Plants are divided into two broad categories: monocots and dicots.

Dicotyledons (dicots, broadleaves)

  • Embryo has two cotyledons
  • Leaves are usually palmately or pinnately veined, and are usually broader and stalked (i.e., they have a petiole)
  • Flower parts usually occur in fours or fives

Identification of dicots is based on the variability in the morphological characteristics such as: leaf arrangement, attachment, type, venation, shape, and margin; flower arrangement and form; fruits, stems and roots.
