Resedaceae
Resedaceae is a family of mostly herbaceous dicotyledonous plants comprising 107 known species in 8 to 12 genera:
- Borthwickia - 1 species, sometimes placed in its own family Borthwickiaceae
- Caylusea - 3 species
- Forchhammeria - 10 species
- Homalodiscus - 2 species
- Neothorelia - 1 species
- Ochradenus - 4 species
- Oligomeris - 3 species
- Randonia - 1 species
- Reseda - ca 55 species
- Sesamoides - 1 species
- Stixis - 7 species
- Tirania 1 species
Recent molecular studies suggest that Oligomeris, Randonia and Ochradenus all arose from within the ranks of Reseda. This would imply that only three genera should be recognized, although as yet no nomenclatural changes have been made.
The family includes annuals, biennials and perennials and is distributed in temperate to sub-tropical regions of Europe, western Asia, the Middle East, East Asia, North America, Mesoamerica, the Caribbean and South Africa.
Resedaceae were placed under the Cronquist system in the order Capparales. The APG II system places it in the order Brassicales. In APG IV it was expanded to include the genera Borthwickia, Neothorelia, Stixis, and Tirania and Forchhammeria
