Spachea Perforata
''Spachea perforata'' is a species of flowering plants in the order Malpighiales. It is the national flower of St. Vincent and the Grenadines and is commonly known as the Soufrière tree because it can be found on the slopes of La Soufrière volcano on the island of St. Vincent. Description ''Spachea perforata'' branches in an irregular pattern. It has simple lance-shaped leaves that measure roughly long and wide. It has many small pink flowers on each stem, arranged in pendant clusters around long. While most species of Malpighiales have all hermaphroditic flowers, ''Spachea perforata'' does not, like other plants in the genus ''Spachea.'' The species appears to have the physical capabilities to reproduce asexually, but no specimen has ever been seen bearing fruit. However, the plant does prolifically produce new growth from cuttings, allowing new young trees to be grown which are generally healthy. Taxonomy History ''Spachea perforata'' was first collected in 1804 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malpighiales
The Malpighiales comprise one of the largest orders of flowering plants, containing about 36 families and more than species, about 7.8% of the eudicots. The order is very diverse, containing plants as different as the willow, violet, poinsettia, manchineel, rafflesia and coca plant, and are hard to recognize except with molecular phylogenetic evidence. It is not part of any of the classification systems based only on plant morphology. Molecular clock calculations estimate the origin of stem group Malpighiales at around 100 million years ago ( Mya) and the origin of crown group Malpighiales at about 90 Mya. The Malpighiales are divided into 32 to 42 families, depending upon which clades in the order are given the taxonomic rank of family. In the APG III system, 35 families were recognized. Medusagynaceae, Quiinaceae, Peraceae, Malesherbiaceae, Turneraceae, Samydaceae, and Scyphostegiaceae were consolidated into other families. The largest family, by far, is the Euphorbiaceae, ...

Floral Emblem
In a number of countries, plants have been chosen as symbols to represent specific geographic areas. Some countries have a country-wide floral emblem; others in addition have symbols representing subdivisions. Different processes have been used to adopt these symbols – some are conferred by government bodies, whereas others are the result of informal public polls. The term floral emblem, which refers to flowers specifically, is primarily used in Australia and Canada. In the United States, the term state flower is more often used. National plants Africa Mauritius The national flower of Mauritius is '' Trochetia boutoniana''. Seychelles The national flower of the Seychelles is the tropicbird orchid (known locally as ''orkid payanke''), '' Angraecum eburneum''.

Saint Vincent (Antilles)
Saint Vincent is a volcanic island in the Caribbean. It is the largest island of the country Saint Vincent and the Grenadines and is located in the Caribbean Sea, between Saint Lucia and Grenada. It is composed of partially submerged volcanic mountains. Its largest volcano and the country's highest peak, La Soufrière, is active, with the latest episode of volcanic activity having begun in December 2020 and intensifying in April 2021. There were major territory wars between the indigenous population of the Black Caribs, also called the Garifuna, and Great Britain in the 18th century, before the island was ceded to the British in 1763 and again in 1783. Saint Vincent and the Grenadines gained independence from the United Kingdom on 27 October 1979 and became part of the British Commonwealth of Nations thereafter. Approximately 130,000 people currently live on the island, and the population saw significant migration to the UK in the early 1900s and between the 1940s and 1980s. T ...

Hermaphroditic Flower
Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants (green algae, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it was understood that the pollination process involve ...

Cutting (plant)
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings. Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Anderson (botanist)
Alexander Anderson (1748 – 1811) was a Scottish surgeon, explorer and botanist who worked as Superintendent to the Botanical Garden on the Windward Island of Saint Vincent from 1785 to 1811. Early life and education Born in Aberdeen, Anderson later studied at the University of Edinburgh, where he was tutored by William Cullen (professor of medicine and chemistry) and John Hope (professor of botany and materia medica). Fellow Aberdonian William Forsyth briefly employed him at the Chelsea Physic Garden in London, prior to Anderson's emigration to New York in 1774, where he stayed with his brother John, a printer. After a petition was lodged by physicians William Wright and Thomas Clarke of Jamaica in 1798, Anderson was awarded an honorary 'Degree of Doctor in Physick' from the University of St. Andrews. The petition identified him 'assistant surgeon to his Majesty's forces in St. Vincent' and confirmed he had been 'educated in Scotland' with knowledge 'in all branches of ...

Antoine Laurent De Jussieu
Antoine Laurent de Jussieu (; 12 April 1748 – 17 September 1836) was a French botanist, notable as the first to publish a natural classification of flowering plants; much of his system remains in use today. His classification was based on an extended unpublished work by his uncle, the botanist Bernard de Jussieu. Life Jussieu was born in Lyon, France, in 1748, as one of 10 children, to Christophle de Jussieu, an amateur botanist. His father's three younger brothers were also botanists. He went to Paris in 1765 to be with his uncle Bernard and to study medicine, graduating with a doctorate in 1770, with a thesis on animal and vegetable physiology. His uncle introduced him to the Jardin du Roi, where he was appointed as a botany Demonstrator and deputy to L. G. Le Monnier, professor of botany there in 1770. Le Monnier had succeeded Antoine-Laurent's uncle Antoine in 1759. Lectures by eminent botanists, including the Jusssieu dynasty were popular there, especially among pha ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
