Glossary
Some of the characteristics used to identify
your plant specimen may be unfamiliar to
you. Please familiarize yourself with the
glossary information below to assist in your
search.
Select the color that most closely resembles
the color of your plant specimen. If
your specimen has more than one color, first
search by the predominant colors. For
these reasons, try searching by other color
possibilities if your search does not yield
any species that match your specimen.

Monocots and Dicots
Flowering plants or Angiosperms are the largest and most diverse group of plants. Angiosperms are divided into Monocots and Dicots. Monocots have one seed leaf and Dicots have 2 seed leaves.
Monocots: Can be determined by:
Flower parts (sepals, petals, stamens) usually in multiples of 3's.
Major leaf veins usually in parallel arrangement.
Dicots: Can be determined by:
Flower parts usually in multiples of 4's or 5's.
Major leaf veins usually in netted or reticulated arrangement.
