Paphiopedilum Harrisianum
''Paphiopedilum'', often called the Venus slipper, is a genus of the lady slipper orchid subfamily ''Cypripedioideae'' of the flowering plant family Orchidaceae. The genus comprises some 80 accepted taxa including several natural hybrids. The genus is native to Southeast Asia, the Indian Subcontinent, southern China, New Guinea and the Solomon and Bismarck Islands. The type species of this genus is '' Paphiopedilum insigne''. The species and their hybrids are extensively cultivated, and are known as either paphiopedilums, or by the abbreviation paphs in horticulture. Due to their popularity, Paphiopedilums have been ruthlessly gathered and poached from the wild, making them very rare or extinct there. As soon as a new species or population is discovered, poachers will take the plants for orchid collectors who pay large sums of money. Habitat destruction is an additional factor contributing to their rarity. Description ''Paphiopedilum'' species naturally occur among humus la ...

Bismarck Islands
The Bismarck Archipelago (, ) is a group of islands off the northeastern coast of New Guinea in the western Pacific Ocean and is part of the Islands Region of Papua New Guinea. Its area is about . History The first inhabitants of the archipelago arrived around 30,000–40,000 years ago. They may have traveled from New Guinea, by boat across the Bismarck Sea or via a temporary land bridge, created by an uplift in the Earth's Crust (geology), crust. Later arrivals included the Lapita people, the direct ancestors of the Austronesian peoples of Polynesia, eastern Micronesia, and Island Melanesia. The first European to visit these islands was Dutch explorer Willem Schouten in 1616. The islands remained unsettled by western Europeans until they were annexed as part of the German protectorate of German New Guinea in 1884. The area was named in honour of the Chancellor of Germany (German Reich), Chancellor Otto von Bismarck. On 1888 Ritter Island eruption and tsunami, 13 March 1888, a ...

Cypripedium
''Cypripedium'' is a genus of 58 species and nothospecies of hardy Orchidaceae, orchids; it is one of five genera that together compose the subfamily of lady's slipper orchids (Cypripedioideae). They are widespread across much of the Northern Hemisphere, including most of Europe and Africa (Algeria) (one species), Russia, China, Central Asia, Canada the United States, Mexico, and Central America. They are most commonly known as slipper orchids, lady's slipper orchids, or ladyslippers; other common names include moccasin flower, camel's foot, squirrel foot, steeple cap, Venus' shoes, and whippoorwill shoe. An abbreviation used in trade journals is "''Cyp.''" The genus name is derived from Ancient Greek (), an early reference in Greek myth to Aphrodite, and (), meaning "sandal". Most of ''Cypripedium'' grow in temperate and subtropical climates, but some species grow in the tundra in Alaska and Siberia, which is an unusually cold habitat for orchids. Other species occur well i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raceme
A raceme () or racemoid is an unbranched, indeterminate growth, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica''), radish (genus ''Raphanus''), and orchid (genus ''Phalaenopsis'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate growth, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''Pedicel (botany), pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf (: leaves) is a principal appendage of the plant stem, stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the Shoot (botany), shoot system. In most leaves, the primary Photosynthesis, photosynthetic Tissue (biology), tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, Trichome, hairiness, the number of stomata (pores that intake and output gases), the amount and ...

Shoot (botany)
In botany, a plant shoot consists of any plant stem together with its appendages like leaves, lateral buds, flowering stems, and flower buds. The new growth from seed germination that grows upward is a shoot where leaves will develop. In the spring, perennial plant shoots are the new growth that grows from the ground in herbaceous plants or the new stem or flower growth that grows on woody plants. In everyday speech, shoots are often synonymous with stems. Stems, which are an integral component of shoots, provide an axis for buds, fruits, and leaves. Young shoots are often eaten by animals because the natural fiber, fibers in the new growth have not yet completed secondary cell wall development, making the young shoots softer and easier to chew and digest. As shoots grow and age, the cells develop secondary cell walls that have a hard and tough structure. Some plants (e.g. bracken) produce toxins that make their shoots inedible or less palatable.

Pseudobulb
In botany, a pseudobulb is a storage organ found in many epiphytic and terrestrial sympodial orchids. It is derived from a thickening of the part of a stem between leaf nodes and may be composed of just one internode or several, termed ''heteroblastic'' and ''homoblastic'' respectively. All leaves and inflorescences usually arise from this structure. Pseudobulbs formed from a single internode produce the leaves and inflorescence from the top, while those that are formed from several internodes can possess leaves along its length.Hew, C.S., and J.W.H. Yong. 2004The Physiology of Tropical Orchids in Relation to the Industry.Singapore: World Scientific Publishing Co. pp. 13-15. The modified sheath leaves that appear at the base of a pseudobulb and often enfold all or part of it are usually dry and papery, though in some orchids the sheaths bear leaf blades and the leaves at the pseudobulb's apex are reduced to scales.Dressler, R.L. 1993.

Sympodial
In botany, sympodial growth is a bifurcating branching pattern where one branch develops more strongly than the other, resulting in the stronger branches forming the primary shoot and the weaker branches appearing laterally. A sympodium, also referred to as a sympode or pseudaxis, is the primary shoot, comprising the stronger branches, formed during sympodial growth. The pattern is similar to dichotomous branching; it is characterized by branching along stems or hyphae. Sympodial growth occurs when the apical meristem is terminated and growth is continued by one or more lateral meristems, which repeat the process. The apical meristem may be consumed to make an inflorescence or other determinate structure, or it may be aborted. Types If the sympodium is always formed on the same side of the branch bifurcation, e.g. always on the right side, the branching structure is called a helicoid cyme or bostryx. If the sympodium occurs alternately, e.g. on the right and then the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithophyte
Lithophytes are plants that grow in or on rocks. They can be classified as either epilithic (or epipetric) or endolithic; epilithic lithophytes grow on the surfaces of rocks, while endolithic lithophytes grow in the crevices of rocks (and are also referred to as chasmophytes). Lithophytes can also be classified as being either obligate or facultative. Obligate lithophytes grow solely on rocks, while facultative lithophytes will grow partially on a rock and on another substrate simultaneously. Nutrients Lithophytes that grow on land feed off nutrients from rain water and nearby decaying plants, including their own dead tissue. It is easier for chasmophytes to acquire nutrients because they grow in fissures in rocks where soil or organic matter has accumulated. For most lithophytes, nitrogen is only available through interactions with the atmosphere. The most readily available form of nitrogen in the atmosphere is the gaseous state of ammonia (NH3). Lithophytes consume atmospheric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epiphyte
An epiphyte is a plant or plant-like organism that grows on the surface of another plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. In some cases, a rainforest tree's epiphytes may total "several tonnes" (several long tons). They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrestrial Plant
A terrestrial plant is a plant that grows on, in or from land. Other types of plants are aquatic plant, aquatic (living in or on water), semiaquatic (living at edge or seasonally in water), epiphyte, epiphytic (living on other plants), and lithophyte, lithophytic (living in or on rocks). The distinction between aquatic and terrestrial plants is often blurred because many terrestrial plants are able to tolerate periodic submersion and many aquatic species have both wikt:submerse, submersed and wikt:emersed, emersed forms. There are relatively few obligate submersed aquatic plants (species that cannot tolerate emersion for even relatively short periods), but some examples include members of Hydrocharitaceae and Cabombaceae, ''Ceratophyllum'', and ''Aldrovanda'', and most macroalgae (e.g. ''Chara (alga), Chara'' and ''Nitella''). Most aquatic plants can, or prefer to, grow in the emersed form, and most only flower in that form. Many terrestrial plants can tolerate extended periods o ...
