Molecular data confirm the phylogenetic placement of the enigmatic Hesperocallis (Hesperocallidaceae) with Agave

Hesperocallis is a monotypic genus endemic to western North America, currently classified in Hesperocallidaceae (sensu Angiosperm Phylogeny Group 1998, 2003) but typically placed in Liliaceae (sensu Cronquist 1988) in floristic treatments. On the basis of DNA sequence data, the phylogenetic placemen...

Description
Summary:Hesperocallis is a monotypic genus endemic to western North America, currently classified in Hesperocallidaceae (sensu Angiosperm Phylogeny Group 1998, 2003) but typically placed in Liliaceae (sensu Cronquist 1988) in floristic treatments. On the basis of DNA sequence data, the phylogenetic placement of Hesperocallis is demonstrated to be with Agavaceae, rather than with Alliaceae, Hemerocallidaceae, or Liliaceae as thought by earlier authors based on morphology. Based on these results, we recommend sinking Hesperocallidaceae in Agavaceae within Asparagales. Hesperocallis es un género monotípico endémico del oeste de América del Norte. Actualmente, Hesperocallis está clasificado dentro de Hesperocallidaceae (Angiosperm Phylogeny Group 1998, 2003); sin embargo, previas clasificaciones basadas en morfología lo han situado al interior de Liliaceae (sensu Cronquist 1988). Con base en secuencias de ADN, Hesperocallis esta filogenéticamente emparentado con la familia Agavaceae y no con Alliaceae, Hemerocallidaceae o Liliaceae como fue sugerido por previos autores. Como resultado, recomendamos considerar a Hesperocallidaceae como parte de Agavaceae dentro de las Asparagales.
