Xanthorrhoeaceae Dumort., nom. cons.
the grass tree family
The name of Xanthorrhoea, the type genus, is derived from two Greek words, ξανθος (xanthos), yellow, and 'ρεω (rheo), to flow, referring to the yellow gum that can be extracted from the plant. Members of the family are very diverse, and are divided into 3 subfamilies:
• Xanthorrhoeaceae: containing only one genus, Xanthorrhoea, the Australian grass trees. These are incredibly slow growing, typically develop thick woody stems, with flowers arranged in a dense spike.
• Hemerocallidoideae: varied in habit, the daylilies probably being the best known members.
