• Venation is parallel.
• Stems are stout, solid with distinct nodes and internodes.
• Roots are of fibrous type.

Canna

• The leaf blades are elongated or oval in shape but come to a point at the tip.
• They are hairless, have entire margins, and narrow at the base where they join to the top of the leaf sheath.
• The petioles and leaves of Canna exhibit several hydrophytic characteristics, including very conspicuous airspaces that traverse the petiole and leaf blade structure.
