Acanthus (genus)
''Acanthus'' is a genus of about 30 species of flowering plants in the family Acanthaceae, native to tropical and warm temperate regions, with the highest species diversity in the Mediterranean Basin and Asia. This flowering plant is nectar-producing and depends on Butterfly, butterflies, such as ''Anartia fatima'', and other nectar-feeding organisms to distribute its pollen. Common names include Acanthus and bear's breeches. The generic name derives from the Greek term (''akanthos'') for ''Acanthus mollis'', a plant that was commonly imitated in Corinthian capitals. The genus comprises Herbaceous plant, herbaceous perennial plants, rarely subshrubs, with spiny leaves and flower raceme, spikes bearing white or purplish flowers. Size varies from in height.

Acanthus Montanus
''Acanthus montanus'', also known as bear's breech or mountain thistle and in Igbo; ''ogwu_ahga'' (in Agbani, Enugu State Nigeria) is a species of flowering plant in the genus ''Acanthus (plant), Acanthus''. It is native to tropical Africa, growing in wet and shady places like stream borders in Sierra Leone in West Africa and from Benin to Chad, Zambia, and Angola in central Africa. It is a thinly branched Perennial plant, perennial with basal clusters of oblong to lance-shaped glossy, dark green leaves reaching up to long. The leaves have silver marks, wavy margins and thorns. It reaches up to tall and about wide. Spikes of pale pink flowers appear summer to fall. In cultivation it prefers shady situations and occasional deep watering, but tolerates sunny, dry situations too. Its aggressive roots make this plant well suited to slopes.

Raceme
A raceme () or racemoid is an unbranched, indeterminate growth, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica''), radish (genus ''Raphanus''), and orchid (genus ''Phalaenopsis'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate growth, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''Pedicel (botany), pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthus Eminens
''Acanthus eminens'' is a species of flowering plant in the genus '' Acanthus''. It is primarily found in the tropical regions of Eastern Africa, particularly in Ethiopia, South Sudan, Uganda and Kenya. Description It is a perennial In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also ... shrub that typically grows up to tall. It has pinnatifid, dark green leaves with deeply lobed margins. The flowers are produced in tall, dense spikes, being purple or violet, or blue in colour. It suffers from fragmentation, pollinator limitation, and inbreeding.

Acanthus Ebracteatus
''Acanthus ebracteatus'' is a species of shrubby herb that grows in the undergrowth of mangroves of south-east Asia. Common names include sea holly and holly mangrove. Description It grows as an erect, spreading or scrambling shrubby herb, up to 1.5 metres tall, usually with a great many stems. Its leaves are dark green, stiff, with sharp spines at the end of each deep lobe: very much like those of holly (''Ilex''). Flowers are blue, purple or white, and occur in spikes terminal on the branches. The fruit is a square-shaped capsule, which explodes when ripe, projecting the seeds up to two metres from the plant. Seeds are off-white and flat. Taxonomy This species was first described by Martin Vahl in his 1791 ''Symbolae Botanicae''. In 1806 Christiaan Persoon transferred it into '' Dilivaria'', but this was not accepted. Two subspecies are recognised, the autonym ''A. ebracteatus'' subsp. ''ebracteatus'', and ''A. ebracteatus'' subsp. ''ebarbatus'', described in 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Ludwig Willdenow
Carl Ludwig Willdenow (22 August 1765 – 10 July 1812) was a German botanist, pharmacist, and plant Taxonomy (biology), taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt, one of the earliest and best known phytogeographers. He also influenced Christian Konrad Sprengel, who pioneered the study of plant pollination and floral biology. Biography Willdenow was born in Berlin and studied medicine and botany at the University of Halle. After studying pharmaceutics at Wieglieb College, Langensalza and in medicine at Halle, he returned to Berlin to work at his father's pharmacy located in the Unter den Linden. His early interest in botany was kindled by his uncle Johann Gottlieb Gleditsch, J. G. Gleditsch and he started a herbarium collection in his teenage years. In 1794, he became a member of the Berlin Academy of Sciences. He was a director of the Botanica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
