@MikesRarePlants @DrDavidLRoberts The only one you are likely to find in cultivation is Brighamia insignis (lower right). It's believed to be extinct in the wild but has been successfully grown in nurseries for years and is sometimes marketed as 'vulcan palm' (though it's completely unrelated to palms).

...and here are a few shots of mature Brighamia rockii growing in our nursery. Notice how the flowers are white compared to the more well-known yellow flowered Brighamia insignis. Both are #EndangeredSpecies endemic to #Hawaii. #EndangeredSpeciesDay https://t.co/gborcPQ7TO
