Dransfieldia
''Dransfieldia'' is a monotypic genus of flowering plant in the palm family from western New Guinea where the lone species ''Dransfieldia micrantha'' grows in dense rain forest. Discovered in 1872, 134 years passed before DNA testing revealed its proper placement. With no close relatives, it is a delicate, pinnate-leaved palm named after John Dransfield, former palm expert at the Kew Royal Botanic Gardens. Description The thin trunk is solitary, gray to maroon in color, with distinct, widely spaced leaf scar rings. The leaf sheaths are extended, forming a distinct green crownshaft; the small rachis bears widely spaced, acute leaflets, slightly offset and taper to a point. The inflorescence is borne beneath the crownshaft, protected by a caducous prohyll, once-branched, producing one-seeded fruit with apical remains.Norup, Maria Vibe Dransfield, John Chase, Mark W.

John Dransfield
John Dransfield (born 1945) is former head of palm research at the Royal Botanic Gardens, Kew, United Kingdom. Dransfield has written or contributed to several books on palms, notably both the first and second editions of '' Genera Palmarum''. The first edition was the standard reference for palm evolution and classification and the second edition, expanding on the original, is expected to achieve that same benchmark. He studied at the University of Cambridge, B.A.(1967) biology, M.A. (1970) botany and Ph.D. biology (1970) before working at Kew Gardens. Dransfield was awarded the inaugural David Fairchild Medal for Plant Exploration in 1999, recognising him as the "world authority on the systematics of the palm family (''Arecaceae'')". In 2004, he was awarded the Linnean Medal, an annual award given by the Linnean Society of London. In 2023 Dr. Dransfield was the recipient of the Dent Smith Memorial Award, the highest accolade from the International Palm Society. The genus ...

Monotypic Arecaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Humidity
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation (meteorology), precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 8 g of water per cubic metre of air at , and 28 g of water per cubic metre of air at Three primary measurements of humidity are widely employed: abso ...

Undergrowth
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy, so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines, and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upward to fill the gap. These trees tend to have straight trunks ...

Heterospathe
''Heterospathe'' is a monoecious genus of flowering plant in the palm family found in Oceania, where it is called sagisi palm. With 39 species, ''Heterospathe'' is named from a Greek combination of "various" and "spathe", which describes the two distinct bract types. Description They exhibit considerable variation in morphology and habit; the slender trunks may be solitary or sparsely to densely clustering, some are miniatures and perpetual undergrowth subjects while others contribute to the canopy top. The trunks are ringed by leaf scars and end in a poorly defined or absent crownshaft. The leaves are usually pinnate, rarely bifid, from small to large, and frequently red colored when new. The inflorescence is interfoliar but will hang pendent nearing antithesis. It may be branched from one to four orders with short white to yellow branches of spirally arranged, male and female flowers. Ellipsoidal to spherical, the fruit ripen to various shades of orange and red and contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
