Campynemataceae

Campynemataceae (Campynemaceae) is a family of flowering plants. The family consists of two genera and four species of perennial herbaceous plants endemic to New Caledonia and Tasmania.
Taxonomy.
Originally described by Dumortier in 1829, Campynemaceae consisted of a single genus, "Campynema", described by Labillardière in Tasmania in 1804. In 1893 Baillon identified a closely related genus, "Campynemanthe" in New Caledonia. Together the two genera make up the family Campynemataceae sensu Angiosperm Phylogeny Group (APG), within the Liliales order.
While historically, the two genera have generally been treated together, their circumscription has varied considerably. The third edition (1903) of Engler's "Syllabus" only included Campynema, but positioned it as Campynematoideae, a subfamily of Amaryllidaceae.
Phylogeny.
The synthesis of molecular data with cladistic analysis suggests that the Liliales form one of eleven orders of monocotyledons. Sequencing of the "rbcL" and "trnL-F" plastid genes revealed four main Liliales lineages:
This suggested that the Campynemataceae form one of seven families within the Liliales order.
