Medinilla Theresae
''Medinilla theresae'' is an endemic species of flowering evergreen shrub or liana in the family Melastomataceae, occurring on ultramafic soils on the dwarf forests of Mt. Redondo, Dinagat Island at 700-840 elevation, and at Mt. Hamiguitan, Philippines at growing at 900 m elevation on the edges of upper montane forest, which reaches up to the 'mossy-pygmy' forest with elevation ranges of 1160−1200 m and 1460−1600 m elevation, respectively. This terrestrial, cauliflorous shrub can grow erect at 1.5 m high. The species whorled leaves, flowers which are 4-merous, and the pendulous inflorescences likened the species to '' M. pendula''. However, it differed from the latter on distinct secondary veins on the leaves adaxial surface, the inflorescences which are cauline or axillary, and its straight anthers. Etymology The species was named in honor of Theresa Mundita Lim, a wildlife advocate, and a former director of the Biodiversity Management Bureau of the Department of Enviro ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liana
A liana is a long- stemmed, woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the canopy in search of direct sunlight. The word ''liana'' does not refer to a taxonomic grouping, but rather a habit of plant growth – much like ''tree'' or ''shrub''. It comes from standard French ''liane'', itself from an Antilles French dialect word meaning to sheave. Ecology Lianas are characteristic of tropical moist broadleaf forests (especially seasonal forests), but may be found in temperate rainforests and temperate deciduous forests. There are also temperate lianas, for example the members of the ''Clematis'' or ''Vitis'' (wild grape) genera. Lianas can form bridges amidst the forest canopy, providing arboreal animals with paths across the forest. These bridges can protect weaker trees from strong winds. Lianas compete with forest trees for sunlight, water and nutrients from the soil. Forests without lian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melastomataceae
Melastomataceae is a family of dicotyledonous flowering plants found mostly in the tropics (two-thirds of the genera are from the New World tropics) comprising c. 175 genera and c. 5115 known species. Melastomes are annual or perennial herbs, shrubs, or small trees. Description The leaves of melastomes are somewhat distinctive, being opposite, decussate, and usually with 3-7 longitudinal veins arising either from the base of the blade, plinerved (inner veins diverging above base of blade), or pinnately nerved with three or more pairs of primary veins diverging from the mid-vein at successive points above the base. Flowers are perfect, and borne either singly or in terminal or axillary, paniculate cymes. Ecology A number of melastomes are regarded as invasive species once naturalized in tropical and subtropical environments outside their normal range. Examples are Koster's curse (''Clidemia hirta''), '' Pleroma semidecandrum'' and ''Miconia calvescens'', but many other specie ...

Ultramafic
Ultramafic rocks (also referred to as ultrabasic rocks, although the terms are not wholly equivalent) are igneous and meta-igneous rocks with a very low silica content (less than 45%), generally >18% MgO, high FeO, low potassium, and are composed of usually greater than 90% mafic minerals (dark colored, high magnesium and iron content). The Earth's mantle is composed of ultramafic rocks. Ultrabasic is a more inclusive term that includes igneous rocks with low silica content that may not be extremely enriched in Fe and Mg, such as carbonatites and ultrapotassic igneous rocks. Intrusive ultramafic rocks Intrusive ultramafic rocks are often found in large, layered ultramafic intrusions where differentiated rock types often occur in layers. Such cumulate rock types do not represent the chemistry of the magma from which they crystallized. The ultramafic intrusives include the dunites, peridotites and pyroxenites. Other rare varieties include troctolite which has a greater percenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dinagat Island
Dinagat Island is an island located northeast of Mindanao in the Philippines. Until December 2006, it was part of the province of Surigao del Norte.

Merosity
Merosity (from the greek "méros," which means "having parts") refers to the number of component parts in a distinct whorl of a plant structure. The term is most commonly used in the context of a flower where it refers to the number of sepals in a whorl of the calyx, the number of petals in a whorl of the corolla, the number of stamens in a whorl of the androecium, or the number of carpels in a whorl of the gynoecium. The term may also be used to refer to the number of leaves in a leaf whorl. The adjective ''n''-merous refers to a whorl of ''n'' parts, where ''n'' is any integer greater than one. In nature, five or three parts per whorl have the highest frequency of occurrence, but four or two parts per whorl are not uncommon. Be aware that two consecutive whorls of dimerous petals are often mistaken for tetramerous petals. If all of the whorls in a given floral arrangement have the same merosity, the flower is said to be isomerous, otherwise the flower is anisomerous. For exampl ...

Department Of Environment And Natural Resources
The Department of Environment and Natural Resources ( fil, Kagawaran ng Kapaligiran at Likas na Yaman, DENR or KKLY) is the executive department of the Philippine government responsible for governing and supervising the exploration, development, utilization, and conservation of the country's natural resources. History of the DENR The Department of Environment and Natural Resources was first established on January 1, 1917, as the Department of Agriculture and Natural Resources (DANR) through the enactment of Act No. 2666 by the Philippine Commission, otherwise known as "An Act to Re-organize the Executive Department of the Government of the Philippine Islands," on November 18, 1916. In 1932, the DANR was reorganized into the Department of Agriculture and Commerce (DAC). In 1947, a reorganization act changed the DAC back to the Department of Agriculture and Natural Resources. The Natural Resources arm of the DANR was finally spun off on May 17, 1974, as the Ministry of Natural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medinilla
''Medinilla'' is a genus of about 400 species of flowering plants in the family Melastomataceae, native to tropical regions of the Old World from Africa (two species) east through Madagascar (about 70 species) and southern Asia to the western Pacific Ocean islands. The genus was named after J. de Medinilla, governor of the Mariana Islands in 1820. They are evergreen shrubs or lianas. The leaves are opposite or whorled, or alternate in some species. The flowers are white, pink, red, or orange, and are produced singly or in large panicles. Selected species There are approximately 418 species in this genus, including: *'' Medinilla acuminata'' Philippines *'' Medinilla arboricola'' China *'' Medinilla assamica'' India *'' Medinilla astronioides'' Philippines *'' Medinilla banahaensis'' Philippines *'' Medinilla beamanii'' Borneo *'' Medinilla brevipendunculata'' Philippines *'' Medinilla clemetis'' Philippines *'' Medinilla congesta'' Philippines *'' Medinilla cordata'' Phili ...

Endemic Flora Of The Philippines
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Mindanao
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
