypical oak shape, smooth on both side of leaf, lobes are not deep. You'll find 'spikes' at the end of each lobe. Bark looks like it has vertical shiny stripes.

  • White Oak = rounded SMOOTH lobes. Bark light grey/white with flaking appearance when mature

  • Red Maple = OPPOSITE. Leaves serrated (toothed). Smooth grey bark (with few low-hanging branches)
  • Sugar Maple = OPPOSITE. Leaves NOT serrated. Smooth whiter grey bark.
  • Striped Maple = OPPOSITE. Maple-like shape, but with rounded/butt-shaped (cordate) base. Bark = very striped in appearance.
  • Tulip Poplar = Leaf-shape looks like a tulip flower. Tree tall and straight.
  • Black Cherry = Oval/round leaves with fine single-toothing along edge. Tuft of brown/white fur along mid-rib on underside of leaf. Bark = horizontal striping due to lenticels; gets flaky when mature. Bark/twigs have strong bad smell when scratched (cyanide).
  • White Pine = 5 relatively long wispy needles per cluster.
  • Virginia Pine = 3 Short, dense needles per cluster. Bark has cornflake appearance.
  • Dogwood = OPPOSITE. round leaf with deep ribbing veins and drip tip. Leaves often look to be growing in pairs. If you pull a leaf apart carefully, you'll find some thin tissues dangling between the halves. The bark is cobblestone (mosaic bumpy) and the shape of the tree is typically flat-umbrella-esque.
  • Hickory Species = VERY DIFFICULT TO TELL SPECIES APART (though I can give you a bunch of hints to help). Fairly easy to tell apart from other species, though. Is ALTERNATE + COMPOUND with generally 5-9 leaflets per leaf. (unlike ash = opposite/compound or walnut = compound with MANY leaflets). Leaves often carry some odor and large seeds can be found nearby
  • Sourwood = Long, oval, tiny-toothed leaves that have strong sunken midrib and thin leaf texture. Tastes very sour. Bark is dark and ridged, and trunks very rarely grow straight (so look for crooked or leaning trees!).
  • Cucumber Magnolia = Look for LARGE, strongly veined leaves that are often drooping. Look for circular ring (stipule scar) beneath leaf petiole base.
