Monocotyledon

The name for one of the two former groups (the other being Dicotyledon) into which Angiosperms were categorized. Monocotyledons are now one of several groups within the Angiosperm Clade (group).

These are plants with embryos that have one cotyledon (hence 'mono') and typically have the following characteristics:
• They are mostly herbaceous plants (they lack secondary thickening).
• The floral parts are grouped in 3s.
• They have a fibrous root system, developing further from adventitious roots.
• The vascular bundles are scattered irregularly throughout the root and stem.
• The major leaf veins are parallel veined.
