So WHY do you have to do this




Familiarize yourself with the variety of trees that
are classified as gymnosperms
Learn how to use a taxonomic key
Identify local gymnosperms
Incorporate some random trivia into your
knowledge base
This is MN and sometimes the weather is just to
yucky to actually go out to the trees, so we bring
the trees to you.
Keys to keying gymnosperms
Note key traits of leaves (shape, size, etc.)
 Note key traits of cones (size, location,
etc.)
 Note key traits of bark (color, texture)

Raised leaf stem
Bases of leaves running down the stem
Bases of leaves not running down the stem
Bases of leaves raised on stem
This is typical of a
spruce where the leaf
grows off of a small stem
