Dypsis is a genus of flowering plants in the family Arecaceae. They are slender, evergreen palms with yellow flowers carried in panicles amongst the pinnate leaves. Many Dypsis species have aerial branching (above the main trunk), a rare growth habit among palms. [2] Some have marcescent leaves that remain attached after death and trap litter for nutrients. [3]

Etymology

The etymology is obscure but may be related to the Greek dypto ‘I dive’ or dyptes ‘diver’. [4] The species are native to Tanzania, Madagascar, and various islands in the Indian Ocean (Mauritius and Comoros). A few are naturalized in other regions, especially in the Caribbean. [1]

<i>Areca</i> Genus of palms

Areca is a genus of 51 species of palms in the family Arecaceae, found in humid tropical forests from the islands of the Philippines, Malaysia and India, across Southeast Asia to Melanesia. The generic name Areca is derived from a name used locally on the Malabar Coast of India.

<i>Phoenix</i> (plant) Genus of flowering plants of the palm family

Phoenix is a genus of 14 species of palms, native to an area starting from the Canary Islands in the west, across northern and central Africa, to the extreme southeast of Europe (Crete), and continuing throughout southern Asia from Turkey east to southern China and Malaysia. The diverse habitats they occupy include swamps, deserts, and mangrove sea coasts. Most Phoenix species originate in semi-arid regions, but usually occur near high groundwater levels, rivers, or springs. The genus is unusual among members of subfamily Coryphoideae in having pinnate, rather than palmate leaves; tribe Caryoteae also have pinnate or bipinnate leaves.

<i>Pritchardia</i> Genus of plants

The genus Pritchardia consists of between 24 and 40 species of fan palms found on tropical Pacific Ocean islands in Fiji, Samoa, Tonga, Tuamotus, and most diversely in Hawaii. The generic name honors William Thomas Pritchard (1829-1907), a British consul at Fiji.

<i>Plumbago</i> Genus of carnivorous plants

Plumbago is a genus of 10–20 species of flowering plants in the family Plumbaginaceae, native to warm temperate to tropical regions of the world. Common names include plumbago and leadwort.

<i>Chamaedorea</i> Genus of palms

Chamaedorea is a genus of 107 species of palms, native to subtropical and tropical regions of the Americas. They are small palms, growing to 0.3–6 m tall with slender, cane-like stems, growing in the understory in rainforests, and often spreading by means of underground runners, forming clonal colonies. The leaves are pinnate, with one to numerous leaflets. The flowers are produced in inflorescences; they are dioecious, with male and female flowers on separate plants. The fruit is an orange or red drupe 0.5–2 cm diameter. Perhaps the best-known species is Chamaedorea elegans from Mexico and Guatemala. It is popular as a houseplant, particularly in Victorian houses. Another well-known species is Chamaedorea seifrizii, the bamboo palm or reed palm.

Marcescence Retention of dead plant organs that normally are shed

Marcescence is the retention of dead plant organs that normally are shed. Trees transfer water and sap from the roots to the leaves through their vascular cells, but in some trees as autumn begins, the veins carrying the sap slowly close until a layer of cells called the abscission layer completely closes off the vein allowing the tree to rid itself of the leaf. Leaf marcescence is most often seen on juvenile plants and may disappear as the tree matures. It also may not affect the entire tree; sometimes leaves persist only on scattered branches. Marcescence is most obvious in deciduous trees that retain leaves through the winter. Trees that exhibit marcescence are known as "everciduous". Several trees normally have marcescent leaves such as oak (Quercus), beech (Fagus) and hornbeam (Carpinus), or marcescent stipules as in some but not all species of willows (Salix). All oak trees may display foliage marcescence, even species that are known to fully drop leaves when the tree is mature. Marcescent leaves of pin oak complete development of their abscission layer in the spring. The base of the petiole remains alive over the winter. Many other trees may have marcescent leaves in seasons where an early freeze kills the leaves before the abscission layer develops or completes development. Diseases or pests can also kill leaves before they can develop an abscission layer.

<i>Butia</i> Genus of palms

Butia is a genus of palms in the family Arecaceae, native to the South American countries of Brazil, Paraguay, Uruguay and Argentina. Many species produce edible fruits, which are sometimes used to make alcoholic beverages and other foods. The name is derived from a Brazilian vernacular word for members of the genus.

<i>Dypsis lutescens</i> Species of plant in the family Arecaceae

Dypsis lutescens, also known as golden cane palm, areca palm, yellow palm, butterfly palm, or bamboo palm, is a species of flowering plant in the family Arecaceae, native to Madagascar and naturalized in the Andaman Islands, Réunion, El Salvador, Cuba, Puerto Rico, the Canary Islands, southern Florida, Haiti, the Dominican Republic, Jamaica, the Leeward Islands and the Leeward Antilles.

<i>Dypsis decaryi</i> Species of plant in the family Arecaceae

Dypsis decaryi is a species of flowering plant in the Arecaceae family. It is commonly known as the triangle palm. It is indigenous to the Madagascan rainforest. Some specimens grow to a height of some 15 metres (49 ft) in the wild. It is relatively new to cultivation however, so outside its native habitat it rarely achieves anything like that height. The leaves are about 2.5 metres in length, growing almost upright from the trunk and arching gracefully outward about a metre from their tips. The leaf bases are arranged in three vertical columns set about 120 degrees apart on the main stem, forming a triangular shape in cross section. This shape has given rise to the palm's common name.

Dypsis canescens, also known as Chrysalidocarpus canescens, is a species of flowering plant in the family Arecaceae. It was identified in 1913 in Madagascar. It is probably extinct, given that it has not been seen for half a century.

<i>Itaya</i> Species of plant

Itaya amicorum is a medium-size fan palm that is native to Brazil, Colombia and Peru. It is the only species in the genus Itaya. It was unknown to science until 1972, when it was discovered on the bank of the Itaya River in the Peruvian Amazon.

Lepidocaryum is a monotypic genus of flowering plant in the palm family from South America where the lone species, Lepidocaryum tenue, is commonly called poktamui. Nine species names have been published, but palm taxonomists currently agree that just one variable species includes them all. The most reduced member of the Lepidocaryeae, it is similar in appearance to three closely related genera, Mauritia, Mauritiella, and Lytocaryum. The genus name combines the Greek words for "scale" and "nut" and the species epithet is Latin for "thin".

Dypsis brevicaulis is a species of flowering plant in the Arecaceae family. It is a dwarf palm found on only three sites in Madagascar, with fewer than fifty plants ever found in the wild. The plant is part of the IUCN Sampled Red List Index for Plants, a study of representative species from all over the world which is studying extinction trends for plants.

Dypsis humilis is a rare species of stemless palm that was discovered in Madagascar in 2007 by a collaboration between botanists from Madagascar and Royal Botanical Gardens, Kew. Fewer than ten plants were observed in an area that is threatened by logging and other human activity.

Cadang-cadang is a disease caused by Coconut cadang-cadang viroid (CCCVd), a lethal viroid of coconut, African oil palm, anahaw, and buri palms. The name cadang-cadang comes from the word gadang-gadang that means dying in Bicol. It was originally reported on San Miguel Island in the Philippines in 1927/1928. "By 1962, all but 100 of 250,000 palms on this island had died from the disease," indicating an epidemic. Every year one million coconut palms are killed by CCCVd and over 30 million coconut palms have been killed since Cadang-cadang was discovered. CCCVd directly affects the production of copra, a raw material for coconut oil and animal feed. Total losses of about 30 million palms and annual yield losses of about 22,000 tons of copra have been attributed to Cadang-cadang disease in the Philippines.

Calamoideae Subfamily of palms

Calamoideae is a subfamily of flowering plant in the palm family found throughout Central America, South America, Africa, India, China, Southeast Asia and Australia. It is represented by 21 genera - containing nearly a quarter of all species in the palm family - including the largest genus, Calamus, the type genus of the group. Only four are found in the New World while the rest are Old World denizens, usually found in equatorial swampland or along tropical coastlines.

<i>Cyrtostachys renda</i> Species of palm

Cyrtostachys renda, also known by the common names red sealing wax palm and lipstick palm, is a palm that is native to Thailand, Malaysia, Sumatra and Borneo in Indonesia. It is the only species of the genus Cyrtostachys that can be found to the west of the Wallace Line, the faunal boundary separating the biogeographic realms of Asia and Wallacea. Cyrtostachys renda's name is derived from several words: the Greek prefix κυρτό- (cyrto-) meaning bent or curved, the Greek word σταχυς (stachys) meaning "an ear of grain", and "renda" a Malayan Aboriginal word for palm, which happens to be homonymous to the Portuguese word "renda," meaning income.

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."

Hemiberlesia lataniae, the latania or palm scale, is a species of armored scale insect in the family Diaspididae. It was first described by the French entomologist Victor Antoine Signoret in 1869 using Latania lontaroides, a species of palm tree endemic to Réunion as its host; since then, it has been found on avocado trees growing in South Africa, Australia, Israel, the United States, and on a range of other plants in many parts of the world.

<i>Dypsis baronii</i> Species of flowering plant

Dypsis baronii is a flowering plant, which is a member of the palm family Arecaceae. It is otherwise known as "sugarcane palm" because of the scars on its trunks that resemble sugarcane.
