Rhamphospermum Arvense
''Rhamphospermum arvense'', (syns. ''Brassica arvensis'' and ''Sinapis arvensis'') the charlock mustard, field mustard, wild mustard, or just charlock, is an annual or winter annual plant in the family Brassicaceae. It is found in the fields of North Africa, Asia, Europe, and some other areas where it has been transported and naturalized. '' Pieris rapae'', the small white butterfly, and '' Pieris napi'', the green veined white butterfly, are significant consumers of charlock during their larval stages. Description ''Rhamphospermum arvense'' reaches on average in height, but under optimal conditions can exceed one metre. The stems are erect, branched and striated, with coarse spreading hairs especially near the base. The leaves are petiolate (stalked) with a length of . The basal leaves are oblong, oval, lanceolate, lyrate, pinnatifid to dentate, long, wide. The cauline leaves are much reduced and are short petiolate to sessile but not auriculate-clasping. It blooms fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhamphospermum Nigrum
''Rhamphospermum nigrum'' (syns. ''Brassica nigra'' and ''Sinapis nigra''), black mustard, is an annual plant cultivated for its dark-brown-to-black seeds, which are commonly used as a spice. It is native to cooler regions of North Africa, temperate regions of Europe, and parts of Asia. Description It is an upright plant, with large stalked leaves. They are covered with hairs or bristles at the base, but on the stem smoother. It can reach up to tall in moist fertile soil. It blooms in summer, from May (in the UK) onwards. The flowers have four yellow petals, which are twice as long as the sepals. Each stem has around four flowers at the top, forming a ring around the stem. Later, the plant forms long seed pods, that contain rounded seeds. Taxonomy It was formally described by Karl Koch in "Deutschl. Fl." (or Deutschlands Flora) ed.3 on page 713 in 1833. This was based on a description by the Swedish botanist Carl Linnaeus. The Latin-specific epithet ''nigrum'' is derived f ...

He also used the pseudonym Stary Detiuk, meaning "old Detiuk". Early life and education Andrzejowski was born the son of a bank clerk and property manager in the village of in the present-day Rivne Oblast in Ukraine. He grew up in various places in western Ukraine and studied in Vilnius after his father's death in 1801. Andrzejowski was a student of the botanists Franz Scheidt and Wilibald Swibert Joseph Gottlieb von Besser in Kremenets. Career in botany Andrzejowski was a teacher at the lyceum in Kremenets. After his Polish-language lyceum was dissolved in 1832, he was an assistant to Wilibald Swibert Joseph Gottlieb von Besser and lecturer at Kiev University beginning in 1832.

Wilibald Swibert Joseph Gottlieb Von Besser
Wilibald Swibert Joseph Gottlieb von Besser (7 July 1784 – 11 October 1842), known in Russia as Vilibald Gotlibovich Besser (russian: Вилибальд Готлибович Бессер) was an Austrian-born botanist active in the Russian Empire, who worked most of his life within the territory of western Ukraine. Born in Innsbruck, he lost both of his parents when he was 13, after which he was raised by his godfather, , who was a professor of botany at the University of Lemberg. Besser received his initial education at Lemberg, then entered university there to study medicine while also practising botany under the guidance of Schivereck, starting a large collection of botanical specimens. Upon the closure of the University of Lemberg, von Besser accompanied Schivereck to his new teaching position in Krakow, where the latter passed away in 1806, leaving his godson with his herbarium. Von Besser graduated as a doctor from the University of Krakow in 1807, and continued to pursue hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Brassicaceae
Brassicaceae () or (the older) Cruciferae () is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are ''Draba'' (440 species), ''Erysimum'' (261 species), ''Lepidium'' (234 species), ''Cardamine'' (233 species), and ''Alyssum'' (207 species). The family contains the cruciferous vegetables, including species such as ''Brassica oleracea'' (cultivated as cabbage, kale, cauliflower, broccoli and collards), ...
