MONOCOTYLEDONEAE. 



These Plants are characterised by the embryo bearing only one 

 cotyledon. The leaves are as a rule alternate, with simple form, 

 parallel venation, and a broad sheathing base. The stem and root 

 show no secondary thickening of the type usual in Dicotyledons, 

 their vascular strands having no cambium. The flower is constructed 

 usually of five alternating whorls of parts, and each whorl is commonly

 and bulbous plants that are grown for the beauty of their flowers.
