Licuala Cattienensis
''Licuala cattienensis'', is a small fan palm, endemic to southern Vietnam. The type locality is in Cát Tiên National Park in Đồng Nai Province, growing in seasonal tropical forest in flat areas near rivers at low elevations. It is recognisable by being much smaller (<2m) and single-stemmed, in comparison the larger '' L. spinosa'', which is common in the Park and grows in grows in clumps. The local name for fan palms is ''mật cật''; the authors also cite ''lá toi''. No uses have been recorded. Description 
The authors describe the plants as having solitary stems (but sometimes with basal shoots), maximum: 2 m tall and 40 mm in diameter. There ar ...

Cát Tiên National Park
Cát Tiên National Park ( vi, Vườn quốc gia Cát Tiên) is a national park located in the south of Vietnam, belonging to the area of 3 provinces Đồng Nai province, Đồng Nai, Bình Phước province, Bình Phước and Lâm Đồng province, Lâm Đồng. It is approximately 150 km north of Ho Chi Minh City. It has an area of about 720 km2 and protects one of the largest areas of lowland tropical forests left in Vietnam. History The surrounding area was originally occupied by the Ma people - especially in the area that is now Cat Loc (in the 1960s eastern Nam Cat Tien was described as "''inhabité'' - uninhabited") and Stieng people in western Dong Nai Province. After the formation of the Park, many of these people were re-settled in Tà Lài, Talai village, to the south-west of Nam Cat Tien. Cát Tiên National Park (CTNP) was protected initially in 1978 as two sectors, Nam Cat Tien and Tay Cat Tien. Another sector, Cat Loc, was gazetted as a rhinocer ...

Monoecious
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is connected to anemophily. It can prevent self-pollination in an individual flower but cannot prevent self-pollination between male and female flowers on the same plant. Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function. Monoecious hemp was first reported in 1929. Occurrence Monoecy is most common in temperate climates and is often associated with inefficient pollinators or wind-pollinated plants. It may be beneficial to reducing pollen-stigma interferenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Licuala
''Licuala'' is a genus of palms, in the tribe Trachycarpeae, commonly found in tropical forests of southern China, Southeast Asia, the Himalayas, New Guinea and the western Pacific Ocean islands. Description and uses ''Licuala'' spp. are fan palms, with the leaves mostly circular in outline, sometimes undivided but more usually divided into wedge-shaped segments. ''Licuala acutifida'' is the source of cane for the walking stick nicknamed the ''Penang-lawyer'' by colonials, probably from the Malay phrase for a wild areca, although the term may also refer to the use of these canes as deadly knobkerries to assassinate litigious enemies. Several species of ''Licuala'' have been transferred into a new genus ''Lanonia''. Species ''Plants of the World Online'' currently (February 2021) includes 167 accepted species: * '' Licuala acuminata'' Burret * ''Licuala acutifida'' Mart. * '' Licuala adscendens'' Barfod & Heatubun * '' Licuala ahlidurii'' Saw * '' Licuala angustiloba'' Burre ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rachis
In biology, a rachis (from the grc, ῥάχις [], "backbone, spine") is a main axis or "shaft". In zoology and microbiology In vertebrates, ''rachis'' can refer to the series of articulated vertebrae, which encase the spinal cord. In this case the ''rachis'' usually forms the supporting axis of the body and is then called the spine or vertebral column. ''Rachis'' can also mean the central shaft of pennaceous feathers. In the gonad of the invertebrate nematode '' Caenorhabditis elegans'', a rachis is the central cell-free core or axis of the gonadal arm of both adult males and hermaphrodites where the germ cells have achieved pachytene and are attached to the walls of the gonadal tube. The rachis is filled with cytoplasm. In botany In plants, a rachis is the main axis of a compound structure. It can be the main stem of a compound leaf, such as in ''Acacia'' or ferns, or the main, flower-bearing portion of an inflorescence above a supporting peduncle. Where it subdivides ...

Inflorescences
An inflorescence is a group or cluster of flowers arranged on a Plant stem, stem that is composed of a main branch or a complicated arrangement of branches. Morphology (biology), Morphologically, it is the modified part of the shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a Peduncle (botany), peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a Pedicel (botany) , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arecaceae
The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history. Many common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their importance as ...
