Chamaedorea  Willdenow 1806 Name: Greek chamai = on the ground + dorea = gift  The genus Chamaedorea includes 107 species of small to medium-sized palms with slender bamboo-like stems. The branching yellow sprays of flowers are followed by edible small orange-brown fruits on the female palms. Subfamily Ceroxyloideae has small to medium-sized flowers, spirally arranged, with a gynoecium of three joined carpels. have the largest leaves of any plant, up to 25 m long and 3 m wide. [25] The date palm had a tremendous effect on the history of the Middle East. Preparation of a global action plan for palm conservation began in 1991, supported by the IUCN, and was published in 1996.[35]. Washingtonia  H. Wendland 1879 The genus Washingtonia includes 2 species of fan palm trees native to South-Western North America. Phoenix theophrastii  Greuter 1967 (Cretan Date Palm, Theophrastus' Palm) Named for: Greek natural philosopher Theophrastus of Eresos ca. PLoS ONE 10(4): e0119248.

Some species commonly called palms, though they are not true palms, include: Family of flowering plants known as palms, Not to be confused with the heather family, "Palm tree" redirects here. The stamens generally number six, with filaments that may be separate, attached to each other, or attached to the pistil at the base. However, several factors make palm conservation more difficult. New leaves emerge through a fibrous sheath, which remains attached for a while to the base of the long, smooth, thin petioles and the main stem. The fruit is considered edible. A variety formerly known as C. erumpens has much wider leaflets. C Chemical and molecular data from non-organelle DNA, for example, could be more effective for studying palm phylogeny.[20]. [5], The word Arecaceae is derived from the word areca with the suffix "-aceae". Areca vestiaria  Giseke 1792 (Orange Crownshaft Palm, Sunset Palm, Red Pinang) This colourful slow-growing palm tree has a crownshaft and petioles ranging in colour from red to bright orange. Livistona  R. Brown 1810 Named for: Patrick Murray, Baron of Livistone whose home and collection are the present Royal Botanic Garden, Edinburgh. The stems are decorated with persistent leaf bases and felted with fibrous material. Named for: German orchid collector Carl Roebelen (1855-1927) who discovered this palm in Laos. Probably native to humid forests of Fiji and Tongo, but common cultivation as an architectural plant has obscured its exact origin. Hyophorbe lagenicaulis is native to the Indian ocean islands of Round Island where the species is critically endangered, and Mauritius Island where it survives in parks and gardens. This palm tree has a rough, unbranched 50ft trunk felted with persistent fibrous leaf sheaths which insulate it against cold. This distinguises small plants from the rather similar Chamaerops fortunei which has spiny petioles. As with many cultivated plants, the exact origin of the Betel Nut Palm is obscure but probably Malaysia or the Philippines. We constructed a manually filtered dataset of >20,000 georeferenced Arecaceae records, by eliminating cultivars. These palm trees vary in height from 20 - 130ft and have fan-shaped leaves with smooth petioles. Palms rarely reproduce after such great changes in the habitat, and those with small habitat ranges are most vulnerable to them. "A Molecular Phylogenetic Study of the Palmae (Arecaceae) Based on atpB, rbcL, and 18S nrDNA Sequences". Members of this genus range from 4ft to over 30ft tall. The sap was obtained by cutting down the tree, removing the crown, placing the trunk on a slope and allowing the sap to drip out of the cut end, producing as much as 90 gallons over a few months. Native to Argentina, Brazil and Uruguay. Vol. The leaves have spiny petioles supporting a rounded fan of many leaflets. This palm suckers freely to form clumps. Jubaea  Kunth 1816 Named for: King Juba II of Mauretania (ca. The fruit is boiled to make preserves or wine and the sugary sap is tapped off from cuts in the trunk, drunk fresh or fermented or boiled to make palm sugar (jaggery). Phoenix canariensis  Chabaud 1882 (Canary Island Date Palm, Palmera Canaria) This large solitary palm tree can grow 130ft tall but is often seen smaller. Trachycarpus fortunei  Wendland 1861  Syn. These are the palms planted along Californian boulevards and beaches e.g. Left: A small Washingtonia robusta outside the Temperate House, Royal Botanic Gardens, Kew, in August 2011. The flowers are generally small and white, radially symmetric, and can be either uni- or bisexual. This is the only palm endemic to Europe, forming the only European palm tree forests. Hyophorbe lagenicaulis  (L. Bailey) H.E. Nypa fruticans  Baron Friedrich von Wurmb 1779 (Mangrove Palm)   A thick rhyzome, creeping underground or below the surface of water, produces up to six pinnate leaves up to 30ft long. Like all monocots, palms do not have the ability to increase the width of a stem (secondary growth) via the same kind of vascular cambium found in non-monocot woody plants. explored subfamily and tribe relationships using chloroplast DNA from 60 genera from all subfamilies and tribes. Other palms live in tropical mountain habitats above 1000 m, such as those in the genus Ceroxylon native to the Andes. The yellow-orange oval fruits contain a single large grooved seed surrounded by fruit pulp that is too thin to be worth eating. Statistically derived mean annual temperature, mean annual temperature range, and CMMT thresholds for the Arecaceae and lower rank subfamilies and tribes reveal large differences in temperature sensitivity depending on lower taxonomic classification. [24], An indication of the importance of palms in ancient times is that they are mentioned more than 30 times in the Bible,[26] and at least 22 times in the Quran.[27]. The globular inflorescence of yellowish female flowers is followed by a ball-like cluster of woody nuts, which when ripe split up and fall into the surrounding water as a method of distribution. MU Phytolith Classification System: Notes and Guidelines for Use Deborah M. Pearsall, Professor Emerita (pearsalld@missouri.edu) Department of Anthropology, University of Missouri, Columbia April 2015 Introduction: The MU Phytolith Classification System The MU phytolith classification system was developed as a desktop identification aid, a [3] Currently 181 genera with around 2,600 species are known,[4] most of them restricted to tropical and subtropical climates. The Romans rewarded champions of the games and celebrated military successes with palm branches. Venice Beach Ca., where their salt-tolerance is a virtue. The slender green stem grows over 20ft tall. Livistona rotundifolia  Martius 1838 (Footstool Palm, Anahaw) Name: Latin rotundus = rounded + folium = leaf  This palm tree has a solitary slender trunk up to 80ft tall with prominent leaf scar rings and covered with fibrous material near its tip. The inflorescences are hanging panicles of small, white, fragrant flowers with male and female flowers on separate plants, probably pollinated by wind. Add extension button. Phoenix reclinata  Jacquin 1809 (Wild Date Palm, Senegal Date Palm) Name: Latin reclinata = bending down, referring to the arching leaves. Only about 130 palm species naturally grow entirely beyond the tropics, mostly in humid lowland subtropical climates, in highlands in southern Asia, and along the rim lands of the Mediterranean Sea. A 75ft palm tree with smaller 3ft petioles supporting 3ft fans of leaflets. Top left, right This splendid 55 ft specimen in the Temperate House, Royal Botanic Gardens, Kew, was grown from a seed planted in 1846. More than two-thirds of palm species live in humid moist forests, where some species grow tall enough to form part of the canopy and shorter ones form part of the understory. While Palms aren't succulent, they are often grown by collectors of cacti and other succulent plants. The fruit normally develops from only one carpel. Dransfield J., Uhl N.W., Asmussen C.B., Baker W.J., Harley M.M., Lewis C.E. August 2011, & same plant wrapped for Winter 2010. The dense inflorescence is followed by small dark brown drupes consisting of a thin layer of edible sweet flesh over a single seed. [16] Cultivation of palms is possible north of subtropical climates, and some higher latitude locals such as Ireland, Scotland, England, and the Pacific Northwest feature a few palms in protected locations and microclimates. Palm trees include many important agricultural plants including Coconut (Cocos nucifera,) Date Palm (Phoenix dactylifera,) Oil Palm (Elaeis guineensis,) True Sago Palm (Metroxylon sagus) and Rattan (Calamus sp.) Flowers are followed by yellowish-brown fruit, dates, with a single large grooved seed surrounded by sweet pulp. Rhapis excelsa  Henry 1930 (Kannon Chiku, Broadleaf Lady Palm) Syn. Learn about Plant Taxonomy. A list of all accepted names in Arecaceae is available in CSV format. Chuniophoenix  Burret 1937 This genus includes two species of palms from South-East Asia: C. hainanensis and C. nana. Chuniophoenix nana does well in a pot and is a good subject for a cool conservatory. Arecaceae. Trachycarpus fortunei is the palm tree most frequently seen in Britain. Phoenix roebelenii is native to South-Eastern Asia including South-Western China, Laos and Vietnam. Native to China and Vietnam. [20], Currently, few extensive phylogenetic studies of the Arecaceae exist. [17] Some species form pure stands in areas with poor drainage or regular flooding, including Raphia hookeri which is common in coastal freshwater swamps in West Africa. The date palm not only provided a concentrated energy food, which could be easily stored and carried along on long journeys across the deserts, it also created a more amenable habitat for the people to live in by providing shade and protection from the desert winds (Fig. The Canary Island Date Palm is widely used as an ornamental plant in countries with warm and Mediterranean climates, even growing in Ireland and Southern England as it will withstand occasional mild frost. Native to Rodriguez Island. Palms inhabit a variety of ecosystems. Many distinct varieties are grown commercially in Iraq, North Africa, Palestine and in the South-Western USA, especially Southern California and Arizona. – acrocomia P: Genus Aiphanes Willd. Howea forsteriana  Beccari 1877 (Kentia Palm) Named for: William Forster (1818-1882), Senator and Premier of New South Wales. (January 2005). Some clones are hermaphrodites. Learn how to systematically describe, name, classify and identify plants. The inflorescence includes both male and female flowers and is followed by edible yellow-brown spherical hard-shelled nuts from which an edible oil can be extracted. The underside of each leaflet is pubescent and lower leaflets morph into sharp spines which are more accessible on this short-growing species. However, many palms, like some other monocots, do have secondary growth, although because it does not arise from a single vascular cambium producing xylem inwards and phloem outwards, it is often called "anomalous secondary growth".[13]. 50 BC - 19 AD). This comprehensive 100-hour course provides a solid foundation in plant taxonomy. The fruit is eaten by some people local to its natural range. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. Flowers are hermaphrodite and are followed by clusters of small orange fruits. Named for: William Forster (1818-1882), Senator and Premier of New South Wales. Pritchardia  H. Wendland 1861 Named for: William T. Pritchard, British consul to the Fiji Islands (1858)  This genus includes at least 27 and probably more, fan palm trees native to tropical Islands (Fiji, Hawaii, Samoa, Tonga Tuamotus) in the Pacific Ocean. Calyptronoma is a genus in the palm family, native to the Greater Antilles.They have pinnately compound leaves with short petioles. Both male and female flowers are produced on the same plant. Chamaedorea metallica  O.F. Cook ex H.E. The harvesting of heart of palm, a delicacy in salads, also poses a threat because it is derived from the palm's apical meristem, a vital part of the palm that cannot be regrown (except in domesticated varieties, e.g. Arecaceae definition is - a family of palms that is coextensive with Palmae or restricted to forms closely related to the areca palm. Named for: Patrick Murray, Baron of Livistone whose home and collection are the present Royal Botanic Garden, Edinburgh. In Judaism, the palm represents peace and plenty, and is one of the Four Species of Sukkot; the palm may also symbolize the Tree of Life in Kabbalah. Many common products and foods are derived from palms. Washingtonia robusta  Wendland 1879 (Mexican Washingtonia).

Those having a tree-like form are called palm trees. The specific name is derived from the Binori Reserve Forest. The trunk supports a substantial leaf crown of up to a hundred 15ft long recurved pinnate silver-grey leaves. Dictionary entry overview: What does Arecaceae mean? 1999). Most species are endemic to Hawaii. Statistics. Two of the species Hyophorbe lagenicaulis (Bottle Palm), Hyophorbe Verschaffeltii (Spindle Palm) are critically endangered in their habitat but are likely to survive through widespread cultivation as architectural plants. Grows up to 20ft tall. Subfamily Arecoideae Griffith Tribe Cocoseae Mart. Several palm genera have both solitary and clustering members. The common name refers to use of the sap boiled down into a syrup (palm honey) or fermented into a beverage (palm wine). Rhapis excelsa is probably native to Southern China and Taiwan, but is known only from cultivation. Native to South-Eastern Mexico where it grows as an understory plant on limestone. Despite appearances, the swollen trunk does not store water and frequent watering is required. [6] Areca is derived from Portuguese, via Malayalam അടയ്ക്ക (aṭaykka), which is from Proto-Dravidian *aṭ-ay-kkāy (“areca nut”). The inflorescence is a panicle of small creamy flowers (male) or yellow-orange (female) with male and female flowers on separate plants. The Arecaceae are of great commercial importance as sources of nuts, edible fruits, starchy foods, oils, fibre, thatch and woods and have been cultivated for thousands of years. Specifically it is the symbol of Krishna's brother, Baladeva. [10] The inflorescence is a spadix or spike surrounded by one or more bracts or spathes that become woody at maturity. Chamaerops have spiny petioles whereas those of Trachycarpus have two rows of very small teeth. Along with dates mentioned above, members of the palm family with human uses are numerous. Flowers are followed by large clusters of small blue fruit. Male and female flowers are on separate plants, but male plants are rare in cultivation. Native to the Moluccas Islands near to the coast of Indonesia and requires constantly moist soil, warmth and shade. The common representation is that of a solitary shoot ending in a crown of leaves.

The website also provides access to a database and images of herbarium specimens found at the University of South Florida and other herbaria. This is a small palm tree with a slender trunk up to 50ft tall, usually suckering at its base. When the leaf-sheaths fall a dark green stem, conspicuously ringed with leaf base scars is exposed. Moore (Bottle Palm) Name: Greek lagen = flask + caulis = stem  This slow-growing palm tree develops a swollen, smooth grey lower trunk marked with ring scars. The tolerance of Rhapis excelsa to poor light, low humidity and cold makes it common in shops and offices. Native to Southern Japan, Taiwan and the Ryukyu Islands. [14] The coco de mer (Lodoicea maldivica) has the largest seeds of any plant, 40–50 cm in diameter and weighing 15–30 kg each (coconuts are the second largest). Cabbage Palm, Palm Lily (Cordyline sp. Cal [12] This explains the cylindrical shape of the trunk (almost constant diameter) that is often seen in palms, unlike in ring-forming trees. Chewing betel nuts stains the teeth red and is a significant cause of oral cancer among users. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. Ceroxylon quindiuense, Colombia's national tree, is the tallest monocot in the world, reaching up to 60 m tall. The rarest palm known is Hyophorbe amaricaulis. Class: Liliopsida – Monocotyledons Subclass: Arecidae Order: Arecales Family: Arecaceae ⁄ Palmae – Palm family Genus: Areca L. – areca palm Livistonia palm trees are commonly used for landscaping. It tolerates fresh water but will not grow in undiluted sea water and hence can not be considered a true Mangrove. Most palm seeds lose viability quickly, and they cannot be preserved in low temperatures because the cold kills the embryo.
