Cyanea Recta
''Cyanea recta'' is a rare species of flowering plant in the bellflower family known by the common names upright cyanea and Kealia cyanea. It is endemic to Hawaii, where it is known only from the island of Kauai.USFWS''Cyanea recta''.The Nature Conservancy. It is a federally listed threatened species of the United States. Like other '' Cyanea'' it is known as ''haha'' in Hawaiian. A 1998 survey estimated up to 1500 individuals remaining in seven populations. These are in a few locations on Kauai, including the Makaleha Mountains. By 2008 one population apparently contained "several thousand" plants.USFWS''Cyanea recta'' Five-year Review.August 2010. This Hawaiian lobelioid is a shrub growing up to 1.5 meters tall. The inflorescence bears purple-striped white or solid purple flowers. It grows in wet forest habitat in the understory of ''ʻōhiʻa lehua'' (''Metrosideros polymorpha''). The habitat In ecology, the term habitat summarises the array of resources, physic ...

Heinrich Wawra Von Fernsee
Heinrich Wawra Ritter von Fernsee, born Jindřich Blažej Vávra, (February 2, 1831 in Brno, Moravia – May 1887 in Baden bei Wien) was a Czech-Austrian ship surgeon, botanist and explorer. The youngest of five sons of a miller, he studied medicine and botany at the University of Vienna from 1849 to 1855. Upon graduating he joined the Austro-Hungarian Imperial Navy on December 6, 1855. The commander of the fleet at this time was the Archduke Ferdinand Maximilian. Wawra von Fernsee retired from the navy in 1878 to work on his extensive collections. The plant genus '' Fernseea'' was named after him.Genaust, Helmut (1976).

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the 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. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Clidemia Hirta
''Miconia crenata'', (syn. ''Clidemia hirta''), commonly called soapbush, clidemia or Koster's curse, is a perennial shrub. It is an invasive plant species in many tropical regions of the world, creating serious damage. Description ''Miconia crenata'' is a densely branching perennial shrub normally growing 0.5–3 m tall, but sometimes growing 5 m tall, depending on habitat. The branchlets are covered in large, stiff, brown or reddish-colored hairs. The simple leaves are oppositely arranged, oval-shaped in outline with a broad base, pointed tips, and almost entire to crenate or finely toothed margins. The leaves are also sparsely covered in hairs above, while more densely hairy beneath; and also have five distinct veins that run in an almost parallel fashion from the leaf bases to their tips. The flowers are arranged in small clusters at the tips of the branches. Each flower has five white, or occasionally pale pinkish, petals and five distinctive stamens that have a claw-like a ...

Erechtites Valerianifolius
''Erechtites valerianifolius'', common name tropical burnweed is a New World species of plants in the sunflower family. It is native to Mexico, Central America, South America, and the West Indies. It is also naturalized as a weed in much of the tropical Old World. Description ''Erechtites valerianifolius'' is an annual herb up to 100 cm (40 inches) tall. Leaves have long petioles with narrow wings along the sides, bearing oblong or elliptical blades with many pinnate lobes. One plant can produce many yellow or purple flower heads, each with both disc floret The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales.

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feral Pig
The feral pig is a domestic pig which has gone feral, meaning it lives in the wild. They are found mostly in the Americas and Australia. Razorback and wild hog are Americanisms applied to feral pigs or boar-pig hybrids. Definition A feral pig is a domestic pig that has escaped or been released into the wild, and is living more or less as a wild animal, or one that is descended from such animals. Zoologists generally exclude from the ''feral'' category animals that, although captive, were genuinely wild before they escaped. Accordingly, Eurasian wild boar, released or escaped into habitats where they are not native, such as in North America, are not generally considered feral, although they may interbreed with feral pigs. Likewise, reintroduced wild boars in Western Europe are also not considered feral, despite the fact that they were raised in captivity prior to their release. In the New World North America Domestic pigs were first introduced to the Americas in the 16th cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrosideros Polymorpha
''Metrosideros polymorpha'', the ''ōhia lehua'', is a species of flowering evergreen tree in the myrtle family, Myrtaceae, that is endemic to the six largest islands of Hawaii. It is a highly variable tree, being tall in favorable situations, and a much smaller prostrate shrub when growing in boggy soils or directly on basalt. It produces a brilliant display of flowers, made up of a mass of stamens, which can range from fiery red to yellow. Many native Hawaiian traditions refer to the tree and the forests it forms as sacred to Pele, the volcano goddess, and to Laka, the goddess of hula. Ōhia trees grow easily on lava, and are usually the first plants to grow on new lava flows. It is a common misconception that the word ''ōhia'' is used to refer to the tree and that the word ''lehua'' refers only to its flowers. ''The Hawaiian Dictionary'' (Pukui and Elbert 1986: 199) defines ''lehua'' with these words: "The flower of the ''ōhia'' tree... ''also the tree itself'' mphasis ...

Understory
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Hillebrand
Wilhelm or William Hillebrand (November 13, 1821 – July 13, 1886) was a German physician. He practiced medicine in several different countries, including for over 20 years in the Hawaiian islands. In 1850, Hillebrand lived at what is now Foster Botanical Garden in Honolulu and gained acknowledgement as a botanist. Life and career Hillebrand was born on November 13, 1821, in Nieheim, Province of Westphalia, Prussia. His father was Judge Franz Josef Hillebrand, and mother Louise Pauline Konig. He studied medicine at Heidelberg and Berlin, and practiced at Paderborn. He sought a warmer climate to recover from a lung problem, (perhaps tuberculosis), first traveling to Australia in 1849, and then the Spanish East Indies, Philippines. Hillebrand then went to San Francisco and finally arrived in the Kingdom of Hawaii, Hawaii on December 22, 1850. He stayed for a little over 20 years and made significant contributions to local medical practice. He was able to speak the Hawaiian langu ...

Hawaiian Lobelioids
The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, subfamily Lobelioideae, all of which are endemic to the Hawaiian Islands. This is the largest plant radiation in the Hawaiian Islands, and indeed the largest on any island archipelago, with over 125 species. The six genera involved can be broadly separated based on growth habit: ''Clermontia'' are typically branched shrubs or small trees, up to tall, with fleshy fruits; ''Cyanea'' and ''Delissea'' are typically unbranched or branching only at the base, with a cluster of relatively broad leaves at the apex and fleshy fruits; ''Lobelia'' and ''Trematolobelia'' have long thin leaves down a single, non-woody stem and capsular fruits with wind-dispersed seeds; and the peculiar ''Brighamia'' have a short, thick stem with a dense cluster of broad leaves, elongate white flowers, and capsular fruits. The relationships among the genera and sections remains unsettled . Many species have beauti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
