Ceiba Chodatii
''Ceiba chodatii'', the floss silk tree, is a species of deciduous tree native to the tropical and subtropical forests of South America. It has a bottle-shaped swollen trunk in which water is stored for the dry season and is known locally as palo borracho. Description ''Ceiba chodatii'' is a medium-sized deciduous tree with a tall, stout, bare trunk. It grows to about tall, has a number of thick branches at the top of the swollen trunk and has a rounded crown. The bark is smooth with vertical ridges and horizontal wrinkles. It contains chlorophyll and is green when young and able to photosynthesize, but turns grey with age. It is covered with thick, woody conical spines. The alternate leaves are palmate with five lobes and serrated edges. The flowers are large, solitary and creamy white with a few purple flecks. They are up to long with yellow-green calyces and funnel-shaped corollas with five fleshy, hairy petals joined at the base. The fruit is a large, oblong green capsule ...

Deciduous
In the fields of horticulture and botany, the term deciduous () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed Leaf, leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their Leaf, leaves for part of the year. This process is called abscission. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canoe
A canoe is a lightweight, narrow watercraft, water vessel, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddlers facing the direction of travel and using paddles. In British English, the term ''canoe'' can also refer to a kayak, whereas canoes are then called Canadian (canoe), Canadian or open canoes to distinguish them from kayaks. However, for official competition purposes, the American distinction between a kayak and a canoe is almost always adopted. At the Olympics, both conventions are used: under the umbrella terms Canoe Slalom and Canoe Sprint, there are separate events for canoes and kayaks. Culture Canoes were developed in cultures all over the world, including some designed for use with sails or outriggers. Until the mid-19th century, the canoe was an important means of transport for exploration and trade, and in some places is still used as such, sometimes with the addition of an outboard motor. Where the canoe play ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Bolivia
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that 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 around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceiba
''Ceiba'' is a genus of trees in the family Malvaceae, native to Tropics, tropical and Subtropics, subtropical areas of the Americas (from Mexico and the Caribbean to northern Argentina) and tropical West Africa. Some species can grow to tall or more, with a straight, largely branchless trunk that culminates in a huge, spreading canopy, and buttress roots that can be taller than a grown person. The best-known, and most widely cultivated, species is Kapok, ''Ceiba pentandra'', one of Kapok (other), several trees known as ''kapok''. ''Ceiba'' is a word from the Taíno language meaning "boat" because Taínos use the wood to build their dugout canoes. ''Ceiba'' species are used as food plants by the larvae of some Lepidoptera (butterfly and moth) species, including the leaf-miner ''Bucculatrix ceibae'', which feeds exclusively on the genus. Recent botanical opinion incorporates ''Chorisia'' within ''Ceiba'' and puts the genus as a whole within the family Malvaceae. Cultu ...

Cereus (plant)
''Cereus'' ( "serious") is a genus of Cactus, cacti (family Cactaceae) including around 33 species of large columnar cacti from South America. The name is derived from Greek language, Greek (κηρός) and Latin words meaning "wax", "torch" or "candle". ''Cereus'' was one of the first cactus genera to be described; the circumscription varies depending on the authority. The term "cereus" is also sometimes used for a ceroid cactus, any cactus with a very elongated body, including columnar growth cacti and epiphytic cacti. Description ''Cereus'' are shrubby or treelike, often attaining great heights (''Cereus hexagonus, C. hexagonus, Cereus lamprospermus, C. lamprospermus, Cereus trigonodendron, C. trigonodendron'', ''Cereus ingens, C. ingens'' up to ).

Microphyll
In plant anatomy and evolution a microphyll (or lycophyll) is a type of plant leaf with one single, unbranched leaf vein. Plants with microphyll leaves occur early in the fossil record, and few such plants exist today. In the classical concept of a microphyll, the leaf vein emerges from the protostele without leaving a leaf gap. Leaf gaps are small areas above the node of some leaves where there is no vascular tissue, as it has all been diverted to the leaf. Megaphylls, in contrast, have multiple veins within the leaf and leaf gaps above them in the stem. Leaf vasculature The clubmosses and horsetails have microphylls, as in all extant species there is only a single vascular trace in each leaf. These leaves are narrow because the width of the blade is limited by the distance water can efficiently diffuse cell-to-cell from the central vascular strand to the margin of the leaf. Despite their name, microphylls are not always small: those of '' Isoëtes'' can reach 25 centimetr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
