The plant family of xanthorrhoeaceae (Xanthorrhoeaceae s. L.) Belongs to the order of the asparagus-like (Asparagales) within the monocotyledonous ( monocot ). The botanical genus name Xanthorrhoea is derived from the Greek xanthos for yellow and rhoe for flow and refers to the resin. Some species are used as solitary, decorative ornamental plants in frost-free areas in parks and gardens.
Systematics and distribution
The species of the family Xanthorrhoeaceae s. l. thrive from temperate to tropical climates.
The molecular genetic investigations in the last ten years have led to the fact that the family boundaries within the order of the Asparagales have shifted significantly. The systematics of this genus, subfamily, family, has been discussed for a long time, so one will often encounter seeming inconsistencies in the literature. The systematics according to Mark W. Chase et al. 2009. The Xanthorrhoeaceae Dum family. was extended to include the taxa of the former families of the Affodilla family (Asphodelaceae) and the daylily family (Hemerocallidaceae). The family name Xanthorrhoeaceae was first published in 1829 by Barthélemy Charles Joseph Dumortier in Analyze des Familles de Plantes , 60, 62, 103. The type genus is Xanthorrhoea Sm.
There are three subfamilies in the grass tree family Xanthorrhoeaceae today:
- Affodilla family (Asphodeloideae Burnett ): The approximately 15 genera with approximately 785 species come from Africa , especially in the Capensis, across the Mediterranean to Central Asia , Australia and New Zealand .
- Daylily family (Hemerocallidoideae Lindl. ): The approximately 19 genera with approximately 85 species in a disjoint area from Papua Asia to New Zealand and the Pacific, especially in Australia, but also from Europe to Asia, Malesia , India , Madagascar , Africa and two genera in South America .
- Xanthorrhoeoideae MWChase, Reveal & MFFay : It contains only one genus:
- Xanthorrhoea Sm .: The approximately 28 species are only native to all states of Australia and Tasmania .
The genus Kingia was often assumed to also belong to this family group; however, it belongs to the Dasypogonaceae family .
Affodill ( Asphodelus albus )
Yellow affodilla ( Asphodeline lutea )
Yellow-red daylily ( Hemerocallis fulva )
