Licuala is a large genus of fan palms in the family Arecaceae (order Arecales), placed within the tribe Trachycarpeae. The genus comprises approximately 149 accepted species, distributed across tropical forests from southern China and the Himalayas through Southeast Asia to New Guinea and the islands of the western Pacific Ocean.
The palms are immediately recognisable by their striking foliage: the leaves are large and mostly circular in outline, borne on slender petioles, and range from completely undivided to deeply divided into wedge-shaped (cuneate) segments arranged like the spokes of a wheel. This fan-palm architecture makes many Licuala species distinctive in the understorey of humid tropical forests, where the genus occupies shaded, often moist habitats.
Licuala has a history of taxonomic revision. Several species formerly placed here have been transferred to the segregate genus Lanonia, reflecting ongoing phylogenetic refinement within the tribe Trachycarpeae. The genus name is attributed to Wurmb, with an earlier nominal reference by Thunberg published in 1782.
Among the more culturally noted species, Licuala acutifida supplies the cane used for the walking stick known to colonial writers as the "Penang-lawyer," a name derived from the Malay phrase pinang liyar (wild areca palm). Some Licuala species — particularly Licuala grandis from Vanuatu and Licuala ramsayi from Australia — are widely grown as ornamentals in tropical and subtropical gardens and as indoor foliage plants in cooler climates.
Etymology
The genus name Licuala is attributed to Wurmb (with a prior Thunberg reference from 1782); it derives from leko wala, the local Ternatan (North Moluccas) name for one of the species as recorded by early European naturalists in the Indonesian archipelago. The common colonial term "Penang-lawyer" for canes made from Licuala acutifida reflects the genus's long history of human use in Southeast Asia.
Distribution
Licuala species occur in tropical forests of southern China, Southeast Asia (including the Malay Peninsula, Borneo, the Philippines, and the Indonesian archipelago), the Himalayan foothills, New Guinea, and western Pacific islands including Australia's northeastern coast. The center of diversity lies in Southeast Asia and Malesia.
Cultivation
Several Licuala species are cultivated as ornamental palms in tropical and subtropical gardens, valued for their architectural circular leaves. Licuala grandis (ruffled fan palm) and Licuala ramsayi are among the most widely grown; they prefer partial shade, humid conditions, and well-drained but moisture-retentive soils, reflecting their forest-understorey origins.
Taxonomy Notes
Licuala is placed in the tribe Trachycarpeae of the family Arecaceae. The genus has undergone revision: several species have been moved to the segregate genus Lanonia. The authorship is contested between Wurmb and Thunberg (1782); the GBIF backbone treats Licuala Thunb. as DOUBTFUL while a separate accepted record exists. Plants of the World Online accepted 149 species as of March 2026.
