Samadera Bidwillii
''Samadera'' is a genus of four species of plants belonging to the family Simaroubaceae in the order Sapindales. Its range is from eastern Africa through tropical Asia to eastern Australia. Type species: ''Samadera indica'' Gaertn Description Plants in this genus are large or small trees with simple leaves. The flowers are bisexual, produced in axillary or terminal umbels. The calyces (collective name for the sepals) are small, 3-5 partite (divided into parts) and imbricate (overlapping each other). The 3-5 petals are much longer than the calyx, they are coriaceous (leather-like, stiff and tough) and imbricate. The flower disk is large, conical, with 8-10 stamens, including in the corolla, with a small scale at the base. The stigmas are acute and the ovules are solitary and pendulous. The fruit (or seed capsule) consists of 1-5 large dry compressed 1 seeded drupes (stone fruit), each with a narrow unilateral wing.Edmund Gregory Taxonomy It was first published and described by ...

Joseph Gaertner
Joseph Gaertner (12 March 1732 – 14 July 1791) was a German botanist, best known for his work on seeds, ''De Fructibus et Seminibus Plantarum'' (1788-1792). Biography He was born in Calw, and studied in Göttingen under Albrecht von Haller. He was primarily a naturalist, but also worked at physics and zoology. He travelled extensively to visit other naturalists. He was professor of anatomy in Tübingen in 1760, and was appointed professor of botany at St Petersburg in 1768, but returned to Calw in 1770. Gaertner made back cross to convert one species into another. Back cross increases nuclear gene frequency His observations were: 1. Dominance of traits 2. Equal contribution of male and female to the progeny 3. No variation in F1 (first generation of descendants) 4. Large variation in F2 (second generation of descendants) including parental and intermediate types 5. Some of F2 plants had entirely new traits but he was unable to give possible explanation for observed dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simaba
''Simaba'' is a genus of flowering plants belonging to the family Simaroubaceae. Its native range stretches from southern tropical America and Trinidad, across to western tropical Africa to Angola then across to western Malesia. It was first published by French botanist Jean Baptiste Christophore Fusée Aublet (1720–1778), in Hist. Pl. Guiane on page 409 in 1775. Hans Peter Nooteboom (1934–2022) in 1962 (published in 1963), took a very broad view of the genus ''Quassia'' and included therein various genera including, ''Hannoa'' , '' Odyendyea'' , ''Pierreodendron'' , ''Samadera'' , ''Simaba'' and ''Simarouba'' In 2007, molecular analyses of the Simaroubaceae family (Clayton et al., 2007), suggested the splitting up of genera ''Quassia'' again, with all Nooteboom's synonyms listed above being resurrected as independent genera. Species As accepted by Plants of the World Online; *'' Simaba africana'' *'' Simaba borneensis'' *''Simaba guianensis'' *'' Simaba monophylla' ...

Samadera Indica
''Samadera indica'' (syn. ''Quassia indica''), the bitter wood or Niepa bark tree, is a species of plant in the family Simaroubaceae. It is a shrub or tree and grows primarily in wet tropical regions, from west Africa, through India, then down through Indonesia to Malesia. It is used in folklore medicine in various Asian countries as well to treat various ailments such as malaria, fevers, rheumatism, bruises, skin conditions and others conditions. The leaves are used as insecticides against termites, and the wood is used for knife handles. Description ''Samadera indica'' is an evergreen tree or shrub,Umberto Quattrocchi. CRC World Dictionary of Medicinal and Poisonous Plants. CRC Press, p.45:2012. that can grow up to tall, or tall. It has pale yellow Bark (botany), bark, which is transversely cracked.

Sinhala Language
Sinhala ( ; Sinhala: , , ), sometimes called Sinhalese ( ), is an Indo-Aryan language primarily spoken by the Sinhalese people of Sri Lanka, who make up the largest ethnic group on the island, numbering about 16 million. It is also the first language of about 2 million other Sri Lankans, as of 2001. It is written in the Sinhalese script, a Brahmic script closely related to the Grantha script of South India. The language has two main varieties, written and spoken, and is a notable example of the linguistic phenomenon known as diglossia. Sinhala is one of the official and national languages of Sri Lanka.

World Flora Online
World Flora Online is an Internet-based compendium of the world's plant species. Description The World Flora Online (WFO) is an open-access database, launched in October 2012 as a follow-up project to The Plant List, with the aim of publishing an online flora of all known plants by 2020. It is a project of the United Nations Convention on Biological Diversity, with goal of halting the loss of plant species worldwide by 2020. It is developed by a collaborative group of institutions around the world in response to the 2011–2020 Global Strategy for Plant Conservation (GSPC)'s updated Target 1: to produce "an online flora of all known plants". An accessible flora of all known plant species was considered a fundamental requirement for plant conservation. It provides a baseline for the achievement and monitoring of other targets of the strategy. The previous target of GSPC was achieved in 2010 with The Plant List. WFO was conceived in 2012 by an initial group of four instituti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
