Tree Quiz

This page lets you set up a quiz about trees that you can take. You can tailor it to your particular preferences, or just hit "Create a Quiz" and take a general test. There are also quiz programs for wildflowers and birds.

If you are more interested in identifying trees, see the tree identification page.

How many questions would you like to answer?

You can choose the types of questions you want to answer:
   Yes/No questions
   Which tree has this characteristic?
   Which characteristic does this tree have?
   For these two characteristics, which tree has both?
   For these two trees, which characteristic is common to both?

You can select which characteristics you wish to be quizzed on:
  Needles per Cluster
  Single Needles
  Length of Needles
  Flattened Needles
  Length of Cones
  Leaf Edges
  Leaf Arrangement on Twig
  Simple Leaves Only
  Compound Leaves Only

You can choose what types of trees you would like to be quizzed on, as a group. Checking a characteristic in a group means trees in that group will be used for making questions. If you check a number of characteristics in one group (e.g. Needles per Cluster), trees with either of those characteristics will be part of the group (not just trees with both characteristics). If you check characteristics in different groups, the set of trees for each separate group is found, then trees that are common to all sets are used. Technically, within a group it's "characteristics OR char. OR char." and overall it's "group AND group AND group".

Yes, this all sounds confusing, but the idea is that you can choose to be tested on trees that have in common two or more specific sets of characteristics from different groups. For example, if this program were for house types, there might be two groups, Number of Stories and Exterior Wall Material. You could pick the characteristic "one-story" from the first group, and "stucco" and "brick" from the second, and the group of all houses used would then be "one-story AND (either stucco OR brick)". Try it out and see.

Check the characteristics below:
Needles per Cluster
   Two needles per cluster
   Three needles per cluster
   Five needles per cluster
   Twelve or more needles per cluster
Single Needles
   Needles 4-angled in cross-section
   On peg-like bases, twigs remain rough even after needles removed
   Round needle-scars on twig, twigs rather smooth after needles removed
   Some needles scale-like
   Some needles 3-angled (V) in cross-section
Length of Needles
   Length of Needles less than 1"
   Length of Needles 1-2"
   Length of Needles 1 1/2-3"
   Length of Needles 3" or more
Flattened Needles
   Flattened needles have 2 white lines beneath
   Flattened needles have no white lines beneath
Length of Cones
   Length of cones 1" or less
   Length of cones 1-2"
   Length of cones 1 1/2-3"
   Length of cones 3" or more
   Conifer fruit is Berry-like
   Fruit is an acorn
   Fruit is a capsule
   Fruit is winged
   Fruit is a catkin
   Fruit is seed-like or a prickly ball

   Leaf Arrangement is opposite
   Leaf Arrangement is alternate
Simple Leaves Only
   Leaves have a heart-shaped base
   Leaves have a "V"-shaped base
   Leaves have a fairly equal base
   Leaves have a lopsided base
   Leaves are about as long as broad
   Leaves are about 1 1/2-3 times as long as broad
   Leaves are more than 3 times as long as broad
   Leaves are not lobed
   Leaves have palmate lobes
   Leaves have pinnate lobes with bristle tips
   Leaves have pinnate round lobes
   Leaves have a flat petiole
Compound Leaves Only
   Number of pinnate leaflets for compound leaves is mostly 3
   Number of pinnate leaflets for compound leaves is mostly 5
   Number of pinnate leaflets for compound leaves is mostly 7-9
   Number of pinnate leaflets for compound leaves is 10 or more
   Compound leaves have palmate leaflets

I started this project back in 1984, believe it or not, and am doing it purely for fun. If you like this program enough to feel like showing your appreciation, please consider becoming a member or giving a tax-deductible charitable contribution to the Cornell Plantations. I have no affiliation with this fine institution; rather, I was married many years ago in their beautiful herb garden.
