This website is the most comprehensive online resource available for the flora of Angola. The data thus far have been compiled with input from 32 contributors, based initially on the book Plants of Angola (Figueiredo & Smith 2008). These data include all taxa known to occur in Angola, synonyms, species descriptions and distribution data, type specimens (most types from Angola are included), data from other representative specimens, images and literature.
The genus Aster L. (Asteraceae) was described by Linnaeus (1753, Sp.Pl.; 1754, Gen. Pl.), and originally comprised numerous species that are now segregated to other genera. The main centers of diversity and speciation are in the North America, the Caucasus and some other regions. According to various sources, the genus Aster s.l. comprises from 250 to 300 species that spread in Eurasia, Africa, the Americas (extratropical regions). By some estimates, of the kind in the broadest sense includes about 600 species. After 1990s genetic studies confirmed segregation of the North American group.
The importance of Bobart's Hortus Siccus is that it is a snapshot of a botanical collection made during an exciting period of Early Modern botanical investigation, provides a means of verifying the identities of names used in the two 'Catalogues' published for the Oxford Botanic Gardens in 1648 and 1658 and illustrates the range of plants that were being grown during the period. Furthermore, the specimens in the Hortus Siccus reveal interesting applications of common names and Druce credits the collection as containing some of the first Oxfordshire records of native British plants.
The Herbário IAN, supporting research in the Eastern Brazil Amazon region, is part of Embrapa Amazionia Oriental. It is one of the three largest herbaria in Amazonian Brazil and was the first herbarium in Brazil to adopt BRAHMS. Most of the specimens are now databased and imaged and are gradually being uploaded to this website. The herbarium has over 191.000 herbarium specimens with at least 2000 type specimens. They have a xylarium has about 8000 wood samples and a library with over 30,000 photographs and illustrations.
This 'Cyber-monograph' website provides detailed information on the entire papaya's family. Specifically, data are provided on taxonomy, morphology, reproduction (sexual systems and sex chromosomes), evolutionary relationships , distribution ranges, and biogeography (e.g., how they reached South America from Africa and diversified there). In addition to Carica papaya, I provide detailed information on all wild members of the Caricaceae, including the so-called highland papayas from the Andes (Vasconcellea species) and the closest wild relatives of papaya from Mexico, Guatemala, and El Salvador.
Early eighteenth-century North America was an exotic place for British naturalists to explore. Regular links between London and the New World meant all manner of natural history treasures were being brought back to London. Mark Catesby (?1682-1749) was one of many naturalists who sent objects from North America to Europe.
The website provides access to data for nearly 37,000 conifer herbarium records gathered from all continents and all conifer families. Records, unless introduced or cultivated, can be mapped. Taxonomic information is provided with full synonymy, citation and types.
This database, the most comprehensive resource of its type for Gabon, contains over 65,000 specimens, about 90% of all plants known to have been collected in Gabon. Over 98% of these records include accurate map references.
In the Historia Muscorum, Dillenius attempted to enumerate all of the 'lower plants' that he knew in 576 pages of Latin text and 85 plates. As with the Hortus, the plates were drawn and engraved by Dillenius. The Historia Muscorum comprises 20 Dillenian 'genera' in the main text and an additional four 'genera' in the Appendix.
The Leucaena database includes data from ca 3,000 specimen records from 26 herbaria (A, AAU, BISH, BM, CAS, CR, EAP, F, FHO, G, HAL, HEH, K, LAGU, M, MEXU, MO, NY, OXF, PMA, QAME, TEFH, TEX, UC, US and W) along with detailed field notes, common names, phenology and wild/cultivated codes, and duplicate records, and the majority of specimens (2393) have accurate geographical data.
Lobostemon is endemic to the southern tip of Africa, mainly confined to the winter-rainfall area of South Africa, occurring from Springbok to Mossel Bay, and further eastward along the coast to about Grahamstown, where the rain occurs throughout the year.
The Mascarenes are composed of the islands of Réunion and Mauritius and Rodrigues. Together with Madagascar, Comoros and the Seychelles, it forms part of the Western Indian Ocean Islands Biodiversity Hotspot.
The NHN herbarium database has been built over the years for various purposes and from various sources. The majority of records relate to specimens present in one of the NHN herbaria (L, U & WAG). The database also contains records of duplicates that have been sent to other herbaria, of materials databased for taxonomic revisions, and of specimens collected in areas of special interest for NHN (for instance Gabon) that were databased for that reason. Some data that were incorporated from external data sources may not be visible on this website.
The Fielding-Druce and Daubeny herbaria and the xylarium, collectively known as the Oxford University Herbaria, currently contain 800,000-1,000,000 botanical specimens from across all taxonomic groups and geographic regions. The collections contain at least 25,000 types.
The 25th July 2021 marks 400 years of botanical research and teaching by the University of Oxford. As a celebration and count-down to this anniversary, the University of Oxford Botanic Garden and Harcourt Arboretum, together with the Oxford University Herbaria and the Department of Plant Sciences, will highlight 400 plants of scientific and cultural significance. From November 24th 2013, one plant will be profiled weekly, enabling you to see images associated with the plant from Oxford University's living and preserved collections.
The MAPR bryophyte collection started in 1993 and is maintained by Inés Sastre-De Jesús. Although the bulk of this collection is specimens from Puerto Rico and the Dominican Republic it also contains specimens from most Latin American countries, especially South America. The collection also has Fasciles 1-8 of Bryophyta Neotropica Exsiccata edited by S. R. Gradstein.
The UPRRP herbarium, with over 43,000 specimens including Tracheophytes, Bryophytes, Algae and Fungi, is set up as a reference collection not only for Puerto Rico, but also for the whole Caribbean Basin.
This website provides access to the specimens, images and literature of the Sibthorpian Herbarium. This Herbarium is traditionally recognised as the last of the historic herbaria in Oxford University Herbaria. Importantly, it contains all of the plant specimens collected by John Sibthorp (1758-96) on his eastern Mediterranean expeditions which are associated with the Flora Graeca (1806-40).
Criado em 1974 por docentes do Departamento de Botânica do Instituto de Biologia da Unicamp, o Herbário UEC passou a órgão complementar do IB em 2008, sendo hoje um importante centro de pesquisa e ensino para ...
The UKOTs Online Herbarium project has been developed to provide easy access to UKOT plant species and specimen information to help UKOT Governments meet targets of the Global Strategy for Plant Conservation (GSPC), specifically targets 1 and 2.
