Campynemataceae (Campynemaceae) is a family of flowering plants. The family consists of two genera and four species[5] 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.[6] Together the two genera make up the family Campynemataceae sensu Angiosperm Phylogeny Group (APG), within the Liliales order.[7]
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.[4]
Phylogeny
The synthesis of molecular data with cladistic analysis suggests that the Liliales form one of eleven orders of monocotyledons.[8] Sequencing of the rbcL and trnL-F plastid genes revealed four main Liliales lineages:[9]
- Liliaceae group: Liliaceae (including some former Uvulariaceae and Calochortaceae), Philesiaceae and Smilacaceae;
- Campynemataceae;
- Colchicaceae group (Colchicoid lilies): Colchicaceae (including Petermannia and Uvularia), Alstroemeriaceae and Luzuriaga;
- Melanthiaceae (including Trilliaceae).
This suggested that the Campynemataceae form one of seven families within the Liliales order.
