Nepenthes Andamana
''Nepenthes andamana'' is a tropical pitcher plant endemic to Phang Nga Province, Thailand, where it grows near sea level in coastal savannah and grassland. It is thought to be most closely related to '' N. suratensis''. Catalano, M. 2010. '' Nepenthes della Thailandia: Diario di viaggio''. Prague. The specific epithet ''andamana'' refers to the Andaman Sea coast of Thailand.Guerini, M. 20112010: new species of Carnivorous Plants.Associazione Italiana Piante Carnivore. Botanical history ''Nepenthes andamana'' was formally described by Marcello Catalano in his 2010 book, '' Nepenthes della Thailandia: Diario di viaggio''. The description was reviewed by Alastair Robinson, while Andreas Fleischmann provided the Latin translation. ''Catalano 013395'' was designated as the holotype. This specimen was collected by Catalano in 2009 at sea level from Takua Pa, Phang Nga Province, Thailand. It is deposited at the Chulalongkorn University Herbarium (BCU). Description ''Nepenth ...

Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant families have varieties with rosette morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern '' Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plant. Function in flowering plants Often, rosettes form in perennial plants whose upper foliage dies back with the remaining vegetation protecting the plant. Ano ...

Chulalongkorn University
Chulalongkorn University (CU, th, จุฬาลงกรณ์มหาวิทยาลัย, ), nicknamed Chula ( th, จุฬาฯ), is a public and autonomous research university in Bangkok, Thailand. The university was originally founded during King Chulalongkorn's reign as a school for training royal pages and civil servants in 1899 (B.E. 2442) at the Grand Palace of Thailand. It was later established as a national university in 1917, making it the oldest institute of higher education in Thailand. During the reign of Chulalongkorn's son, King Vajiravudh, the Royal Pages School became the Civil Service College of King Chulalongkorn. The Rockefeller Foundation was instrumental in helping the college form its academic foundation. On 26 March 1917, King Vajiravudh renamed the college "Chulalongkorn University". Chulalongkorn University is a comprehensive and research-intensive university. It is ranked as the best university in Thailand in many surveys, quality of st ...

Tendril
In botany, a tendril is a specialized stem, leaf or petiole with a threadlike shape used by climbing plants for support and attachment, as well as cellular invasion by parasitic plants such as ''Cuscuta''. There are many plants that have tendrils; including sweet peas, passionflower, grapes and Chilean glory-flower. Tendrils respond to touch and to chemical factors by curling, twining, or adhering to suitable structures or hosts. History The earliest and most comprehensive study of tendrils was Charles Darwin's monograph ''On the Movements and Habits of Climbing Plants,'' which was originally published in 1865. This work also coined the term circumnutation to describe the motion of growing stems and tendrils seeking supports. Darwin also observed the phenomenon now known as tendril perversion, in which tendrils adopt the shape of two sections of counter-twisted helices with a transition in the middle. Biology of tendrils In the garden pea, it is only the terminal leaflets ...

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 patterns of erosion or stream beds. The term derives from the Latin word ''pinna'' meaning "feather", "wing", or "fin". A similar concept is "pectination," which is a comb-like arrangement of parts (arising from one side of an axis only). Pinnation is commonly referred to in contrast to "palmation," in which the parts or structures radiate out from a common point. The terms "pinnation" and "pennation" are cognate, and although they are sometimes used distinctly, there is no consistent difference in the meaning or usage of the two words.Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Plants Botanically, pinnation is an arrangement of discr ...

Attenuate
In physics, attenuation (in some contexts, extinction) is the gradual loss of flux intensity through a medium. For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and sound at variable attenuation rates. Hearing protectors help reduce acoustic flux from flowing into the ears. This phenomenon is called acoustic attenuation and is measured in decibels (dBs). In electrical engineering and telecommunications, attenuation affects the propagation of waves and signals in electrical circuits, in optical fibers, and in air. Electrical attenuators and optical attenuators are commonly manufactured components in this field. Background In many cases, attenuation is an exponential function of the path length through the medium. In optics and in chemical spectroscopy, this is known as the Beer–Lambert law. In engineering, attenuation is usually measured in units of decibels per unit length of medium (dB/cm, dB/km, etc.) ...

Acuminate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ...

Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic 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. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...
