Livistona humilis

Livistona humilis, the sand palm, is an Australian plant species of the family Arecaceae. It is a small, slender palm, growing to about 7 m tall and 5–8 cm dbh. It has 8 to 15 fan-shaped leaves, 30–50 cm long with petioles 40–70 cm long. It is endemic to the Top End of the Northern Territory in Australia. Genetic investigation suggests that its closest relation is Livistona inermis.[2] This palm is fire tolerant and usually grows in environments where it is exposed to frequent fires.[3]

Livistona humilis is dioecious[4] and sexually dimorphic. The flower stalks on the female plant are erect and up to 230 cm long, while the male plant's flower stalks are up to 180 cm long and curved. The flowers are small and yellow, 2 mm to 4 mm across. Fruit is shiny purple black, ellipsoid, pyriform, or obovoid, 11–19 mm long and 8–10 mm in diameter.[2]

Taxonomy

The first description of the species was by Robert Brown in his Prodromus Florae Novae Hollandiae (1810). A partial taxonomic revision in 1963 resolved the typification of the genus, established by Brown to accommodate this species and Livistona inermis; Livistona humilis is recognised as the type for the genus Livistona. His collaborator Ferdinand Bauer, the botanist and master illustrator, produced artworks to accompany Brown's descriptions, but these were not published until 1838.[5] The holotype of this species was collected in January 1803 by Robert Brown from Morgans Island in the Gulf of Carpentaria.[2]

The name comes from the Latin humilis, meaning "low" – referring to its small stature.[6]

Distribution and habitat

The sand palm is endemic to the north of the Northern Territory of Australia, from the Fitzmaurice River to Cape Arnhem and inland as far as Katherine. It occurs in open forest and woodland up to about 240 m above sea level, most commonly on deep sandy soils and sandy lateritic soils, but it is found in various soils and rocky areas. It frequently grows beneath a eucalypt understorey.[2][3]

Phenology

Flowering: September to May. Fruiting: January to June.[3]

In Aboriginal culture

Aboriginal people use this palm in a number of ways. The fruits are edible. The heart (central growing tip) can be eaten, either raw or roasted. The core of the stem is pounded and made into a drink which is used to treat coughs, colds, chest infections, diarrhea, and tuberculosis. Backache is treated with the crushed stem core. The fruit and growing shoot can be used as a black or purple dye.[3] In the Yolŋu language of East Arnhem Land the palm is called dhalpi',[7] while in the Kunwinjku language of West Arnhem Land it is known as mankurlurrudj, or alternatively marrabbi in the eastern Kuninjku dialect.[8]

Conservation status

Not currently included in the Northern Territory threatened species list.[9]
