Cyanea Remyi
''Cyanea remyi'' is a rare species of flowering plant in the bellflower family known by the common name Remy's cyanea. It is endemic to Hawaii, where it is known only from the island of Kauai. It is a federally listed endangered species of the United States. Like other '' Cyanea'', it is known as ''haha'' in Hawaiian. This plant was very poorly known before 1987, with only two specimens ever having been collected, and no more occurrences of the plant seen since 1916. Then, in 1987, the species was rediscovered when a population of up to 50 plants was found next to the Wailua River. This population was decimated by Hurricane Iniki in 1992, leaving few plants alive. In 2000, eight plants were observed, and in 2006 only a single individual remained. In the meantime other small populations were found, but several have since been destroyed in events such as flash floods. A 2010 report estimated as few as 24 individuals divided among three populations. This Hawaiian lobelioid is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Rock
Joseph Francis Charles Rock (1884 – 1962) was an Austrian-American botanist, explorer, geographer, linguist, ethnographer and photographer. Life Josef Franz Karl Rock was born in Vienna, Austria, the son of a steward of a Polish count. As a result of a generally unhappy childhood and his father's determination that he become a priest, Rock set off on a wandering life in late adolescence. After a few precarious years traveling around Europe, he emigrated to the United States in 1905. He eventually ended up in Honolulu, Hawaii, in 1907, where he would remain for 13 years. Although Rock had no tertiary education, a fact about which he was sensitive and often dissembled, he had a remarkable capability for foreign languages; by the time he reached Hawaii he had a reasonable command of more than half a dozen, including Chinese. Hawaii (1907-1920) Initially Rock taught Latin and natural history at Mills College (now known as Mid-Pacific Institute). With little formal background ...

Arecaceae
The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history. Many common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Phaius Tankervilleae
''Phaius tankervilleae'', commonly known as the greater swamp-orchid, swamp lily, swamp orchid, nun's-hood orchid, nun's orchid, veiled orchid, Lady Tankerville's swamp orchid or 鹤顶兰 (he ding lan), is a species of orchid native to areas from Asia to islands in the Pacific Ocean. It has large, pleated leaves and tall flowering stems bearing up to twenty five white, brown, mauve and yellow flowers. It was named for Lady Tankerville who was the first person to make the orchid flower successfully in England. It was the first tropical orchid to flower in England. Description ''Phaius tankervilleae'' is an evergreen, terrestrial herb that has cone shaped or more or less spherical pseudobulbs mostly long and wide. Between two and eight pleated linear to lance-shaped leaves long and wide develop from the pseudobulb. Between ten and twenty five resupinate flowers wide are borne on a flowering stem tall. The flowers are whitish on the outside and reddish brown inside. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 n ... [...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 16t ... [...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] |
Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate ( Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid fe ...

Tetraplasandra
''Tetraplasandra'' is a no longer recognised genus of plants in the ivy family, Araliaceae. They are small to medium trees, (rarely shrubs or large trees) of mesic to wet forests.Porter P. Lowry II. 1990. "Araliaceae", pages 224-237. In: Warren L. Wagner, Derral R. Herbst, and Sy H. Sohmer. ''Manual of the Flowering Plants of Hawaii'', Revised Edition, 1999. Bishop Museum Press: Hololulu Some authors have recognized as many as 19 species in ''Tetraplasandra'',Earl Edward Sherff. 1955. "Revision of the Hawaiian members of the genus ''Tetraplasandra'' A. Gray". ''Fieldiana: Botany'' 29(2):49-142. while others have recognized as few as six. In 2007, the authors of a scientific paper recommended that the genus be divided into nine species.Annemarie Costello and Timothy J. Motley. 2007. "Phylogenetics of the Tetraplasandra Group (Araliaceae) Inferred from ITS, 5S-NTS, and Morphology". ''Systematic Botany'' 32(2):464-477.

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'' mphas ...

Understory
In forestry and ecology, understory (American English), or understorey (Commonwealth English The use of the English language in current and former member countries of the Commonwealth of Nations was largely inherited from British colonisation, with some exceptions. English serves as the medium of inter-Commonwealth relations. Many ...), 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 broadleaf and mixed forest, temperate deciduous forests, many understory plants start into growth earlier in the year ...
