[edit]
Brighamia are 1–2.5(–5) m tall, cremnophytic, halophytic, perennial, succulent, caudiciform plants with thick, mostly unbranched stems[3] bearing numerous obovate, sessile or petiolate, nearly entire, rosette-like leaves at the apex of the stem.[1] The stem and foliage produce latex.[1]

Taxonomy
[edit]It was described by Asa Gray in 1867[4] with Brighamia insignis A.Gray as the type species.[1]
Species
[edit]The genus has two species:[2]
- Brighamia insignis A.Gray
- Brighamia rockii H.St.John
Distribution and habitat
[edit]The genus is endemic to Hawaii.[2]
Conservation
[edit]Brighamia species are threatened by extinction, as Brighamia rockii is Critically Endangered (CR)[5] and Brighamia insignis is already Extinct in the Wild (EW).[6] Both Brighamia rockii[7] and Brighamia insignis are kept in ex-situ collections in botanic gardens.[8] Brighamia insignis is also cultivated as a house plant.[9] The Brighamia insignis in cultivation have only limited genetic diversity.[10]
