hemerocallidaceae การใช้

• Johnsoniaceae and Hemerocallidaceae " sensu stricto " form a clade that has strong bootstrap support.
• In the 21st century, Hemerocallidaceae has been defined in essentially two different ways in systems based on monophyletic groups.
• The broader version of the family, Hemerocallidaceae sensu lato, includes those species that would otherwise be assigned to Johnsoniaceae.
• The broader version of Hemerocallidaceae is the one that was accepted by the Angiosperm Phylogeny Group when they published the APG II system in 2003.
• In the APG II system of APG III in 2009, Hemerocallidaceae was combined with two other families, called Asphodelaceae in the APG IV system.
• Three separate families were at one time recognized ( e . g . in the first APG system of 1998 ) : Asphodelaceae, Hemerocallidaceae and Xanthorrhoeaceae.
• When this system was superseded by APG III in 2009, Hemerocallidaceae was not recognized, instead being treated as subfamily Hemerocallidoideae of the expanded family Xanthorrhoeaceae " sensu lato ".
• The decision to group three formerly separate families, Asphodelaceae sensu stricto, Hemerocallidaceae and Xanthorrhoeaceae, into a single family first occurred as an option in the APG II system of 2003.
• The single genus in the family, " Xeronema ", with two species, has been variously placed in the family Asphodelaceae or the family Hemerocallidaceae in other taxonomic systems.
