Gasteria Baylissiana
''Gasteria baylissiana'', Suurberg gasteria, is a species of succulent flowering plant in the family Asphodelaceae, native to the Eastern Cape, South Africa. Description It is a small species, growing to tall and wide, with distichous (two rows) of strap-shaped leaves Both upper and lower surfaces of the leaves are swollen, convex, rough, leathery and densely covered in tiny, white, truncate tubercles. These tubercles are one of the easiest ways of identifying this species. In the shade, the leaves become elongated; while in sunnier conditions they remain short and compact. The plant produces offsets from the base, forming clumps, and also grows from broken leaves which root and develop shoots. In spring, a stem up to long bears a row of 15-25 bell-shaped, bright pink and green flowers, which are unusually inflated. It is often confused with '' Gasteria armstrongii'' or ''Gasteria carinata'' var. ''verrucosa'', which both have a similar squat, retuse, distichous growth fo ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...

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 t ...

Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit is a mark of quality awarded, since 1922, to garden plants (including trees, vegetables and decorative plants) by the United Kingdom, Royal Horticultural Society (RHS). Awards are made annually after plant trials intended to judge the plants' performance under UK growing conditions. Trials may last for one or more years, depending on the type of plant being analyzed, and may be performed at Royal Horticulture Society Garden in Wisley and other gardens or after observation of plants in specialist collections. Trial reports are made available as booklets and on the website. Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars. Similar awards The award should not be ...

Royal Horticultural Society
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Sue Biggs CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discoveries, to enc ...

Addo Elephant National Park
Addo Elephant National Park is a diverse wildlife conservation park situated close to Gqeberha in South Africa and is one of the country's 20 national parks. It currently ranks third in size after Kruger National Park and the Kgalagadi Transfrontier Park. History The original section of the park was founded in 1931, in part due to the efforts of Sydney Skaife, in order to provide a sanctuary for the eleven remaining elephants in the area. The park has proved to be very successful and currently houses more than 600 elephants and a large number of other mammals. Expansion The original park has subsequently been expanded to include the Woody Cape Nature Reserve that extends from the Sundays River mouth towards Alexandria and a marine reserve, which includes St. Croix Island and Bird Island, both breeding habitat for gannets and penguins, not to mention a large variety of other marine life. Bird Island is home to the world's largest breeding colony of gannets - about 120,000 ...

Gasteria Bicolor
''Gasteria bicolor'' (previously named ''Gasteria obliqua'' or ''Gasteria maculata'') is a species of succulent flowering plant in the family Asphodelaceae, native to the Eastern Cape, South Africa. Description This is a very variable species of ''Gasteria'', common in cultivation. It grows multiple proliferous stems, all covered in untidy masses of the shiny, mottled, colourful, succulent leaves. It usually forms rosettes, but can sometimes be distichous, especially in cultivation. The leaves can also occasionally develop a keel. Each leaf has a sharp point on the tip. The flowers generally appear on a long stem of about , that carries tubular bell-shaped pink to orange flowers.

Gasteria Armstrongii
''Gasteria'' is a genus of succulent plants, native to South Africa (and the far south-west corner of Namibia). Naming The genus is named for its stomach-shaped flowers (''"gaster"'' is Latin for "stomach") that result from the swollen base on the corolla. Common names include ''ox-tongue'', ''cow-tongue'', ''lawyer's tongue'' and, occasionally, ''mother-in-law's tongue''. Description Gasterias are recognisable from their thick, hard, succulent "tongue-shaped" leaves. These are either in two opposite ranks (distichous), or in various distinctive spiral arrangements. Their inflorescence is also unique, with their curved, stomach-shaped flowers, which hang from inclined racemes. Distribution The species of this genus are mostly native to the Eastern Cape Province, South Africa, where the bulk of the species occur – especially in the small area between Makhanda and Uniondale which enjoys rainfall throughout the year. However distribution of several species extends widely a ...

Tubercle
In anatomy, a tubercle (literally 'small tuber', Latin for 'lump') is any round nodule, small eminence, or warty outgrowth found on external or internal organs of a plant or an animal. In plants A tubercle is generally a wart-like projection, but it has slightly different meaning depending on which family of plants or animals it is used to refer to. In the case of certain orchids and cacti, it denotes a round nodule, small eminence, or warty outgrowth found on the lip. They are also known as podaria (singular ''podarium''). When referring to some members of the pea family, it is used to refer to the wart-like excrescences that are found on the roots. In fungi In mycology, a tubercle is used to refer to a mass of hyphae from which a mushroom is made. In animals When it is used in relation to certain dorid nudibranchs such as '' Peltodoris nobilis'', it means the nodules on the dorsum of the animal. The tubercles in nudibranchs can present themselves in different ways: e ...

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, ...

Distichous
In botany, phyllotaxis () or phyllotaxy is the arrangement of leaves on a plant stem. Phyllotactic spirals form a distinctive class of patterns in nature. Leaf arrangement The basic arrangements of leaves on a stem are opposite and alternate (also known as spiral). Leaves may also be whorled if several leaves arise, or appear to arise, from the same level (at the same node) on a stem. With an opposite leaf arrangement, two leaves arise from the stem at the same level (at the same 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 the stem. Examples include various bulbous plants such as ''Boophone''. It also ...
