Strumaria Phonolithica
''Strumaria phonolithica'' is an Amaryllidaceous plant species (tribe Amaryllideae) endemic to Namibia. Its narrow funnel-shaped flowers are, jointly with those of ''Strumaria barbarae'', the largest in the genus. It grows in subtropical shrubland, tropical dry shrubland and rocky areas in the Aurus and Klinghardt Mountains of the Tsau ǁKhaeb Sperrgebiet National Park in southwestern Namibia, where it is usually to be found growing in phonolite gravels (- whence the specific name phonolithica) South African National Biodiversity Institute, plantzafrica.com https://pza.sanbi.org/strumaria-phonolithica Retrieved at 8.34 on Tuesday 14/11/23.Dinter, Moritz Kurt. 1923.

Phonolite
Phonolite is an uncommon extrusive rock, of intermediate chemical composition between felsic and mafic, with texture ranging from aphanitic (fine-grained) to porphyritic (mixed fine- and coarse-grained). Phonolite is a variation of the igneous rock trachyte that contains nepheline or leucite rather than quartz. Its intrusive equivalent is nepheline syenite. Phonolite is typically fine grained and compact. The name ''phonolite'' comes from the Ancient Greek meaning "sounding stone" due to the metallic sound it produces if an unfractured plate is hit; hence, the English name ''clinkstone'' is given as a synonym. Formation Unusually, phonolite forms from magma with a relatively low silica content, generated by low degrees of partial melting (less than 10%) of highly aluminous rocks of the lower crust such as tonalite, monzonite and metamorphic rocks. Melting of such rocks to a very low degree promotes the liberation of aluminium, potassium, sodium and calcium by meltin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern Plants
Comparison is a feature in the morphology or syntax of some languages whereby adjectives and adverbs are inflected to indicate the relative degree of the property they define exhibited by the word or phrase they modify or describe. In languages that have it, the comparative construction expresses quality, quantity, or degree relative to ''some'' other comparator(s). The superlative construction expresses the greatest quality, quantity, or degree—i.e. relative to ''all'' other comparators. The associated grammatical category is degree of comparison. The usual degrees of comparison are the ''positive'', which simply denotes a property (as with the English words ''big'' and ''fully''); the ''comparative'', which indicates ''greater'' degree (as ''bigger'' and ''more fully''); and the ''superlative'', which indicates ''greatest'' degree (as ''biggest'' and ''most fully''). Some languages have forms indicating a very large degree of a particular quality (called ''elative'' in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1923
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the abili ...

Strumaria
''Strumaria'' is a genus of African plants in Amaryllis family, subfamily Amaryllidoideae. The genus is known in nature only from South Africa, Lesotho and Namibia. Almost all species flower in the autumn and are cultivated as ornamental bulbous plants. Description Species of ''Strumaria'' are deciduous bulbous plants. Their bulbs are generally small, around in diameter with a fibrous bulb tunic. Usually two leaves are produced, although there may be up to six. The flowers generally appear in the autumn with the arrival of the rains; the leaves may appear before, with, or after the flowers. The inflorescence is tall, with an umbel of two to 30 flowers, generally carried on long pedicels. Most species have white flowers, although they may also be pink or yellow. The six stamens are joined to the style, at least at the base. ''Strumaria'' is distinguished from other genera in the family Amaryllidaceae by the presence of a thickening at the base of the style, except in '' Strumar ...

Flora Of Namibia
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. 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 Thurma ...

Sexual Reproduction
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete ( haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes ( diploid). This is typical in animals, though the number of chromosome sets and how that number changes in sexual reproduction varies, especially among plants, fungi, and other eukaryotes. Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants. Sexual reproduction also occurs in some unicellular eukaryotes. Sexual reproduction does not occur in prokaryotes, unicellular organisms without cell nuclei, such bacteria and archaea. However, some process in bacteria may be considered analogous to sexual reproduction in that they incorporate new genetic information, including bacterial conjugation, transf ...

Offset (botany)
In botany and horticulture, an offset (also called a pup) is a small, virtually complete daughter plant that has been naturally and asexually produced on the mother plant. They are clones, meaning that they are genetically identical to the mother plant. They divide mitotically. In the plant nursery business and gardens, they are detached and grown in order to produce new plants. This is a cheap and simple process for those plants that readily produce offsets as it does not usually require specialist materials and equipment. An offset or pup may also be used as a broad term to refer to any short shoot originating from the ground at the base of another shoot. Offsets form when meristem regions of plants, such as axillary buds or homologous structures, differentiate into a new plant with the ability to become self-sustaining. This is particularly common in species that develop underground storage organs, such as bulbs, corms and tubers. Tulips and lilies are examples of plants ...

Vegetative Reproduction
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules. Many plants naturally reproduce this way, but it can also be induced artificially. Horticulturists have developed asexual propagation techniques that use vegetative propagules to replicate plants. Success rates and difficulty of propagation vary greatly. Monocotyledons typically lack a vascular cambium, making them more challenging to propagate. Background Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts. Wh ...

Tsau ǁKhaeb Sperrgebiet National Park
The , formerly known as Sperrgebiet (German language, German, meaning "Prohibited Area"; also known as Diamond Area 1), is a diamond mining area in southwestern Namibia, in the Namib Desert. It spans the Atlantic Ocean-facing coast from Oranjemund on the border with South Africa, to around north of Lüderitz, a distance of north. It extends to around inland, and its total area of , makes up three percent of Namibia's land mass. However, mining only takes place in five percent of the Sperrgebiet, with most of the area acting as a buffer zone. Members of the public are banned from entering most of the area, despite the creation of a national park there in 2004. History After the first diamond was found in April 1908 by August Stauch near Grasplatz station, a diamond rush was triggered in German South West Africa. In September 1908, the German government created the Sperrgebiet in its colony in order to make its South West African enterprise profitable, giving sole right ...

Moritz Kurt Dinter
Moritz Kurt Dinter (10 June 1868 – 16 December 1945) was a German botanist and explorer in South West Africa. Education and career Dinter was born in Bautzen, where he attended the Realschule. Having completed his military service and joined the Botanic Gardens at Dresden and Strasbourg to further his botanical and horticultural interests. He was appointed assistant to Prof. Carl Georg Oscar Drude, the plant geographer, in Dresden. As a result of his keen interest in exotic succulents, he was selected by Sir Thomas Hanbury to manage his acclimatisation garden, the Giardini Botanici Hanbury at La Mortola, near Ventimiglia on the Italian Riviera. This garden had a large collection of South African bulbs and succulents. He also spent about six months at Kew, returned to La Mortola and decided on a trip to South West Africa. He landed at Swakopmund in June 1897, having sailed on the "Melitta Bohlem". Dinter started his collection in the countryside around Swakopmun ...

Klinghardt Mountains
The Klinghardt Mountains are a Namibian mountain range in the Diamond Restricted Area, also called Sperrgebiet. The Klinghardt Mountains are located approximately 90 km south-southeast of Lüderitz and extend over an area of about 350 km2. East of the Klinghardt Mountains is the mountain Höchster. Several places of the mountain range are covered with sand which is blown over by sandstorms. The average yearly rainfall in this area of the Namib desert amounts to just a few millimeters.Fog desert A fog desert is a type of desert where fog drip supplies the majority of moisture needed by animal and plant life. Examples of fog deserts include the Atacama Desert of coastal Chile and Peru, the Baja California Desert of Mexico, the Namib D ...
