Spathiostemon
''Spathiostemon'' is a genus of trees in the Euphorbiaceae family. It is native to the Bismarck Archipelago, New Guinea, Wallacea and Southeast Asia. The trees grow between 10 and 20m tall, often in secondary forest. The wood is sometimes used. Description The two species occur as trees or shrubs up to 20m tall. They are monoecious, that is individual trees have both female and male flowers though the sexes flower at different times. Leaves are spirally arranged and simple in form, papery. Flowers do not have petals. Woody thin-walled capsules are slightly lobed, glabrous (hairless) and either smooth or spiny. There are usually 2-3 seeds per fruit, obovoid (rounded at both ends), and slightly triangular in cross/transverse section. The genus is distinguished from other Malesian Euphorbiaceae by the following traits: if present the latex is not obvious; hairs are present; pistillate (female) flowers have apically split stigmas; the male (staminate) flowers have stamens that split i ...

Clonostylis Forbesii
''Clonostylis'' is a monotypic genus of flowering plant in the family Euphorbiaceae. The sole species is ''Clonostylis forbesii'' is a flowering tree found in Sumatra. It has small glabrous leaves with an elliptic shape, arranged spirally. Taxonomy It was previously thought that ''Clonostylis'' S.Moore was a synonym of ''Spathiostemon'' Blume, but now ''Clonostylis'' is provisionally treated as a monotypic genus. Since only one specimen has been found, according to the Nationaal Herbarium Nederland, and it did not exhibit fruit or staminate flowers, a more definite classification is not yet possible. (The species is unisexual, and the specimen in question had only pistillate Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' ... flowers.) References * Welzen, P.C. van. 1998. ...

Carl Ludwig Blume
Charles Ludwig de Blume or Karl Ludwig von Blume (9 June 1796, Braunschweig – 3 February 1862, Leiden) was a German-Dutch botanist. He was born at Braunschweig in Germany, but studied at Leiden University and spent his professional life working in the Dutch East Indies and in the Netherlands, where he was Director of the Rijksherbarium (state herbarium) at Leiden. His name is sometimes given in the Dutch language form Karel Lodewijk Blume, but the original German spelling is the one most widely used in botanical texts: even then there is confusion, as he is sometimes referred to as K.L. Blume (from Karl). He carried out extensive studies of the flora of southern Asia, particularly in Java, then a colony of the Netherlands. From 1823 to 1826 Blume was Deputy Director of Agriculture at the botanic garden in Bogor (Buitenzorg) in Java. In 1827 he became correspondent of the Royal Institute of the Netherlands. In 1855, he was elected a foreign member of the Royal Swedish Ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
João De Loureiro
João de Loureiro (1717, Lisbon – 18 October 1791) was a Portuguese Jesuit missionary and botanist. Biography After receiving admission to the Jesuit Order, João de Loureiro served as a missionary in Goa, capital of Portuguese India (3 years) and Macau (4 years). In 1742 he traveled to Cochinchina, remaining there for 35 years. Here he worked as a mathematician and naturalist for the king of Cochinchina, acquiring knowledge on the properties and uses of native medicinal plants. In 1777, he journeyed to Canton, in Bengal, returning to Lisbon four years later. During this period, the Captain Thomas Riddel gave Loureiro the books ''Systema Naturae'', ''Genera Plantarum'' and ''Philosophia Botanica'' by Carl Linnaeus, which greatly influenced the Portuguese botanist. The first 40 years he stayed in Vietnam, João de Loureiro was inventorying indigenous herbal remedies. His local garden contained 1,000 unique herbal species, making him one of the greatest botanist collectors o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Justus Carl Hasskarl
Justus Carl Hasskarl (6 December 1811 – 5 January 1894) was a German explorer and botanist specializing in Pteridophytes, Bryophytes and Spermatophytes. He was co-founder of the Society of Natural Curiosities of India, in Bavaria and spent his time researching flora of Indonesia for years. Biography Justus Carl Hasskarl was born in Kassel in the Kingdom of Westphalia. In his earlier life he studied at a plant nursery in Poppelsdorf in 1827. And later in 1834 he studied Natural History while at the same time, prepared himself for an expedition to the tropics. In 1836, he traveled to Java and tried to make a living through his knowledge in Physics and Medicine, with little success. Subsequently, he sent a request to the Governor general to work in 's Lands Plantentuin and a year later he was appointed as assistant curator. With director Johannes Elias Teijsmann, they rearranged their crops to taxonomic families, which would result in the displacement of many specimens in the bot ...

Dutch East Indies
The Dutch East Indies, also known as the Netherlands East Indies ( nl, Nederlands(ch)-Indië; ), was a Dutch colony consisting of what is now Indonesia. It was formed from the nationalised trading posts of the Dutch East India Company, which came under the administration of the Dutch government in 1800. During the 19th century, the Dutch possessions and hegemony expanded, reaching the greatest territorial extent in the early 20th century. The Dutch East Indies was one of the most valuable colonies under European rule, and contributed to Dutch global prominence in spice and cash crop trade in the 19th to early 20th centuries. The colonial social order was based on rigid racial and social structures with a Dutch elite living separate from but linked to their native subjects. The term ''Indonesia'' came into use for the geographical location after 1880. In the early 20th century, local intellectuals began developing the concept of Indonesia as a nation state, and set the stage ...

Monoecious
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is connected to anemophily. It can prevent self-pollination in an individual flower but cannot prevent self-pollination between male and female flowers on the same plant. Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function. Monoecious hemp was first reported in 1929. Occurrence Monoecy is most common in temperate climates and is often associated with inefficient pollinators or wind-pollinated plants. It may be beneficial to reducing pollen-stigma interferenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
