1. Classification of trees

2. Classification of trees


Conifers
Broadleaved trees

Needle-like leaves
Scale-like leaves
Compound leaves
Simple leaves

3. Classification of trees

Coniferous trees generally have narrow, hard
leaves that are known as scales or needles,
depending on their shape. Nearly all of them are
evergreen.
Conifers do not have true flowers; instead, they
produce cones.
