The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, 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 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.
Charpentiera is a flowering plant genus in the family Amaranthaceae. It consists of five species endemic to Hawaiʻi, where they are known as pāpala, and one species found only on the island of Tubuai in the Austral Islands. All species are trees, some reaching more than 10 metres (33 ft) in height. The genus is named for Arsène Charpentier (1781-1818), professor of pharmacy at Antwerp from 1810 to 1814 and at Cherbourg from 1814 to 1816.
Wikstroemia is a genus of 55-70 species of flowering shrubs and small trees in the mezereon family, Thymelaeaceae. Hawaiian species are known by the common name ‘ākia.
Cenchrus agrimonioides is a rare species of grass in the family Poaceae that is endemic to the Hawaiian Islands. Its common names include Kāmanomano and agrimony sandbur. It was formerly distributed throughout the major islands but today it is nearly limited to Oʻahu. Kāmanomano inhabits dry to moist forests and lava plains. It is threatened by competition with non-native plants, predation by ungulates, and wildfire. When this plant became a federally listed endangered species of the United States in 1996 there were fewer than 100 individuals remaining. More recent counts revealed 181 wild individuals on Oʻahu and over 300 more which have been planted to augment the populations. This plant is nearly restricted to the island of Oʻahu, but there are a few individuals known on Maui. A few patches of the grass have been planted on Kahoʻolawe, as well.
Phyllostegia kaalaensis, the Kaala phyllostegia, is a species of flowering plant in the mint family, Lamiaceae, that is endemic to the island of Oʻahu in Hawaiʻi. It can be found in mesic forests on the slopes of the Waiʻanae Range at elevations of 374–796 metres (1,227–2,612 ft).
Phyllostegia is a genus of flowering plant in the mint family, Lamiaceae, first described in 1840. It is native to certain islands in the Pacific.

Phyllostegia mollis, the Waianae Range phyllostegia, is a species of flowering plant in the mint family, Lamiaceae, that is endemic to Hawaiʻi. It can be found in mesic and wet forests at elevations of 450–1,830 metres (1,480–6,000 ft) on the islands of Maui and Oʻahu. Some authors consider it to be an Oahu endemic, with the Maui populations belonging to a separate species, Phyllostegia pilosa. By 2003 there were fewer than 40 individuals remaining. It is threatened by habitat loss.
