Dendrochilum Cobbianum
''Dendrochilum cobbianum'', or Cobb's dendrochilum, described by Heinrich Gustav Reichenbach in 1880, is an epiphytic orchid occurring in the Philippines, growing on moss-covered trees. It can sometimes occur as a lithophyte growing on rocks at altitudes above 1200 m. Description It possesses white to green-white, creamy flowers with yellow throats that emerge alongside new growth. These flowers have a diameter of 1.8 cm, rather large for this genus. They are fragrant with the scent of new mown hay. When in bloom a multitude of flowers are contained on arching inflorescences, with a length of about 50 cm. A single lanceolate leaf with prominent midrib sprouts from a conical, yellow 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 ''heter .... Cultivation This sp ...

Heinrich Gustav Reichenbach
Heinrich Gustav Reichenbach (Dresden, 3 January 1823 – Hamburg, 6 May 1889) was a botanist and the foremost Germany, German orchidologist of the 19th century. His father Ludwig Reichenbach, Heinrich Gottlieb Ludwig Reichenbach (author of ''Icones Florae Germanicae et Helveticae'') was also a well-known botanist. Biography He started his study of orchids at the age of 18 and assisted his father in the writing of ''Icones''. He became a Doctor in Botany with his work on the pollen of orchids (see ‘Selected Works’). Soon after his graduation, Reichenbach was appointed to the post of extraordinary professor of botany at the University of Leipzig, Leipzig in 1855. He then became director of the botanical gardens at the University of Hamburg, Hamburg University (1863-1889). At that time, thousands of newly discovered orchids were being sent back to Europe. He was responsible for identifying, describing, classifying. Reichenbach named and recorded many of these new discoveries. ...

Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), 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. General characteristics Inflorescences are described by many different charact ... [...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 ...

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.

Dendrochilum
__NOTOC__ ''Dendrochilum'' (commonly abbreviated ''Ddc.'' in horticulture) was a genus of epiphytic, lithophytic and a few terrestrial flowering plants in the orchid family (Orchidaceae). It is now considered to be a synonym of '' Coelogyne'' Lindl. The name of this genus was derived from Ancient Greek words ("tree"), and either ("lip")Schubert, R., & Wagner, G. (1988). ''Botanisches Wörterbuch'' (9th edition). Stuttgart: Gustav Fischer. or ("green food"), alluding to either the flowers' large lip or to their epiphytic growth. These orchids are popular among orchid collectors. Distribution and description ''Dendrochilum'' are distributed at higher elevations in the humid rainforests throughout the Malesian region, with some in the surrounding lands; thus they occur from Southeast Asia to New Guinea. However, most species are found on Borneo or the Philippines. This genus produces miniature, fragrant, star-shaped flowers that are generally produced in two rows on er ...

Endemic Orchids Of The Philippines
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...
