Astroloba Herrei
''Astroloba herrei'' is a small succulent plant of the genus ''Astroloba'', restricted to the area around the Swartberg mountains, South Africa. It is listed as a Vulnerable species on the Red List of the South African National Biodiversity Institute (SANBI). Description ''Astroloba herrei'' is a compact ''Astroloba'' species, with stems growing up to 20 cm high, that are densely covered in pointed succulent leaves. Flowers appear from June to November. With its sharp, grey-green, keeled leaves, and its puffed up, inflated flowers, the species is easily mistaken for the closely related ''Astroloba spiralis'' species. However it is genetically distinct and can always be distinguished by its flowers and its phyllotaxis. Both ''spiralis'' and ''herrei'' have puffed up, inflated flowers, but those of ''herrei'' are smooth (unlike ''spiralis'', which has a wrinkled, transversely rugose, perianth). Other less reliable ways of identifying ''herrei'' are the fine, dark, longit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Succulent Plant
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaf, leaves and Plant stem, stems. The water content of some succulent organs can get up to 90–95%, such as ''Glottiphyllum semicyllindricum'' and ''Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in Alpine climate, alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astroloba
''Astroloba'' is a genus of flowering plants in the family Asphodelaceae, subfamily Asphodeloideae,Stevens, P.F. (2001 onwards)"Asphodeloideae" ''Angiosperm Phylogeny Website'', retrieved 2016-06-10 native to the Cape Province of South Africa. Naming The name of the genus is derived from the Greek words ''astros'', star, and ''lobos'', lobe, and refers to the starlike shape of the petals, which appear at the end of the tube-like flowers. Description They are very closely related to the genus ''Haworthia'', but are distinguished by their flowers being regular and not double-tipped. The flowers are small and white, and appear clustered on slender racemes., p. 17 They bear very regular, sharp, triangular, succulent leaves along their symmetrical columnar stems. The leaves are in a number of distinctive spiral arrangements. They are slow growing, multi-stemmed, and their longer stems tend to sprawl in their rocky natural habitat.

Swartberg Mountains
The Swartberg mountains (''black mountain'' in Afrikaans) are a mountain range in the Western Cape province of South Africa. It is composed of two main mountain chains running roughly east–west along the northern edge of the semi-arid Little Karoo. To the north of the range lies the other large semi-arid area in South Africa, the Great Karoo. Most of the Swartberg Mountains are above 2000 m high, making them the tallest mountains in the Western Cape. It is also one of the longest, spanning some 230 km from south of Laingsburg in the west to between Willowmore and Uniondale in the east. Geologically, these mountains are part of the Cape Fold Belt. Much of the Swartberg is part of a UNESCO World Heritage Site. The two ranges The Swartberg consists of two officially named ranges, the Smaller and the Greater Swartberg Mountains. ''Klein Swartberge'' The Smaller Swartberg are the westernmost of the two. Ironically, this range is the higher one, including the province's high ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

1 Cream Astroloba Herrei
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astroloba Spiralis
''Astroloba spiralis'' is a small succulent plant of the Astroloba genus, endemic to the southern Karoo regions of the Western and Eastern Cape Provinces, South Africa. Description ''Astroloba spiralis'' is a compact ''Astroloba'' species, with upright, erect stems that are densely covered in pointed succulent leaves. Stems are roughly 15 cm in diameter, and reach a height of 200mm. The leaves are blue-green to grey in colour, they grow in 5 rows that sometimes form a gentle spiral. The leaves also have smooth surfaces (unlike the tubercled leaves of '' Astroloba bullulata'' and ''Astroloba corrugata''). Each leaf typically has an oblique keel near the point. The flowers appear in autumn (December to May). This species is easily confused with its close relative, the rare '' Astroloba herrei''. Both plants also have inflated, puffed up flowers (perianths). However the flowers of ''Astroloba spiralis'' are wrinkled (transversely rugose), and not smooth like those of ''herr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leaf Shape
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phyllotaxis
In botany, phyllotaxis () or phyllotaxy is the arrangement of leaf, leaves on a plant stem. Phyllotactic spirals form a distinctive class of patterns in nature. Leaf arrangement The basic leaf#Arrangement on the stem, arrangements of leaves on a stem are opposite and alternate (also known as spiral). Leaves may also be Whorl (botany), whorled if several leaves arise, or appear to arise, from the same level (at the same Node (botany), node) on a stem. With an opposite leaf arrangement, two leaves arise from the stem at the same level (at the same Node (botany), node), on opposite sides of the stem. An opposite leaf pair can be thought of as a whorl of two leaves. With an alternate (spiral) pattern, each leaf arises at a different point (node) on the stem. Distichous phyllotaxis, also called "two-ranked leaf arrangement" is a special case of either opposite or alternate leaf arrangement where the leaves on a stem are arranged in two vertical columns on opposite sides of t ...
