Plumeria, commonly known as frangipani, is a genus of flowering plants in the family Apocynaceae (order Gentianales), comprising approximately 18 accepted species of deciduous shrubs and small trees. The genus is native to the Neotropical realm — ranging from Mexico, Central America, and the Caribbean southward to Brazil and as far north as Florida — but has been widely cultivated as an ornamental across tropical regions worldwide, particularly in Hawaii and in irrigated desert gardens of the Arabian Peninsula.
Plants in this genus are distinguished by their succulent branches and by the milky latex sap that exudes from cut surfaces. This latex, like that of many Apocynaceae relatives, contains poisonous compounds that can irritate the eyes and skin on contact. The flowers, borne at branch tips, are intensely fragrant and are among the most recognisable tropical blooms; cultivated varieties span a wide palette from white and yellow through deep pink and red.
Within Apocynaceae, Plumeria is placed in the subfamily Rauvolfioideae, tribe Plumerieae, and subtribe Plumeriinae — a group that also includes the closely related genera Himatanthus and Mortoniella. The type species is Plumeria rubra, designated in 1925 by Nathaniel Lord Britton and Percy Wilson. The genus carries more than 100 names now regarded as synonyms, many formerly assigned species having been transferred to Himatanthus as taxonomic understanding improved. The genus was named by Joseph Pitton de Tournefort in 1700 in honour of Charles Plumier, a fellow French botanist who explored the tropical Americas as Louis XIV's royal botanist and described a large number of New World species.
Etymology
The genus name Plumeria was coined by Joseph Pitton de Tournefort in 1700 to honour Charles Plumier, a French botanist who served as Louis XIV's royal botanist and extensively documented plant species across the tropical Americas. The name was formally published by Carl Linnaeus in 1753 in his Species Plantarum, where he described the three species then known: P. rubra, P. alba, and P. obtusa.
Distribution
Plumeria is native to the Neotropical realm, with its natural range spanning Mexico, Central America, the Caribbean, and south to Brazil; the northernmost natural occurrences reach Florida in the United States. The genus has been extensively cultivated well beyond this native range and is a characteristic ornamental plant of Hawaii and other Pacific island groups, as well as of irrigated gardens in the hot desert climates of the Arabian Peninsula.
Taxonomy Notes
Plumeria belongs to subfamily Rauvolfioideae within Apocynaceae, placed in tribe Plumerieae and subtribe Plumeriinae alongside Himatanthus and Mortoniella. The genus currently comprises about 18 accepted species, with over 100 names treated as synonyms — many formerly assigned to Plumeria have been transferred to Himatanthus. The type species, Plumeria rubra, was designated in 1925 by Britton and Wilson. The name was first applied by Tournefort in 1700 but Linnaeus provided the formal publication in 1753.
Cultural Uses
Plumeria flowers hold deep cultural significance across many tropical societies. In Hawaii, the blooms are among the most commonly used flowers in lei-making and are strongly associated with the islands' identity. Across South and Southeast Asia, frangipani flowers are used in religious offerings and ceremonies; in Bali and much of Hindu and Buddhist practice, the flowers are placed on temple altars and as personal offerings. The flowers are also used in perfumery, and the characteristic frangipani scent is widely reproduced in cosmetics and personal care products globally.
