Dipteris Chinensis
''Dipteris'' is a genus of about seven species of ferns, native to tropical regions across the world, particularly Asia, with a species in northeastern Queensland in Australia. It is one of two genera in the family Dipteridaceae. Description Species of ''Dipteris'' grow from creeping rhizomes, and have large stalks to the sporangium and annulus. The rhizomes have bristles (or hairs) and the fronds have uniseriate hairs (having one line or series). All species of ''Dipteris'' have spore-capsules that are carried on the lower surface of the broad lobed frond.A. C. Seward The fronds can reach up to 50 cm long. Taxonomy Caspar Georg Carl Reinwardt first published the genus in 1825, by describing ''Dipteris conjugata'' Reinw. which is the best known species. In 1839, R. Brown reduced the genus to a subgenus of ''Polypodium''. In 1901, Konrad Christ published ''Die Farnkrauter der Erde't'', within which he included the genus ''Dipteris'' in the family Polypodiaceae, (a subdivi ...

Caspar Georg Carl Reinwardt
Caspar Georg Carl Reinwardt (5 June 1773 in Lüttringhausen – 6 March 1854 in Leiden) was a Germans, Prussian-born Netherlands, Dutch botanist. He is considered to be the founding father of Bogor Botanical Garden in Indonesia. Biography In 1787, he was apprenticed to an Amsterdam pharmacy where his brother worked. He came in contact with several scientists, including the botanist Gerardus Vrolik (father of Willem Vrolik). He had his education at the Athenaeum Illustre of Amsterdam, Athenaeum Illustre where he successfully engaged in the study chemistry and botany. Under the Batavian Republic and the Kingdom of Holland he served as a professor of natural history at the University of Harderwijk from 1800 to 1808. After a while he became associate professor of chemistry and pharmacy. In 1808, he appealed to king Louis Bonaparte and was offered work as director of the "to be built" botanical and zoological gardens and museums. In 1808, he became a member of the Royal Netherl ...

Stomata
In botany, a stoma (: stomata, from Greek ''στόμα'', "mouth"), also called a stomate (: stomates), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange between the internal air spaces of the leaf and the atmosphere. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that regulate the size of the stomatal opening. The term is usually used collectively to refer to the entire stomatal complex, consisting of the paired guard cells and the pore itself, which is referred to as the stomatal aperture. Air, containing oxygen, which is used in respiration, and carbon dioxide, which is used in photosynthesis, passes through stomata by gaseous diffusion. Water vapour diffuses through the stomata into the atmosphere as part of a process called transpiration. Stomata are present in the sporophyte generation of the vast majority of land plants, with the exception of liverworts, as well as so ...

India
India, officially the Republic of India, is a country in South Asia. It is the List of countries and dependencies by area, seventh-largest country by area; the List of countries by population (United Nations), most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ...

Thomas Moore (botanist)
Thomas Moore (21 May 1821 – 1 January 1887) was a British gardener and botanist. An expert on ferns and fern allies from the British Isles, he served as Curator of the Society of Apothecaries Garden from 1848 to 1887. In 1855, Moore authored ''The Ferns of Great Britain and Ireland.'' Life He was born at Stoke next Guildford, Stoke, near Guildford, Surrey, on 21 May 1821. He was brought up as a gardener, and was employed at Fraser's Lee Bridge Nursery, and subsequently, under Robert Marnock, in the laying out of the Regent's Park gardens. In 1848, by the influence of Dr. John Lindley, he was appointed curator of the Apothecaries' Company's Garden at Chelsea, in succession to Robert Fortune, an appointment which gave him leisure for other work. Under Moore's tenure during the period of so-called "pteridomania", the garden increased the number of fern species cultivated there by fifty percent and was renamed the Chelsea Physic Garden in 1875. The Thomas Moore Fernery was built i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...
