Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...

Muehlenbeckia Florulenta
''Duma florulenta'' (synonym ''Muehlenbeckia florulenta''), commonly known as tangled lignum or often simply lignum, is a plant native to inland Australia. It is associated with wetland habitats, especially those in arid and semiarid regions subject to cycles of intermittent flooding and drying out. The Wiradjuri name for the plant is gweeargal, and the Walmajarri name is ''Kirinykiriny'', or ''Kurinykuriny''. Description Lignum is a perennial, monoecious shrub, growing to 2.5 m in height, with its multitude of thin, intertwined and tangled branches and branchlets forming dense thickets to the exclusion of other species. Its thin, narrow leaves are 15–70 mm long and 2–10 mm wide. The grey-green stems often end in a sharp point. The flowers are small and cream to yellowish, solitary or clustered along the branchlets and occurring through most of the year. The fruit is top-shaped, dry, and about 5 mm long.

Lignum Crucis
The True Cross is the cross upon which Jesus was said to have been crucified, particularly as an object of religious veneration. There are no early accounts that the apostles or early Christians preserved the physical cross themselves, although protective use of the sign of the cross was common by at least the 2nd century. Post-Nicene historians such as Socrates of Constantinople relate that Helena, the mother of the Roman emperor ConstantineI, travelled to the Holy Land in the years 326–328, founding churches and establishing relief agencies for the poor. The late 4th-century historians Gelasius of Caesarea and Tyrannius Rufinus claimed that while there she discovered the hiding place of three crosses that were believed to have been used at the crucifixion of Jesus and the two thieves, St. Dismas and Gestas, executed with him. To one cross was affixed the titulus bearing Jesus's name, but according to Rufinus, Helena was not sure until a miracle revealed that this was the ...

Lignum Vitae
Lignum vitae () is a wood, also called guayacan or guaiacum, and in parts of Europe known as Pockholz or pokhout, from trees of the genus ''Guaiacum''. The trees are indigenous to the Caribbean and the northern coast of South America (e.g: Colombia and Venezuela) and have been an important export crop to Europe since the beginning of the 16th century. The wood was once very important for applications requiring a material with its extraordinary combination of strength, toughness, and density. It is also the national tree of the Bahamas, and the Jamaican national flower. The wood is obtained chiefly from ''Guaiacum officinale'' and ''Guaiacum sanctum'', both small, slow-growing trees. All species of the genus ''Guaiacum'' are now listed in Appendix II of CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) as potentially endangered species. ''G. sanctum'' is listed as Near Threatened by the IUCN Red List. Demand for the wood has been reduc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lunsford, Sr. and two other investors in 1953. Charlotte and Russell Neidhauk lived on the island and served as caretakers during this period. The coral Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
