Notelaea Sandwicensis
''Notelaea sandwicensis'', commonly known as Hawai'i olive or ''olopua'', is a species of flowering tree in the olive family, Oleaceae, that is endemic to Hawaii. It is found on all major islands at elevations of in coastal mesic and mixed mesic forests, and, especially, dry forests. It usually reaches a height of with a trunk diameter of , but may reach in height with a trunk diameter of . Uses Native Hawaiians used the hard wood of ''olopua'' to make ''au koi'' (adze handles), ''apuapu'' (rasps for making fish hooks), ''ōō'' (digging sticks), ''lāau melomelo'' (fishing lures), ''pou'' (house posts), ''pāhoa'' (daggers), ''pīkoi'' (tripping weapons similar to a rope dart), and spears. Because the wood burned well even if green, it was used as ''wahie'' (firewood Firewood is any wooden material that is gathered and used for fuel.

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botany, botanist of the 19th century. His ''Darwiniana'' (1876) was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built a ...

Rasp
A rasp is a coarse form of file used for shaping wood, metal, or other material. Typically a hand tool, it consists of a generally tapered rectangular, round, or half-round sectioned bar of case hardened steel with distinct, individually cut teeth. A narrow, pointed tang is common at one end, to which a handle may be fitted. Uses Rasps come in a variety of shapes—rectangular, round, and half-round—and vary in coarseness, from finest, "cabinet", to most coarse, "wood". Farriers, for example, commonly use rasps to remove excess wall from a horse's hoof. They are also used in woodworking for rapidly removing material and are easier to control than a drawknife. The rough surfaces they leave may be smoothed with finer tools, such as single- or double-cut files. Rasps are used in shaping alabaster. Saws and chisel A chisel is a hand tool with a characteristic Wedge, wedge-shaped cutting edge on the end of its blade. A chisel is useful for carving or cutting a h ...

Trees Of Hawaii
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] |
Endemic Flora Of Hawaii
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Notelaea
''Notelaea'' is a genus of flowering plants in the family Oleaceae. It includes 21 species native to eastern Australia and Tasmania, New Zealand, the Norfolk Islands, New Caledonia, and the Hawaiian Islands. Plants in the genus ''Notelaea'' are shrubs or small trees with leaves arranged in opposite pairs, flowers arranged in racemes in leaf axils with small sepals and 2 pairs of petals joined in pairs, 2 stamens and an ovary with 2 ovules with a 2-lobed stigma. Description Plants in the genus ''Notelaea'' are shrubs or small trees with simple, leathery leaves arranged in opposite pairs. The flowers are bisexual arranged in racemes in leaf axils, sometimes reduced to sessile clusters. The sepals are small, joined at the base with 4 triangular lobes and the 4 petals are broadly egg-shaped and joined in pairs at the base of the stamens. Each flower has 2 stamens with a flask-shaped ovary with 2 locules each with 2 ovules. The style is short with a 2-lobed stigma and the fruit i ...

Firewood
Firewood is any wooden material that is gathered and used for fuel. Generally, firewood is not heavily processed, and is in some sort of firelog, recognizable log or branch form, compared to other forms of wood fuel like pellet fuel, pellets. Firewood can be seasoned and heat treated (dry) or unseasoned (fresh/wet). It is generally classified as either hardwood or softwood. Firewood is a renewable resource. However, demand for this fuel can outpace its ability to regenerate on a local or regional level. Good forestry practices and improvements in devices that use firewood can improve local wood supplies. Smoke from fire created by burning wood causes respiratory and other diseases. Moreover, transporting firewood long distances can potentially spread plant pests/diseases and invasive species. History For most of human history, firewood was the main fuel, until the use of coal spread during the Industrial Revolution. As such, access to firewood was a valued resource, with E ...

Spear
A spear is a polearm consisting of a shaft, usually of wood, with a pointed head. The head may be simply the sharpened end of the shaft itself, as is the case with Fire hardening, fire hardened spears, or it may be made of a more durable material fastened to the shaft, such as bone, flint, obsidian, copper, bronze, iron, or steel. The most common design for hunting and/or warfare, since modern times has incorporated a metal spearhead shaped like a triangle, lozenge (shape), diamond, or Glossary of leaf morphology, leaf. The heads of fishing spears usually feature multiple sharp Tine (structural), points, with or without barbs. Spears can be divided into two broad categories: those designed for thrusting as a melee weapon (including weapons such as lances and Pike (weapon), pikes) and those designed for throwing as a ranged weapon (usually referred to as javelins). The spear has been used throughout human history as a weapon for hunting and/or fishing and for warfare. Along with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rope Dart
The rope dart or rope javelin (, Japanese: 縄鏢 or 縄標: Jōhyō), is one of the flexible weapons in Chinese martial arts. Other weapons in this family include the meteor hammer, flying claws, and chain whip. It consists of a metal spike attached to the end of a long rope. History The earliest known reference to the rope dart as a distinct weapon from the meteor hammer or flying claw is a drawing in a 19th-century book about street vendors in Beijing. The context and items in this drawing as well as photographs from the early 20th century of similar content suggest these rope darts are intended for use in performance art. These early versions are shown with bamboo tubes that function as a sliding handle. Usage Rope dart play consists of spinning, shooting, and retrieval. One end of the rope, usually a loop or slipknot, is held in or tied to the non-dominant hand to serve as an anchor, while the dominant hand is used to guide the rope, often moving along the length.

Dagger
A dagger is a fighting knife with a very sharp point and usually one or two sharp edges, typically designed or capable of being used as a cutting or stabbing, thrusting weapon.State v. Martin, 633 S.W.2d 80 (Mo. 1982): This is the dictionary or popular-use definition of a dagger, which has been used to describe everything from an ice pick to a folding knife with a pointed blade as a 'dagger'. The Missouri Supreme Court used the popular definition of 'dagger' found in Webster's New Universal Dictionary ("a short weapon with a sharp point used for stabbing") to rule that an ordinary pointed knife with a four- to five-inch blade constitutes a 'dagger' under the Missouri criminal code.California Penal Code 12020(a)(24):"dagger" means a ''knife or other instrument'' with or without a handguard that is ''capable of ready use as a stabbing weapon'' that may inflict great bodily injury or death. The State of California and other jurisdictions have seized upon the popular-use definition of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
