Aphandra
''Aphandra'' is a monotypic genus of flowering plants in the palm family native to the Amazon rainforest vegetation in South America (Ecuador, Brazil, and Peru). Its only species is ''Aphandra natalia'', sometimes called mastodon palm or fiber palm, and is used by indigenous peoples in the construction of brooms and other products.Riffle, Robert L. and Craft, Paul (2003) ''An Encyclopedia of Cultivated Palms''. Portland: Timber Press. / (Page 250) This plant is commercially exploited for its edible fruits, and for its leaf sheath and petiole fibers. This fiber is almost equal to the fiber extracted from '' Attalea funifera'' and '' Leopoldinia piassaba'', which is called piassava. The genus name is a combination of '' Ammandra'' and ''Phytelephas'', two closely related palm genera, and the epithet "''natalia''" honors Natalie Uhl, modern palm taxonomist. Description ''Aphandra natalia'' grows from single trunks, reaching over 12 m in height, being gray to tan in color. These tr ...

Ceroxyloideae
The Ceroxyloideae are a subfamily of flowering plants in the Arecaceae, palm family found mainly in the Americas with an outlying genus in each of Australia, Madagascar, and the Comoros. Recently revised, the former subfamily Phytelephantoideae was reduced to the tribal level and included, while the Hyophorbeae tribe was reassigned to Arecoideae; it now contains eight genera. Description From small to moderate to the Ceroxylon quindiuense, tallest in the family, the trunks may be solitary or clustering and lack armament. The reduplicate leaf is regularly or irregularly pinnate, bifid, or entire with pinnate ribs; crownshafts are present in some members and absent in others. Monoecious, Dioecy, dioecious, and hermaphroditic palms occur in the group; a protective prophyll accompanies the inflorescence, and all feature peduncular bracts. Any unisexual flowers are slightly dimorphic, solitary, or in rows; all have syncarpous, triovulate gynoecium.Riffle, Robert L. and Craft, Paul (2 ...

Ammandra
''Ammandra'' is a monotypic genus of flowering plants in the palm family found in Colombia and Ecuador, where it is endangered. The sole species is ''Ammandra decasperma'', although another species name has been proposed. It is a pinnate-leaved, dioecious palm whose seeds and petioles are used in button and basket making, respectively. It is commonly called ivory palm or cabecita. Description ''Ammandra decasperma'' grows in multi-headed clusters, the trunks usually remaining underground or prostrate upon it. Despite the negligible trunk size, the leaves reach over 6 m long, slightly arching, on 2 m petioles. The linear leaflets are dark green, 60–90 cm long, and emerge from the rachis in the same plane. In male plants, the inflorescence is a long spike covered in short branches of white to yellow flowers, the female's being much shorter and more compact. The round fruit grows in clusters of 3-6 and is covered in pointed warts, each fruit containing six or more kidney s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anders S
Anders is a male name in Scandinavian languages and Fering North Frisian, an equivalent of the Greek Andreas ("manly") and the English Andrew. It originated from Andres via metathesis. In Sweden, Anders has been one of the most common names for many centuries, earliest attested in 1378. It was common for priests and farmers during medieval times. According to Statistics Sweden, as of 31 December 2021 it ranks 4th among the male names. The great frequency of this name at the point in time (around 1900) when patronymics were converted into family names is the reason why 1 out of every 30 Swedes today is called Andersson. The name day of Anders in the Scandinavian calendar is 30 November, and in the old peasant superstition that day was important for determining what the Christmas weather would be. If it was very cold on 30 November there would be much sleet on Christmas (and vice versa). In Denmark Donald Duck's name is ''Anders And''. The Fering name Anders may have been bor ...

Piassava
Piassava, also piaçava (), piaçaba (), piasaba, pissaba, piassaba, and piaçá (),The piaçá form occurs mostly in Portugal and is considered less correct by some dictionaries. is a fibrous product of Brazilian palm species '' Attalea funifera'' and '' Leopoldinia piassaba''. It is often used in making brooms and for other purposes. Piassava was historically exported to Europe before the widespread use of synthetic materials such as plastic. Today, it is mostly used locally in South America.

Trees Of Ecuador
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting Branch, branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only Bark (botany), woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos. Trees are not a Monophyletic group, monophyletic taxonomic group but consist of a wide variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andes
The Andes ( ), Andes Mountains or Andean Mountain Range (; ) are the List of longest mountain chains on Earth, longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long and wide (widest between 18th parallel south, 18°S and 20th parallel south, 20°S latitude) and has an average height of about . The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela. Along their length, the Andes are split into several ranges, separated by intermediate depression (geology), depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, Mérida, Mérida, El Alto, and La Paz. The Altiplano, Altiplano Plateau is the world's second highest after the Tibetan Plateau. These ranges are in turn grouped into three majo ...

Flowers
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same flowe ...

Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), 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. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioecious
Dioecy ( ; ; adj. dioecious, ) is a characteristic of certain species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only the female part of the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. In zoology In zoology, dioecy means that an animal is either male or female, in which case the synonym gonochory is more often used. Most animal species are gonochoric, almost all vertebrate species are gonochoric, and all bird and mammal species are gonochoric. Dioecy may also describe colonies ...

Pinnate
Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, and in patterns of erosion or stream beds. The term derives from the Latin word ''pinna'' meaning "feather", "wing", or " fin". A similar concept is "pectination", which is a comb-like arrangement of parts (arising from one side of an axis only). Pinnation is commonly referred to in contrast to "palmation", in which the parts or structures radiate out from a common point. The terms "pinnation" and "pennation" are cognate, and although they are sometimes used distinctly, there is no consistent difference in the meaning or usage of the two words.Jackson, Benjamin, Daydon; ''A Glossary of Botanic Terms with their Derivation and Accent''.
