Atlas of Botany: Monocotyledons and Dicotyledons

Angiosperms

There are about 250,000 known species of flowering plants belonging to two taxonomically distinct groups: Monocotyledons and Dicotyledons.
Their names derive from the number of cotyledons or seminal leaves (1 for monocotyledons 2 for dicotyledons).
