In Bulgaria, Genus Alchemilla consists of 35 species so far. Globally, the genus, which is of Family Rosaceae, comprises about 1000 species. In Europe, they are more than 300. The interspecies hybridization and facultative apomixis (asexual seed development) have caused the high morphological variability of the species. That has troubled botanists for ages when relating a specimen to known species and has brought about more and more new species. ... [Information of the supplier]
The site Melastomataceae.Net will present information on the biodiversity of these two families by providing a portal to open-access databases, starting with MEL names. MEL names is a service for accessing the ca. 13,278 names of Melastomataceae and Memecylaceae with information on recognized species, synonymous names, and literature; MEL occurrence will deliver data on distribution of species and genera. It is planned for the future and will offer special search options, e. g. in connection with ecological data of tropical biomes. In the meantime, the Occurrences search of the GBIF portal is recommended. Please try the advanced seach options there. ... [Information of the supplier]
Finde den Wiesenknopf ist eine Citizen Science Aktion zum Wissenschaftsjahr 2012 - Zukunftsprojekt ERDE. Das Helmholtz-Zentrum für Umweltforschung (UFZ) nutzt den Rahmen des Wissenschaftsjahres, um die Monitoring-Aktion "Finde den Wiesenknopf" zu starten. Die in der Aktion erhobenen Daten sollen Aufschluss geben über die aktuelle geografische Verbreitung des Großen Wiesenknopfes und seine Rolle im Ökosystem Wiese. Die Teilnehmer des Projekts suchen nach Vorkommen des Großen Wiesenknopfes Sanguisorba officinalis, einer typischen Grünlandpflanze, die von vielen Insekten als Nahrungspflanze genutzt wird. Die Koordinaten der Fundorte und Fotos werden hier auf unserer Webseite registriert. Das Projekt wurde am 1. Mai 2012 gestartet. Wie können Sie an der Aktion teilnehmen? Halten Sie Ausschau nach dem Großen Wiesenknopf Sanguisorba officinalis. Erfassen Sie die geografischen Koordinaten des Vorkommens (des ungefähren Mittelpunkts) und schätzen Sie, welche Fläche das Vorkommen einnimmt. Die Verteilung von Einzelpflanzen z.B. auf einem Deich kann verbal beschrieben werden. Falls möglich, fotografieren Sie die Besucher des Wiesenknopfes, die blütenbesuchenden Insekten. ...

Dean Nicolle is a consultant arborist, botanist and ecologist specialising in the systematics and ecology of the eucalypts (genera Angophora, Eucalyptus and Corymbia) and in the arboricultural assessment of trees. Currency Creek Arboretum is a specialist eucalypt arboretum ('zoo of trees'), with its main purpose being research into Australia's most dominant natural group of plants, the eucalypts. The arboretum has the largest collection of eucalypt species in the world, with over 900 species and subspecies (and over 7000 individual plants) having been planted on the site. The arboretum has been established and is managed by Dean Nicolle. ... [Information of the supplier]
Legumes play vital roles in maintaining nitrogen cycle of biosphere and in agriculture for nitrogen fixation by their unique ability to carry out symbiotic nitrogen fixation (SNF) through endosymbiotic interactions with bacteria in root nodules. This vital feature can't be studied by using the model plant Arabidopsis thaliana. Besides the root nodulation and symbiotic nitrogen fixation with rhizobia, legumes possess several unique features that are not found in A. thaliana, such as mycorrhization, compound leaf development, protein-rich physiology, a profuse secondary metabolism, glandular trichome development, and border cells in roots. LegumeIP is an integrative database and bioinformatics platform for comparative genomics and transcriptomics to facilitate the study of gene function and genome evolution in legumes, and ultimately to generate molecular based breeding tools to improve quality of crop legumes. ...

Legumes of the World Online (LOWO) is part of RBG Kew’s commitment to advance the knowledge and understanding of the approximately 750 genera of the legume family. LOWO is based upon the book Legumes of the World published by RBG Kew in 2005 which is transformed here into a web resource offering expanded and updated information about legume genera. The Legume Research Team at RBG Kew manages and updates LOWO through collaboration with an international community of legume systematic botanists. Users of LOWO can browse and search for information about legume genera through the traditional subfamily-tribe-genus hierarchy or within a modern phylogeny-based classification. ...

This site concerns Amelanchier, a member of the Rosaceae (rose) family. The purpose of this site is to present information about the systematics and evolution of these attractive small trees and shrubs, which are commonly called shadbushes, serviceberries, juneberries, sugarplums, and numerous other common names. Amelanchier grows primarily in early successional habitats of the North Temperate Zone. The genus is most diverse taxomically in North America, especially in the northern United States and southern Canada, and is native to every state of the United States except Hawaii. These plants are valued horticulturally, and their fruits are important to wildlife. The systematics (taxonomy) of shadbushes has long perplexed botanists, horticulturalists, and others, as suggested by the range in number of species recognized in the genus from 6 to 33 in two recent publications (Landry 1975, Phipps et al. 1991; see references on Systematics page). A major source of complexity comes from the occurrence of apomixis (asexual seed production), polyploidy, and hybridization (see Evolution page). ... [Information of the supplier]
Researchers in legume taxonomy and systematics from around the world have joined forces to advance and propose a new updated family classification. In this context, the Legume Morphology Working Group (LMWG) was created primarily to contribute to the identification of morphological characteristics that are taxonomically and phylogenetically useful. The international symposium and workshop “Legume Morphology: Current Knowledge and Future Directions” is an important step towards achieving the general objectives of the LMWG: i) to support the work of the Legume Phylogeny Working Group (LPWG) towards developing the new classification of Leguminosae; ii) to evaluate how comparative morphological studies may help to better understand species groups, and poorly-resolved molecular phylogenetic relationships; iii) to identify gaps in our knowledge about legume morphology and coordinate efforts to fill these gaps; and, finally, iv) to promote consistency in legume morphological terminology for effective communication in the legume community, through an illustrated glossary including definitions that can be used widely as a standard reference. This event represents the first time that legume researchers focusing on legume morphology in and beyond South America reunite to advance legume systematics in a coordinated way. Furthermore, this event would be hosted by one of the countries with the highest legume diversity worldwide (221 genera and 2.800 species listed in the Flora of Brasil) and a long tradition of legume research. ...
