A large, very high liana, or "climbing tree" [3] in the palm family, Korthalsia laciniosa occurs in the closed forests of Java, Sumatra, the Philippines, Malay Peninsula, Vietnam, Cambodia and elsewhere in Indochina, and the Nicobar and Andaman Islands. [3]

Habitat

The palm usually grows in lowland forests, often close to the coast, however on the Malay peninsula it has been observed growing in hill Dipterocarp forests up to 1000m elevation. [2] It has been recorded from in the seasonal tropical forests of Cát Tiên [4] and Bạch Mã National Parks in Vietnam, where it occurs in clumps of 4 to 20 individual stems, up to 7.2m long. [5] It is described as a common species in the Andaman Islands, growing in the moist semi-evergreen and deciduous forests belt. [6] Senthilkumar et al. [7] however found it abundant in South Andaman, less common in Middle and North Andaman, and not common in the Nicobar Islands (where it is found in littoral and peripheral forest communities).

Uses

K. laciniosa is known as mây tầm võng [8] in Vietnam (mây is common to many rattans, including more common and numerous Calamus species; [4] [8] other names such as mây ra may be used locally). Before 1990 it was harvested for markets, however in 2005 it was only used locally in Bạch Mã: harvested when the stems are 10-15mm diameter, and so allowing the clumped palm to grow the height given above. [5]

In Cambodia, there is demand for the plant to make ropes and baskets, it is known as phdau saôm or phdau soë:ng (in Khmer phdau="rattan"). [3]

In the Andaman & Nicobar Islands, rattan are integral materials to the livelihood of the inhabitants, this includes K. lacioniosa, known as rassi beth or rope beth. [7] Small diameter canes are used to make fences and rafts, the same and the leaves are used for decorative purposes (such as tables and benches), especially during rituals and ceremonies of the Nicobarese. There is also a substantial export trade of rattan, with K. laciniosa highly valued yet only exported in small quantities. An earlier report on Korthalsia in the Andamans [6] describes K. laciniosa as giving a robust and durable cane, occasionally used to make cane-chair frameworks, but becoming locally scarce in places on South Andaman due to over-extraction.

Rattan, also spelled ratan, is the name for roughly 600 species of Old World climbing palms belonging to subfamily Calamoideae. The greatest diversity of rattan palm species and genera are in the closed-canopy old-growth tropical forests of Southeast Asia, though they can also be found in other parts of tropical Asia and Africa. Most rattan palms are ecologically considered lianas due to their climbing habits, unlike other palm species. A few species also have tree-like or shrub-like habits.

<span class="mw-page-title-main">Nicobar pigeon</span> Species of bird

The Nicobar pigeon or Nicobar dove is a bird found on small islands and in coastal regions from the Andaman and Nicobar Islands, India, east through the Indonesian Archipelago, to the Solomons and Palau. It is the only living member of the genus Caloenas alongside the extinct spotted green pigeon and Kanaka pigeon, and is the closest living relative of the extinct dodo and Rodrigues solitaire.

<i>Canarium</i> Genus of trees

Canarium is a genus of about 120 species of tropical and subtropical trees, in the family Burseraceae. They grow naturally across tropical Africa, south and southeast Asia, Indochina, Malesia, Australia and western Pacific Islands; including from southern Nigeria east to Madagascar, Mauritius, Sri Lanka and India; from Burma, Malaysia and Thailand through the Malay Peninsula and Vietnam to south China, Taiwan and the Philippines; through Borneo, Indonesia, Timor and New Guinea, through to the Solomon Islands, Vanuatu, New Caledonia, Fiji, Samoa, Tonga and Palau.

<span class="mw-page-title-main">Nicobar Islands rain forests</span>

The Nicobar Islands rain forests is a tropical moist broadleaf forest ecoregion in the Nicobar Islands, which is part of the Andaman and Nicobar Islands union territory of India. The Nicobar Islands are in the Indian Ocean, lying north of Sumatra and south of the Andaman Islands. The islands are politically part of India, although physically closer to Southeast Asia. Millions of years of isolation from the mainland has given rise to a distinct flora and fauna, including many endemic species.

<i>Aglaia lawii</i> Species of tree in the Meliaceae from Tropical Asia and China

Aglaia lawii is a species of tree in the family Meliaceae. As well as the autonym species, there are two subspecies accepted.

<i>Korthalsia</i> Genus of palms

Korthalsia is a clustering genus of flowering plant in the palm family spread throughout Southeast Asia. It is a highly specialized rattan with some species known to have an intimate relationship with ants, hence the common name ant rattan. High-climbing and armed with spines, the genus is named for the Dutch botanist P. W. Korthals who first collected them from Indonesia.

<i>Myrialepis</i> Genus of palms

Myrialepis is a monotypic genus of flowering plant in the palm family. The single species, Myrialepis paradoxa, is native to Southeast Asia. The genus name is a combination of the Greek words meaning "innumerable" and "scale", a description of the fruit, and the epithet is Latin for "paradox".

Korthalsia rogersii is an endangered endemic rattan species, thought to be extinct from the insular habitat of the Andaman Islands in the Indian Ocean until 1993. Korthalsia rogersii was first described by Odoardo Beccari in 1918 based on two herbarium field specimens collected by C. G. Rogers in 1904 from the South Andaman Island. This species was known only from these two collections until 1993. Sam Mathew and Pakshirajan Lakshminarasinhan were able to find the species again at Chidiyatapu forests of the South Andamans after a gap of about 100 years. Live collections are introduced at Tropical Botanical Garden and Research Institute, Trivandrum, South India.

<i>Nypa fruticans</i> Species of palm

Nypa fruticans, commonly known as the nipa palm or mangrove palm, is a species of palm native to the coastlines and estuarine habitats of the Indian and Pacific Oceans. It is the only palm considered adapted to the mangrove biome. The genus Nypa and the subfamily Nypoideae are monotypic taxa because this species is their only member.

<i>Dipterocarpus obtusifolius</i> Species of tree

Dipterocarpus obtusifolius is a common species of tree in the family Dipterocarpaceae found throughout Southeast Asia, including Andaman Islands, Myanmar, Thailand, Cambodia, Laos and Vietnam.

Climbing palms are genera in the family Arecaceae that grow as lianas. "Initially erect, the slender stems seek out trees for support and climb up into the forest canopy by means of recurved hooks and spines growing on the stem, leaves and inflorescences. In all climbing palms the leaves are pinnate and grow along the stem instead of forming a dense crown. The stems of climbing palms, more often referred to as canes, are solid in contrast to bamboo poles which are almost always hollow." "The majority of climbing palms are also clumping palms [and sympodial], sending out new shoots from [below ground as suckers]." "About 600 species of palms in [16] genera have a climbing growth habit. Most noteworthy is the genus Calamus--the largest genus in the palm family with approximately 350 described species--source of nearly all commercial rattan."
