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]
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]
Schleswig-Holstein ist in den letzten Jahrzehnten sehr gründlich auf seinen Bestand an Brombeerarten und deren Verbreitung untersucht worden, vor allem durch Hans Oluf Martensen, Anfred Petersen, Heinrich E. Weber, Werner Jansen und Eckhart Walsemann. Deren Ergebnisse wurden 1983 zusammengefasst im "Atlas der Brombeeren von Dänemark, Schleswig-Holstein und dem benachbarten Niedersachsen". Brombeeren sind in der Regel recht schwer zu bestimmen und werden deshalb von den meisten Botanikern gemieden. Diese Internet-Seite mag eine kleine Hilfe sein, dass mehr Interessierte Zugang zu den Brombeeren finden. ... [Information des Anbieters]
This web site shows drawings of Crataegus by Knud Ib Christensen; they were reproduced from his "Revision of Crataegus Sect. Crataegus and Nothosect. Crataeguineae (Rosaceae-Maloideae) in the Old World" (1992, Systematic Botany Monographs, Volume 35). [Editorial staff vifabio]
The eucalypts (the genera Angophora, Corymbia and Eucalyptus) are a botanical phenomenon unique to the Autralian continent. Nowhere else in the world does a single genus of trees dominate the vegetation of an entire continent, and nowhere else does a single genus adapt and diversify into the totality of habitats as seen across the wide diversity of the Australian countryside. This adaptation has given us a bewildering diversity of species, with over 800 at last count (and still counting!) The Eucalink pages offer a botanical tour of this diversity, from a scientific position and also from the cultural perspective, from a society that has grown up with and among these unique trees. On these pages, you will find an introduction to the eucalypts of New South Wales, with descriptions of the species, notes on distribution, ecology, images, maps and identification keys. Navigate to a searchable index of the species (with hyperlinks) by clicking on The Species button. Other buttons are self-explanatory, and provide gateways to different ways of approaching the site. While this site is focussed primarily on the eucalypts of New South Wales, some coverage is offered of the overall eucalypt group across Australia and even outside the country. ...

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. ...

Fleischfressende Pflanzen sind vom ersten Moment an faszinierend - und mit Sicherheit liegt das nicht nur an der Tatsache, dass sie das Prinzip "Tiere fressen Pflanzen" auf den Kopf stellen. Lernen Sie auf den folgenden Seiten mehr über diese geheimnisvollen Pflanzen! In unserer Karnivoren-Datenbank erhalten Sie einen Überblick über die Gattungen und Arten, über deren Kulturmethoden und Besonderheiten. Nach Möglichkeit versuchen wir, von den Arten Fotos vom Naturstandort zu veröffentlichen. ... [Information des Anbieters, verändert]
The genus Geranium (Geraniaceae) which contains about 400 species recognised, is a widespread group of vascular plants, absent only in tropical lowlands, deserts and polar regions. After Knuth’s (1912) monograph, several regional accounts as well as some detailed studies on some sections were published, but no comprehensive taxonomic treatment is nowadays available. The author of this page is involved in a new revision supported by a database system in order to improve consistence and accessibility. Considering this revision is still far from the ending, it could be useful to make some of the database available –even being not finished yet. ... [Information of the supplier]
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. ...

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]
