Work on the DELTA Euphorbiaceae key started in 2002 as a one-year undergraduate project. The generic descriptions in Genera Euphorbiacearum, comprising Centroplacaceae, Euphorbiaceae senu stricto, Pandaceae, Phyllanthaceae, Picrodendraceae, and Putranjivaceae, were digitised and further standardised. Aimeé Galster also illustrated each character state where possible. Over the following years the key was tested and continually improved in the Malpighiales Section of the Kew Herbarium during routine naming sessions. The size and diversity of Euphorbiaceae sensu lato, and the wealth of data contained in this key is such that it is far from perfect, but testing by more specialists will hopefully further improve the accuracy of the database behind the key. The Kew Malpighiales Team welcomes any comments and corrections from users, and will regularly integrate them in updates. ... [Information of the supplier]
The Malvaceae Info web site provides information, both botanical and horticultural, on the angiosperm family Malvaceae sensu APG (which includes the traditional Bombacaceae and much of the traditional Sterculiaceae (± Byttneriaceae) and Tiliaceae), together with a little material on related families in the order Malvales and of general botanical content. The traditional Malvaceae sensu strictu consists of the mallows, abutilons, cotton, hibiscuses and related plants; the extended family Malvaceae sensu APG also contains baobabs, balsa, kapok, kola, cacao, jute, limes (lindens), durians and a wide variety of other plants. Malvaceae Info is targeted at botanists, natural historians, horticulturalists and gardeners. ... [Information of the supplier]
The Arabidopsis Book (TAB), ISSN: 1543-8120, represents a new mode of communication between researchers and a new model for scientific publishing. TAB is envisioned as a compilation of over 100 invited chapters, each reviewing in detail an important and interesting aspect of the plant Arabidopsis thaliana, with reference to what is known in other plants and in other kingdoms. TAB is available only via the internet and is free of charge. The American Society of Plant Biologists is providing funds for the mounting and maintenance of TAB as a public service. ...

The gallery is meant to eventually exhibit a photograph of every known species of Androsace. I have applied the George Smith and Duncan Lowe taxonomy system, set out in their “The Genus Androsace” publication. Several conclusions reached by Alarich Kress in 1997 and 1999, as a result of his detailed research into Spanish Androsaces for “Flora Iberica”, served as guidelines. Natural hybrids are listed alphabetically, but are preceded by an "X". Any known subspecies and varieties comes together with the main species, in the way of a group. Many photographs shown here will be of Androsaces growing in the wild. Others will feature garden-grown specimens. ... [Information of the supplier]
Many invasive species, like Garlic Mustard (Alliaria petiolata), are threatening the world's natural resources, but the abundance of invasive species can vary dramatically over space and time. Scientists still do not have a good understanding of why this is so. Through large-scale sampling, scientists can identify areas that differ in the intensity of invasion and try to understand why these differences exist. We can also compare this to variation in the native range. This may be crucial to researching new methods of control, but a large project like this could cost millions of dollars and years of work. Through the use of a simple, standardized protocol, volunteers can help to generate valuable scientific data. Participating in this research does not require specialized training. ...

This Webpage of the International Euphorbia Society is dedicated to the furtherance of knowledge of plants of the Euphorbiaceae and of their cultivation. Euphorbiaceae is the name given to one of the largest families in the plant world, sometimes known as spurges. It includes around 300 genera and 7,500 species, and of these around 870 are regarded as succulent. The IES is mostly concerned with the succulent genera: Euphorbia, Monadenium, Synadenium, Elaeophorbia, Endadenium, Pedilanthus, Jatropha and Cnidoscolus. ... [Information of the supplier, modified]
The aims of the Lacistemataceae electronic monograph is to: 1. aggregate knowledge on Lacistemataceae from all scientific areas into this website and associated Lacistemataceae Holistic Database (LHD); 2. provide freely and easily accessible information for preservation of this family within its natural habitat and botanical gardens situated within its natural distribution range. Current classification is as follows: Domain: Eukarya; Kingdom: Viridophyta; Phylum: Magnoliophyta; Eudicots; Core Eudicots; Rosids; Eurosids I; Order: Malpighiales; Family: Lacistemataceae (APG II 2003). ...

This website is for people interested in identifying species Primulas. There are over 3000 images in the Species Gallery! The gallery will display photographs of all Primula species, subspecies and varieties. Taxonomy follows currently accepted naming. Resources include John Richards' book Primula, The Flora of China, The Flora of Bhutan vol2, part2, and The Flora of North America. Natural hybrids are displayed with the species.

BrassiBase is a developing online-accessible knowledge and database system of cross-referenced information and resources on Brassicaceae (Cruciferae) taxonomy, systematics and evolution, including chromosome numbers, traits and characters, germplasm resources, and accurate enumeration of all species, genera and tribes. Biological, molecular and evolutionary knowledge is exponentially increasing in the mustard family. However, because of the complex and overwhelming biological diversity of the family, it is difficult to assess research results within a larger evolutionary framework. Many species have been proven to be remarkable study objects but are rarely available. Biological material and resources, either collected directly in the wild or held in germplasm collections, have often been taxonomically misidentified; and only very rarely has the material been further characterized and documented. There is also no comprehensive survey of character and trait distribution among Brassicaceae lineages, though family-wide phylogenies are meanwhile available. In order to close these gaps, we will make accessible to the scientific community the research data focusing on adaptive characters and their evolution in the Brassicaceae. In this context, we will also provide a comprehensive documentation of the taxonomy and systematics of the entire family. This will include a database with all relevant taxonomic, systematic and phylogenetic literature, a comprehensive data collection of characters and traits, a DNA-based identification tool for genera and species, electronic interactive keys for the identification of genera and species, and a setup of a carefully selected and documented germplasm collection representing main lineages of the family. This knowledge database, hereafter BrassiBase, has been launched within the framework of the DFG priority programme SSP 1529 “Adaptomics − Evolutionary plant solutions to ecological challenges/Molecular mechanisms underlying adaptive traits in the Brassicaceae s.l.”. ...
