The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, subfamily Lobelioideae, all of which are endemic to the Hawaiian Islands. This is the largest plant radiation in the Hawaiian Islands, and indeed the largest on any island archipelago, with over 125 species. The six genera involved can be broadly separated based on growth habit: Clermontia are typically branched shrubs or small trees, up to 7 metres (23 ft) tall, with fleshy fruits; Cyanea and Delissea are typically unbranched or branching only at the base, with a cluster of relatively broad leaves at the apex and fleshy fruits; Lobelia and Trematolobelia have long thin leaves down a single, non-woody stem and capsular fruits with wind-dispersed seeds; and the peculiar Brighamia have a short, thick stem with a dense cluster of broad leaves, elongate white flowers, and capsular fruits. The relationships among the genera and sections remains unsettled as of April 2022.

Horace Mann Jr. was an American botanist, son of Horace Mann. His mother was one of the famous Peabody Sisters Mary Tyler Peabody Mann. Mentored in botany by Henry David Thoreau, whom he accompanied on an expedition to Minnesota, Mann took classes in zoology with Louis Agassiz and assisted William Tufts Brigham botanize the Hawaiian Islands. Mann was to have headed the botanical garden at Harvard, but died of tuberculosis at age twenty-four. His own herbarium was purchased by Cornell University and became the basis of that university's collection. He is credited with the discovery of more than 100 species.

Phyllostegia hispida, the hispid phyllostegia, is an endangered species of flowering plant in the mint family, Lamiaceae. It is found only in wet forests at elevations of 2,300–4,200 feet (700–1,280 m) on the island of Molokaʻi in Hawaiʻi. This green vine's loosely spreading branches often form a large mass.
Diospyros hillebrandii, is a species of flowering tree in the ebony family, Ebenaceae, that is endemic to the islands of Oʻahu and Kauaʻi in Hawaii.

It can be found in coastal mesic and mixed mesic forests at elevations of 150–760 m (490–2,490 ft).

Haplostachys (honohono) is a genus of flowering plants in the mint family, Lamiaceae, first described as a genus in 1888. The entire genus is endemic to the Hawaiian Islands, although 4 of the 5 known species that have been placed in the genus are now believed to be extinct, the fifth listed as "Critically Imperiled."

Phyllostegia tahitensis, commonly known as the Tahitian phyllostegia, is an extinct species of flowering plant in the mint family, Lamiaceae. It was described by Jean Nadeaud in 1873. The species was endemic to the Society Islands, primarily Mount Marau, Tahiti, where the species was thought to have perished, but botanists do not exactly know when.
Phyllostegia haliakalae, commonly known as the Haliakala phyllostegia, is a species of flowering plant in the mint family, Lamiaceae. It was described by Heinrich Wawra von Fernsee in 1872. The species Latin name derives from the Hawaiian word, "haliakala", which means "happy".
Phyllostegia variabilis is an extinct species of flowering plant in the family Lamiaceae. It was described by Friedrich August Georg Bitter in 1900. The species was endemic to the Kure Atoll, Midway Islands, and the island of Laysan, all being a part of the Northwestern Hawaiian Islands. It was under the threat of military installations on the Kure Atoll, and the Midway Islands, but on the island of Laysan was threatened by invasive alien plants and animals. The species may or may not be still alive in its natural range, but no clear evidence of its survival is evident.
