Hemiepiphytic
A hemiepiphyte is a plant that spends part of its life cycle as an epiphyte. The seeds of primary hemiepiphytes germinate in the canopy and initially live epiphytically. They send roots downward, and these roots eventually make contact with the ground. Secondary hemiepiphytes are root-climbers that begin as rooted vines growing upward from the forest floor, but later break their connection to the ground. When this happens, they may send down long roots to the ground.Mayo et al. "Araceae" in Kubitzki (1998b ''The families and genera of vascular plants''): "The root climbers and hemiepiphytes normally grow in humid forests, often very high in the canopy. When losing connection with the forest floor, they may send down long roots to the ground; such plants may be referred to as secondary hemiepiphytes. Hemiepiphytes and root climbers cling tightly to the bark of the host with negatively phototropic roots. Skototropism, an orientation movement towards a well-defined dark area, has ...

Elaeocarpus Holopetalus Hemiepiphyte Devils Creek Tantawangalo
''Elaeocarpus'' is a genus of nearly five hundred species of flowering plants in the family Elaeocarpaceae native to the Western Indian Ocean, Tropical and Subtropical Asia, and the Pacific. Plants in the genus ''Elaeocarpus'' are trees or shrubs with simple leaves, flowers with four or five petals usually, and usually blue fruit. Description Plants in the genus ''Elaeocarpus'' are mostly evergreen trees or shrubs, a few are epiphytes or lianes, and some are briefly deciduous. The leaves are arranged alternately, simple (strictly compound with only one leaflet) with a swelling where the petiole meets the lamina, often have toothed edges, usually have prominent veins and often turn red before falling. The flowers are usually arranged in a raceme, usually bisexual, have four or five sepals and petals and many stamens. The petals usually have finely-divided, linear lobes. The fruit is an oval to spherical drupe that is usually blue, sometimes black, with a sculptured endocarp. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Eucryphia Moorei & Dicksonia Monga
''Eucryphia'' is a small genus of trees and large shrubs native to the south temperate regions of South America and coastal eastern Australia, mainly Tasmania. Sometimes placed in a family of their own, the Eucryphiaceae, they are placed by more recent classifications in the Cunoniaceae. There are seven species, two in South America and five in Australia, and several named hybrids. Description They are mostly evergreen though one species (''E. glutinosa'') is usually deciduous. The leaves are opposite, and either simple or pinnate with 3-13 leaflets. The flowers are produced in late summer or autumn, are showy and sweetly scented, 3–6 cm diameter, with four creamy-white petals, and numerous stamens and styles. The fruit is a woody capsule 1-1.5 cm long containing several seeds, and maturing in 12–15 months. Etymology The generic name ''Eucryphia'' is composed of two parts, namely ''eu-'' and ''-cryphia''. The Greek ευ-κρυφαιος means well-covered and r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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] [Amazon] |
Forest Floor
The forest floor, also called detritus or wikt:duff#Noun 2, duff, is the part of a forest ecosystem that mediates between the living, aboveground portion of the forest and the mineral soil, principally composed of dead and decaying plant matter such as rotting wood and shed leaf, leaves. In some countries, like Canada, forest floor refers to L, F and H organic horizons. It hosts a wide variety of decomposers and predators, including invertebrates, fungi, algae, bacteria, and archaea. The forest floor serves as a bridge between the above ground living vegetation and the soil, and thus is a crucial component in nutrient transfer through the biogeochemical cycle. Leaf litter and other plant litter transmits nutrients from plants to the soil. The plant litter of the forest floor (or L horizon) prevents erosion, conserves moisture, and provides nutrients to the entire ecosystem. The F horizon consists of plant material in which decomposition is apparent, but the origins of plant res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Monstera Tenuis
''Monstera tenuis'' (common name Chirravaca) is a species of flowering plant in the family ''Araceae''. It is native to Central America, from Nicaragua to Panama. It grows in wet tropical habitats below . Like many others in its genus, like '' Monstera dubia'', the plant starts life on the forest floor and then as a root climber climbs tree trunks to a height of 30 metres in a shingling fashion with leaves tightly appressed to the surface of the trunk. When it reaches a sufficient height, the leaf morphology dramatically changes to pinnate Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, and ... in nature, and it develops very long aerial roots.Madison, Contributions, loc.cit. The name of the species, which means "thin" in Latin, refers to the juvenile leaves. References tenu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Girdling
Girdling, also called ring-barking, is the circumferential removal or injury of the bark (consisting of cork cambium or "phellogen", phloem, cambium and sometimes also the xylem) of a branch or trunk of a woody plant. Girdling prevents the tree from sending nutrients from its foliage to its roots, resulting in the death of the tree over time, and it can also prevent flow of nutrients in the other direction depending on how much of the xylem is removed. A branch completely girdled will fail; and, when the main trunk of a tree is girdled, the entire tree will die if it cannot regrow from above to bridge the wound. Human practices of girdling include forestry, horticulture, and vandalism. Foresters use the practice of girdling to thin forests. Extensive cankers caused by certain fungi, bacteria or viruses can girdle a trunk or limb. Animals such as rodents will girdle trees by feeding on outer bark, often during winter under snow. Girdling can also be caused by herbivorou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Ecology Terminology
Ecology () is the natural science of the relationships among living organisms and their environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere levels. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and is the study of abundance, biomass, and distribution of organisms in the context of the environment. It encompasses life processes, interactions, and adaptations; movement of materials and energy through living communities; successional development of ecosystems; cooperation, competition, and predation within and between species; and patterns of biodiversity and its effect on ecosystem processes. Ecology has practical applications in fields such as conservation biology, wetland management, natural resource management, and human ecology. The word ''ecology'' () was coined in 1866 by the German scientist Ern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Plant Morphology
Phytomorphology is the study of the physical form and external structure of plants.Raven, P. H., R. F. Evert, & S. E. Eichhorn. ''Biology of Plants'', 7th ed., page 9. (New York: W. H. Freeman, 2005). . This is usually considered distinct from plant anatomy, which is the study of the internal structure of plants, especially at the microscopic level. Plant morphology is useful in the visual identification of plants. Recent studies in molecular biology started to investigate the molecular processes involved in determining the conservation and diversification of plant morphologies. In these studies transcriptome conservation patterns were found to mark crucial ontogenetic transitions during the plant life cycle which may result in evolutionary constraints limiting diversification. Scope Plant morphology "represents a study of the development, form, and structure of plants, and, by implication, an attempt to interpret these on the basis of similarity of plan and origin".
