Livistona

Livistona is a genus of palms, the botanical family Arecaceae, native to southeastern and eastern Asia, Australasia, and the Horn of Africa.[2] They are fan palms, the leaves with an armed petiole terminating in a rounded, costapalmate fan of numerous leaflets.[3][4][5]

Taxonomy

edit

The genus was established by Robert Brown in his Prodromus Florae Novae Hollandiae (1810) to accommodate his descriptions of two species collected during an expedition to Australia. The names published by Brown were Livistona humilis and L. inermis, describing material he had collected in the north of Australia, a partial taxonomic revision in 1963 nominated the first of these as the lectotype. His collaborator Ferdinand Bauer, the botanist and master illustrator, produced artworks to accompany Brown's descriptions, but these were not published until 1838.[7]

In 1983 a species of palm from Somalia was formally transferred to the genus by John Dransfield and Natalie Whitford Uhl.[3]

The Australian members of the genus were subjected to a taxonomic revision by Tony Rodd in 1998. Rodd added five new Australian species, increasing the size of the genus.[7] Another species was described from Vietnam in 2000. In 2009 John Leslie Dowe published the latest monograph on the genus. Along with the Indonesian botanist Johanis P. Mogea and Anders Sánchez Barfod from Denmark, he had described five new species in the previous years, further swelling the genus.[3]

For much of the history of the genus, the species of the genus Saribus were classified within the genus Livistona. Phylogenetic studies using DNA comparisons of numerous species in the different genera in the Trachycarpeae tribe of palms, however, found that the species from the Philippines, New Guinea and other surrounding regions were more closely related to Pholidocarpus, Licuala and Johannesteijsmannia than they were to Livistona, which advocated separating the two groups taxonomically. The genus was thus revised again by Christine D. Bacon and William J. Baker in 2011, with Saribus split off and combined with Pritchardiopsis jeanneneyi, decreasing the genus again.[8]

Etymology

edit

Robert Brown named the genus Livistona after Patrick Murray (1634–1671), Baron of Livingston, a botanist and horticulturist, who was largely responsible for establishing the botanical gardens in Edinburgh, Scotland.[9][10][11] Brown's praise for the early horticulturist begins, "… in memoriam viri nobilis Patricii Murray Baronis de Livistone,", and the Latinised name of the genus is evidently derived from the name of the family's seat.[7]

Distribution

edit

The genus has a disjunct distribution, which is split into three contiguous areas. The range of Livistona carinensis in Africa is very far away from that of the other species in the genus. In 1983 John Dransfield and Natalie Whitford Uhl first suggested that this odd pattern was due to a formerly much more extensive distribution during the warmer and moister climate of the Miocene, including areas between it and the rest, but that prehistoric climate change split them. Later DNA evidence of a mass of ancient extinctions between L. carinensis and the rest is thought to corroborate the theory. The recognition of Saribus has split the remaining distribution into a group of species found in Australia and southern New Guinea, and another group of species in East and Southeast Asia.[8]

Species

edit

The classification of the genus has been the subject of a number of recent revisions which have reduced the number of species since the 2009 monograph. The following is an uncritical list of species:

Ecology

edit

Livistona species are used as food plants by the larvae of some Lepidoptera species. In Australia, the species Cephrenes trichopepla and C. augiades sperthias have been recorded on a number of different Livistona species. In Asia, Elymnias hypermnestra and likely Gangara thyrsis feed on Livistona. A number of other Lepidoptera which do not naturally occur to the native range of the genus Livistona have been recorded feeding on these palms,[13] including Batrachedra arenosella (recorded on L. subglobosa),[citation needed] Brassolis astyra astyra, Opsiphanes cassina, O. invirae and Paysandisia archon.[13]

P. archon is a giant day-flying moth of which the caterpillars known to attack the piths of a number of these palm species, along with many other genera, at least in Europe, where neither the moth nor palms are native. It can kill the palm. It prefers genera of palm with more hairy trunks like Trachycarpus, Trithrinax or Chamaerops.[14]
