Otto Wilhelm Sonder
Otto Wilhelm Sonder (18 June 1812, Bad Oldesloe – 21 November 1881) was a German botanist and pharmacist. Life A native of Holstein, Sonder studied at Kiel University, where he sat pharmaceutical examinations in 1835, before becoming the proprietor of a pharmacy in Hamburg from 1841 to 1878. In 1846 he received an honorary doctorate from the University of Königsberg and was elected a member of the German National Academy of Sciences Leopoldina for his contribution to the field of botany. Herbarium From a young age, Sonder showed considerable interest and skill in Botany. He often embarked on botanical excursions in his local area early in the morning before heading to work at the pharmacy. Throughout his life, Sonder met and conversed with many eminent botanists of the era. He amassed an extensive botanical collection that contained hundreds of thousands of specimens representing all major plant groups and spanning all parts of the globe. The collection is particularly sign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Excoecaria Madagascariensis
''Excoecaria'' is a plant genus of the family Euphorbiaceae, formally described by Linnaeus in 1759. The genus is native to the Old World Tropics (Africa, southern Asia, northern Australia, and assorted oceanic islands). Etymology Genus name, ''Excoecaria'', is from the Latin word ''excaeco'', which means "to blind" and refers to the sap of the plants that can cause temporary blindness. Toxic latex The milky latex of ''Excoecaria agallocha'', also known as ''Thillai'', milky mangrove, blind-your-eye mangrove and river poison tree, is poisonous. Mangroves of this plant surround the ancient Thillai Chidambaram Temple in Tamil Nadu. Contact with skin can cause irritation and rapid blistering; contact with eyes will result in temporary blindness. It is distributed in the Pichavaram wetlands, near Chidambaram India, in Australia from northern New South Wales, along the northern coastline around to Western Australia.The latex is extremely poisonous. Even dried and powdered leave ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allenrolfea Vaginata
''Allenrolfea'' is a genus of shrubs in the family Amaranthaceae. The genus was named for the English botanist Robert Allen Rolfe. There are three species, ranging from North America to South America. Description The species of ''Allenrolfea'' are subshrubs or shrubs with erect or decumbent growth. The stems are much branched, succulent, glabrous and appear to be articulated. The alternate leaves are sessile and stem-clasping, fleshy, glabrous, their blades reduced to small, broadly triangular scales, with entire margins and acute apex. The inflorescences are terminal spikes with spirally arranged flowers. Cymes of three or five flowers are sitting in the axils of deciduous, peltate, fleshy bracts. The flowers are bisexual. The perianth consists of 4-5 joined tepals, their lobes angled and truncate distally. There are 1-2 stamens exserting the flower and an ovary with 2(-3) stigmas. The fruit in an ovoid, compressed utricle with membranous pericarp. The erect seed is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterostachys Ritteriana
''Heterostachys'' is a genus of flowering plants in the plant family Amaranthaceae. The two species are shrubby halophytes native to South America and Central America. Description The species of ''Heterostachys'' grow as subshrubs or low shrubs. The stems are much branched, glabrous, and not jointed. The alternate leaves are fleshy, glabrous, scale-like, stem-clasping, with very short free blades (1–2 mm). The inflorescences are orbicular to cone-like, with alternate to nearly opposite scale-like bracts, and with one free flower sitting in the axil of each bract. The flowers are bisexual. The four-lobed perianth consists of four half-connate unequal tepals. There are two stamens and an ovary with two stigmas. In fruit the perianth becomes thick and spongy. The fruit wall (pericarp) is membranous. The seed is lenticular to edge-shaped with tuberculate surface. It contains a semi-annular embryo and copious perisperm (feeding tissue).

Allenrolfea Occidentalis
''Allenrolfea occidentalis'', the iodine bush, is a low-lying shrub of the Southwestern United States, California, Idaho, and northern Mexico.Shultz, L.M.: 'eFloras 2008''Allenrolfea occidentalis'' in Flora of North America Missouri Botanical Garden, St. Louis, MO & Harvard University Herbaria, Cambridge, MA. It grows in sandy, often salty, distinctly alkaline soils, such as desert washes and saline dry lakebeds. It is a common halophyte member of the alkali flat ecosystem. Description The knobby green stems are fleshy and appear jointed at the internodes between segments. Often the segments are so short they are nearly round. The leaves appear as flaky scales scattered across the surface of the stems. The genus was named for the English botanist Robert Allen Rolfe.Shultz, L.M.: 'eFloras 2008''Allenrolfea'' in Flora of North America Missouri Botanical Garden, St. Louis, MO & Harvard University Herbaria, Cambridge, MA.

International Code Of Nomenclature For Algae, Fungi, And Plants
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. The name of the ''Code'' is partly capitalized and partly not. The lower-case for "algae, fungi, and plants" indica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amaranthaceae
Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus ''Amaranthus''. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales. Description Vegetative characters Most species in the Amaranthaceae are annual or perennial herbs or subshrubs; others are shrubs; very few species are vines or trees. Some species are succulent. Many species have stems with thickened nodes. The wood of the perennial stem has a typical "anomalous" secondary growth; only in subfamily Polycnemoideae is secondary growth normal. The leaves are simple and mostly alternate, sometimes opposite. They never possess stipules. They are flat or terete, and their shape is extremely variable, with entire or toothed margins. In some species, the leaves are reduced to minute scales. In most cases, neither basal nor terminal aggrega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
