Adromischus Cristatus
''Adromischus cristatus'' is a species of succulents from the family Crassulaceae, endemic to the eastern cape of South Africa. It is a perennial with short erect branches 20–50 mm long covered with fine aerial roots. Leaves are green to gray-green, with undulating margin, and generally measuring 20–40 × 5–13 mm. During the springtime, it sends up long narrow stalks for its flowers, which are tubular in shape and white in color with hints of red. Common names for this plant include "Key Lime Pie" and "Crinkle Leaf Plant." Horticulture This plant grows best given bright light and good airflow. Plant in cacti/succulent potting soil for ample drainage and provide water when the soil is dry. Water less frequently during the winter. While hardy down to freezing temperatures (32 °F or 0 °C), avoid exposure to frost. ''Adromischus cristatus'' is hardy to USDA hardiness zone A hardiness zone is a geographic area defined as having a certain average ann ...

Adrian Hardy Haworth
Adrian is a form of the Latin given name Adrianus or Hadrianus. Its ultimate origin is most likely via the former river Adria from the Venetic and Illyrian word ''adur'', meaning "sea" or "water". The Adria was until the 8th century BC the main channel of the Po River into the Adriatic Sea but ceased to exist before the 1st century BC. Hecataeus of Miletus (c.550 – c.476 BC) asserted that both the Etruscan harbor city of Adria and the Adriatic Sea had been named after it. Emperor Hadrian's family was named after the city or region of Adria/Hadria, now Atri, in Picenum, which most likely started as an Etruscan or Greek colony of the older harbor city of the same name. Several saints and six popes have borne this name, including the only English pope, Adrian IV, and the only Dutch pope, Adrian VI. As an English name, it has been in use since the Middle Ages, although it did not become common until modern times. Religion *Pope Adrian I (c. 700–795) *Pope Adrian II (792–872 ...

Charles Antoine Lemaire
Charles Antoine Lemaire (1 November 1800, in Paris – 22 June 1871, in Paris), was a French botanist and botanical author, noted for his publications on Cactaceae. Education Born the son of Antoine Charles Lemaire and Marie Jeanne Davio, he had an excellent early education, and acquired the reputation of being an outstanding scholar. He studied at the University of Paris and was appointed as Professor of Classical Literature there. At some stage his botanical interest was sparked and developed by his association with M. Neumann, horticulturist at the Muséum national d'histoire naturelle, Museum of Natural History. Career He worked for some time as an assistant to M. Mathieu, at a nursery in Paris, building up a collection of Cactaceae, a group to which he would devote almost all of his life. In 1835, M. Cousin, a Parisian publisher, started a gardening journal and requested that he be its editor. For a number of years, he remained editor of ''Jardin Fleuriste'' and ''L'Horticu ...

Erich Werdermann
Erich Werdermann (2 March 1892 – 20 April 1959) was a German botanist. Born in Berlin, Erich Werdermann was the son of the landowner Carl Werdermann. He first studied in Jena, but then switched to Friedrich Wilhelm University (now called Humboldt University of Berlin) in Berlin. In 1914 shortly before his graduation, Werdermann was enlisted in the army and in 1915 promoted to the rank of officer. After recovering from serious wounds suffered in 1918, he was able to continue his studies. The following year Werdermann graduated as a plant physiologist at Gottlieb Haberlandt. From 1919 to 1920 he worked at the Imperial Biological Institute in Berlin, where Peter Claussen (1877–1959) sparked his interest in fungi. From 1920 to 1921, Mann was a research assistant at the Imperial Health Office with Ernst Friedrich Gilg, who introduced him to the Botanical Museum Berlin-Dahlem. In 1921, he succeeded Rudolf Schlechter as the curator of mushrooms in the herbarium of the museum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Succulents
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 leaves and 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 ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them equipped to s ...

Crassulaceae
The Crassulaceae (from Latin ''crassus'', thick), also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus ''Sedum'', and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic. Crassulaceae are mainly pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...
