Ixora is a genus of flowering plants in the family Rubiaceae. It is the only genus in the tribe Ixoreae. It consists of tropical evergreen trees and shrubs and holds around 544 species. Though native to the tropical and subtropical areas throughout the world, its centre of diversity is in Tropical Asia. Ixora also grows commonly in subtropical climates in the United States, such as Florida where it is commonly known as West Indian jasmine. Other common names include viruchi, kiskaara, kepale, rangan, kheme, ponna, chann tanea, techi, pan, siantan, jarum-jarum/jejarum, jungle flame, jungle geranium, and cruz de Malta, among others. The plants possess leathery leaves, ranging from 3 to 6 inches in length, and produce large clusters of tiny flowers in the summer. Members of Ixora prefer acidic soil, and are suitable choices for bonsai. It is also a popular choice for hedges in parts of South East Asia. In tropical climates, they flower year round and are commonly used in Hindu worship, as well as in ayurveda and Indian folk medicine.
Reynoldsia is a formerly recognised genus of plants in the ivy family, Araliaceae. In 2003, Kew Gardens published a checklist for Araliaceae, in which eight species were recognized for Reynoldsia: four from Samoa, two from Tahiti, one from the Marquesas, and one from Hawaii. In 2010, a phylogenetic comparison of DNA data showed that Reynoldsia was polyphyletic, consisting of two groups that are not each other's closest relatives. In a companion paper, three of the species were "sunk" into synonymy with others, reducing the number of species to five. All species that were formerly in Reynoldsia are now in Polyscias subgenus Tetraplasandra, a subgenus of 21 species indigenous to Malesia and the Pacific islands.
Fitchia is a genus of flowering plants in the sunflower family, 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.
