Xanthorrhoeaceae

Xanthorrhoea malacophylla

The plant family of grass tree plants ( Xanthorrhoeaceae sl) belongs to the order of the asparagus -like ( Asparagales ) within the monocots ( monocotyledons ). The botanical genus name is derived from the Greek xanthorrhoea xanthos for yellow and Rhoe for flow and refers to the resin. Some species are used as stand alone, decorative ornamental plants in frost- free areas in parks and gardens used.

Systematics and distribution

S. L. The types of Xanthorrhoeaceae family thrive from the temperate to the tropical climate.

The molecular genetic studies in the last ten years have meant that the family boundaries within the order of asparagus -like ( Asparagales ) have dramatically shifted. The systematics of this genus, subfamily, family, was discussed at length, so it is in the literature often encounter apparent inconsistencies. Shown here is the classification by Mark W. Chase et al. 2009th The Xanthorrhoeaceae Dum family. has been extended to the taxa of the former families Asphodelus ( Asphodelaceae ) and Tagliliengewächse ( Hemerocallidaceae ). The family name was first published in 1829 by Xanthorrhoeaceae Barthélemy Charles Joseph Dumortier in analysis of Familles de Plantes, 60, 62, 103. Type genus is Xanthorrhoea ( Sm ). The botanical genus name Xanthorrhoea and hence the name Xanthorrhoeaceae derives from the Greek words for xanthos yellow and Rhoe for flow and refers to the resin.

In the family of grass tree plants Xanthorrhoeaceae today there are three subfamilies:

  • Asphodeloideae Burnett: The approximately 15 genera with about 785 species come from Africa, especially in the capensis, on the Mediterranean to Central Asia, Australia and New Zealand before.
  • Hemerocallidoideae Lindl. , The approximately 19 genera with about 85 species in an area of ​​Papua disjunktem Sien to New Zealand and the Pacific, particularly in Australia, but also from Europe to Asia, Malaysia's, India, Madagascar, Africa and two species in South America.
  • Xanthorrhoeoideae MWChase, Reveal & MFFay: it contains only one genus: Xanthorrhoea Sm: The approximately 28 species are native only in all states of Australia and in Tasmania.

From the genus Kingia was often assumed that it belongs in this family circle; However, it belongs to the family of Dasypogonaceae.
