Lignotuber
A lignotuber is a woody swelling of the root crown possessed by some plants as a protection against destruction of the plant stem, such as by fire. Other woody plants may develop basal burls as a similar survival strategy, often as a response to coppicing or other environmental stressors. However, lignotubers are specifically part of the normal course of development of the plants that possess them, and often develop early on in growth. The crown contains buds from which new stems may sprout, as well as stores of starch that can support a period of growth in the absence of photosynthesis. The term "lignotuber" was coined in 1924 by Australian botanist Leslie R. Kerr. Plants possessing lignotubers include many species in Australia: ''Eucalyptus marginata'' (Jarrah), '' Eucalyptus brevifolia'' (snappy gum) and '' Eucalyptus ficifolia'' (scarlet gum) all of which can have lignotubers wide and deep, as well as most mallees (where it is also known as a mallee root) and many ''Bank ...

Mallee (habit)
Mallee are trees or shrubs, mainly certain species of eucalypts, which grow with multiple stems springing from an underground lignotuber, usually to a height of no more than . The term is widely used for trees with this growth habit across southern Australia, in the states of Western Australia, South Australia, New South Wales and Victoria, and has given rise to other uses of the term, including the ecosystems where such trees predominate, specific geographic areas within some of the states and as part of various species' names. Etymology The word is thought to originate from the word ''mali'', meaning water, in the Wemba Wemba language, an Aboriginal Australian language of southern New South Wales and Victoria. The word is also used in the closely related Woiwurrung language and other Aboriginal languages of Victoria, South Australia, and southern New South Wales. Overview The term ''mallee'' is used describe various species of trees or woody plants, mainly of the genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequoia Sempervirens
''Sequoia sempervirens'' ()''Sunset Western Garden Book,'' 1995:606–607 is the sole living species of the genus '' Sequoia'' in the cypress family Cupressaceae (formerly treated in Taxodiaceae). Common names include coast redwood, coastal redwood, and California redwood. It is an evergreen, long-lived, monoecious tree living 1,200–2,200 years or more. This species includes the tallest living trees on Earth, reaching up to in height (without the roots) and up to in diameter at breast height. These trees are also among the oldest living things on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner of coastal Oregon within the United States. The name sequoia sometimes refers to the subfamily Sequoioideae, which includes ''S. sempervirens'' along with '' Sequoiadendron'' ( ...

Umbellularia
''Umbellularia californica'' is a large hardwood tree native to coastal forests and the Sierra foothills of California, and to coastal forests extending into Oregon. It is endemic to the California Floristic Province. It is the sole species in the genus ''Umbellularia''. The tree was formerly known as ''Oreodaphne californica''. In Yuki, it is called pōl’-cum ōl. In Oregon, this tree is known as Oregon myrtle, while in California it is called California bay laurel, which may be shortened to California bay or California laurel. It has also been called pepperwood, spicebush, cinnamon bush, peppernut tree, headache tree, mountain laurel, and balm of heaven. The tree's pungent leaves have a similar flavor to bay leaves, though stronger, and it may be mistaken for bay laurel. The dry wood has a color range from blonde (like maple) to brown (like walnut). It is considered an excellent tonewood and is sought after by luthiers and woodworkers. The tree is a host of the pathogen t ...

Banksia
''Banksia'' is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes, and fruiting "cones" and heads. ''Banksias'' range in size from prostrate woody shrubs to trees up to 30 metres (100 ft) tall. They are found in a wide variety of landscapes: sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts. Heavy producers of nectar, ''banksias'' are a vital part of the food chain in the Australian bush. They are an important food source for nectarivorous animals, including birds, bats, rats, possums, stingless bees and a host of invertebrates. Further, they are of economic importance to Australia's nursery and cut flower industries. However, these plants are threatened by a number of processes including land clearing, frequent burning and disease, and a number of species are rare and endangered ...

Dicotyledon
The dicotyledons, also known as dicots (or, more rarely, dicotyls), are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this group. The other group of flowering plants were called monocotyledons (or monocots), typically each having one cotyledon. Historically, these two groups formed the two divisions of the flowering plants. Largely from the 1990s onwards, molecular phylogenetic research confirmed what had already been suspected: that dicotyledons are not a group made up of all the descendants of a common ancestor (i.e., they are not a monophyletic group). Rather, a number of lineages, such as the magnoliids and groups now collectively known as the basal angiosperms, diverged earlier than the monocots did; in other words, monocots evolved from within the dic ...

Big Lagoon (California)
Big Lagoon is the southernmost and largest of three similar lagoons within Humboldt Lagoons State Park, along the coast of Humboldt County, California. It is located between Trinidad to the south and Orick at the mouth of Redwood Creek to the north. The lagoons are shallow bays between rocky headlands where coastal wave action has formed a sandy bar separating each lagoon from the Pacific Ocean. The lagoons are resting areas for migratory waterfowl using the Pacific Flyway between Lake Earl on the Smith River estuarine wetlands to the north and Humboldt Bay on the Mad River estuarine wetlands to the south. Geology Big Lagoon is similar to other coastal features of northern California including Humboldt Bay to the south and Lake Earl to the north; an alluvial plain is surrounded by steep uplands. Hills adjacent to Big Lagoon have been identified as the Franciscan Assemblage along the eastern shore and Pleistocene dune sandstone to the south. Studies around Humboldt Ba ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...
