Araucaria heterophylla
Species of conifer in the family Araucariaceae

Araucaria heterophylla (synonym A. excelsa) is a species of conifer. As its vernacular name Norfolk Island pine (or Norfolk pine) implies, the tree is endemic to Norfolk Island, an external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia. It is not a true pine, which belong to the genus Pinus in the family Pinaceae, but instead is a member of the genus Araucaria, in the family Araucariaceae, which also contains the monkey-puzzle tree. Members of Araucaria occur across the South Pacific, especially concentrated in New Caledonia (about 700 km or 430 mi due north of Norfolk Island) where 13 closely related and similar-appearing species are found. It is sometimes called a star pine, Polynesian pine, triangle tree or living Christmas tree, due to its symmetrical shape as a sapling.

Dictyosperma album

Dictyosperma is a monotypic genus of flowering plant in the palm family found in the Mascarene Islands in the Indian Ocean (Mauritius, Réunion and Rodrigues). The sole species, Dictyosperma album, is widely cultivated in the tropics but has been farmed to near extinction in its native habitat. It is commonly called princess palm or hurricane palm, the latter owing to its ability to withstand strong winds by easily shedding leaves. It is closely related to, and resembles, palms in the genus Archontophoenix. The genus is named from two Greek words meaning "net" and "seed" and the epithet is Latin for "white", the common color of the crownshaft at the top of the trunk.

Pritchardia glabrata

Species of palm

Pritchardia glabrata is a species of palm tree. It is endemic to the island of Maui in Hawaii. Pritchardia glabrata is Endemic of Maui, Hawaii islands, USA. It grows at around 500-550 metres A.S.L. It grows on steep slopes between 300 and 900 metres (1000 and 3000 feet) above sea level on the Hawaiian Islands of Maui and Lanai, which are slightly drier.This is one of the small Pritchardia, with a slender trunk rarely reaching five meters (17 feet) in length, but otherwise similar to P. remote and P. waialealeana, with which it shares the same sort of simple trunk.


Roystonea regia
Species of palm

Roystonea regia, commonly known as the Cuban royal palm or Florida royal palm, is a species of palm that is native to Mexico, parts of Central America and the Caribbean, and southern Florida. A large and attractive palm, it has been planted throughout the tropics and subtropics as an ornamental tree. Although it is sometimes called R. elata, the conserved name R. regia is now the correct name for the species. The royal palm reaches heights from 50 to over 80 feet tall. Populations in Cuba and Florida were long seen as separate species, but are now considered a single species.

Quick Facts Royal palm, Conservation status ...
Widely planted as an ornamental, R. regia is also used for thatch, construction timber, and in some forms of so-called traditional medicine, although there is currently no valid scientific evidence to support the efficacy or use of any palm species for medicinal purposes. The fruit is eaten by birds and bats (which disperse the seeds) and fed to livestock. Its flowers are visited by birds and bats, and it serves as a roosting site and food source for a variety of animals. Roystonea regia is the national tree of Cuba, and has a religious role both in Santería and Christianity, where it is used in Palm Sunday observances.
Syagrus macrocarpa
Species of palm

Syagrus macrocarpa is a rare species of palm found only as scattered isolated individuals and small groups in the east of the Brazilian states of Espírito Santo, Minas Gerais and Rio de Janeiro. It grows to 4-10m tall, with 8-20 leaves to 2m long. The leaves are bent at the end, with very hairy margins near the trunk, and consist of 180-320 slightly coiled leaflets irregularly arranged in several planes on the rake. The fruit are oval, greenish-yellow, 6–9 cm long. It is grown in cultivation. Seeds are difficult to germinate, with low rates of germination. Common names for it in Minas Gerais are baba-de-boi-grande and maria-rosa.

Quick Facts Syagrus macrocarpa, Conservation status ...
Unlike most other species of Syagrus, this species started in 1879 as a Syagrus, as João Barbosa Rodrigues classified it along with Karl von Martius' S. cocoides. Three years later Rodrigues synonymised the genus Syagrus with Cocos (it was resurrected in 1916 by Beccari).

It is native to southern Japan, Taiwan, the Ryukyu Islands, southeastern China and Hainan. In Japan, two notable populations occupy islands near the coast of Miyazaki Prefecture, Aoshima and Tsuki Shima. It is also reportedly naturalized in South Africa, Mauritius, Réunion, the Andaman Islands, Java, New Caledonia, Micronesia, Hawaii, Florida, Bermuda, Puerto Rico and the Dominican Republic.
Cryosophila warscewiczii
Species of palm

Cryosophila warscewiczii is a species of flowering plant in the family Arecaceae, endemic to Central America. It is a tree with palmate leaves, growing to 10 meters in height with trunk 10–15 cm. in diameter above its enlarged base. Much of the trunk bears spines transformed from roots.

Bentinckia nicobarica
Species of flowering plant

Bentinckia nicobarica is a species of flowering plant in the family Arecaceae found to occur in the Nicobar group of islands in the Bay of Bengal. It is an endemic palm occurring in Great Nicobar, Katchal, Nancowry and Car Nicobar Islands.

Quick Facts Bentinckia nicobarica, Conservation status ...
The occurrence of this species in Andaman and Nicobar group of islands other than Katchal Island is yet to be confirmed as natural/escape or by human introduction. It is an endangered species according to IUCN Red List of Threatened Species, 2016 with Red List Category & Criteria as C2a (ver 2.3). Living specimens of this taxon are conserved at the Indian Botanic Garden, Howrah and at the Field Gene Bank of Jawaharlal Nehru Tropical Botanic Garden and Research Institute, Thiruvananthapuram in India.

The adult mānuka beetle (Pyronota festiva) and its larvae feed on L. scoparium in New Zealand.

Pollinators

Various pollinators are known to visit L. scoparium, some examples include Melangyna novaezelandiae, Hylaeus, and Honeybees.

Continued evolution

Leptospermum scoparium is in the process of evolutionary differentiation as a result of its isolation from fellow members of the Leptospermum genus. New studies demonstrate a loss of lignotubers among populations of Leptospermum scoparium located in relatively fire-free zones of New Zealand's South Island, while Australian and Tasmanian populations retain their lignotubers along with stronger manifestations of serotiny. Australian populations of Leptospermum scoparium are shown to be chemically distinct from their New Zealand counterparts, with significantly higher levels of cinteole and monoterpines. Chemotypical variations also exist between different populations within New Zealand, leading some to suggest that L. scoparium be divided into three subspecies: those with high pinenes, high triketones, and high sesquiterpenes. Recently, however, new research suggests that plant-to-plant variation far outstrips the variation seen between geographically isolated manuka sites, at least with regard to nectar chemistry.

Names

Mānuka, tea tree and kāhikatoa are common names for this species. "Jelly bush" is also used in Australia to describe similar honey from Leptospermum polygalifolium. Tea tree arose because Captain Cook used the leaves to make a 'tea' drink.

Mānuka is a Māori word from New Zealand.

Cultivation

Numerous cultivars have been developed for garden use, of which the following have gained the Royal Horticultural Society's Award of Garden Merit:

(Nanum Group) 'Kiwi''Nichollsii Nanum''Red Damask''Silver Sheen'

Many more cultivars are available in New Zealand but often the plant performs better in cultivation overseas. This is because in its homeland it is subject to attack by scale insects that secrete a honeydew on which grows a sooty mould that eventually debilitates the plant. Because of this, attempts have been made, with limited commercial success, to cross the showy New Zealand cultivars with mould-resistant Australian Leptospermum species.

Uses

Mānuka (Leptospermum scoparium) essential oil in a clear glass vial

The wood was often used for tool handles. Mānuka sawdust imparts a delicious flavour when used for smoking meats and fish.[citation needed] It is cultivated in Australia and New Zealand for mānuka honey, produced when honeybees gather the nectar from its flowers, and for the pharmaceutical industry. It is also used for carving. An essential oil, for which many medicinal claims are made, is produced by steam distillation of its leaves. Mānuka, as it is called by most New Zealanders, was used in pre-European times by Māori, and still is. A decoction of the leaves was drunk for urinary complaints and as a febrifuge (an agent for reducing fever). The steam from leaves boiled in water was inhaled for head colds. A decoction was prepared from the leaves and bark and the warm liquid was rubbed on stiff muscles and aching joints. The emollient white gum, called pai mānuka, was given to nursing babies and also used to treat scalds and burns. Chewing the bark is said to have a relaxing effect and it enhances sleep.

Açaí palm
Palm tree with many uses, mainly fruit as cash crop

The açaí palm (/əˈsaɪ.iː/, Portuguese: [asaˈi] (listen), from Nheengatu asai), Euterpe oleracea, is a species of palm tree (Arecaceae) cultivated for its fruit (açaí berries, or simply açaí), hearts of palm (a vegetable), leaves, and trunk wood. Global demand for the fruit has expanded rapidly in the 21st century, and the tree is cultivated for that purpose primarily.

Quick Facts Scientific classification, Binomial name ...
The species is native to eastern Amazonia, especially in Brazil, mainly in swamps and floodplains. Açaí palms are tall, slender trees growing to more than 25 m (82 ft) tall, with pinnate leaves up to 3 m (9.8 ft) long. The fruit is small, round, and black-purple in color. The fruit became a staple food in floodplain areas around the 18th century, but its consumption in urban areas and promotion as a health food only began in the mid 1990s along with the popularization of other Amazonian fruits outside the region.

Name
The common name comes from the Portuguese adaptation of the Tupian word ĩwasa'i, meaning "[fruit that] cries or expels water". The importance of the fruit as a staple food in the Amazon River delta gives rise to the local legend of how the plant got its name. The folklore says that chief Itaqui ordered all newborns put to death owing to a period of famine. When his own daughter gave birth and the child was sacrificed, she cried and died beneath a newly sprouted tree. The tree fed the tribe and was called açaí because that was the daughter's name (Iaçá) spelled backwards.

Its specific epithet oleracea means "vegetable" in Latin and is a form of holeraceus (oleraceus).
