The plant family Nyctaginaceae was named and described by Antoine Laurent de Jussieu in Genera Plantarum in 1789.

The only species I am familiar with in this family so far is the wildflower Mirabilis nyctaginea (Wild Four O-Clock). You can click on the name to go to its own page.
I have included a few links for further reading…
