Conservatoire et Jardin botaniques de la Ville de Genève



For over 20 years, the Conservatory and Botanical Garden of the City of Geneva have continued to invest in the development of what we now call the Geneva’s Botanical Information System (SIBG), an management tool used for the management of the scientific projects, the herbarium collections and the living collections of our institution. From the SIBG are extracted the majority of the information available online through the different databases listed below

Botalista : a new open source management tool

Because the SIBG is based on fee-paying technologies and obsolete today, CJB decided to develop a new management tool based solely on open source software.

Ultimately, this new tool, called BOTALISTA, will be offered to other interested botanical institutes.

The Herbarium Catalogue

With around 6 million specimens, the herbarium of the Conservatory and Botanical Gardens of the City of Geneva (CJB) is one of the most important in the World. Based on a long tradition of botanical research and exploration in Geneva dating back to the 18th century, the institution houses plants and fungi from all over the World, but in particular from the Mediterranean region, the Near and Middle East and South America as well as from the European flora. This virtual catalogue (SIGB) provides access to all databased specimens from our large herbarium collection.

Data base of African Flowering Plants APD

African Plant Database was developed with a collaboration between Geneva botanical garden and
South African National Biodiversity Institute (SANBI), it was first a merging of southern and tropical Africa data, and then we added Madagascar plants with a collaboration of Missouri botanical garden, and last, with the north Africa data by Dobignard, associated researcher.
The database contain c. 200'000 names, 300'000 bibliographic links and 1'000'000 distribution occurrences, with the aim to understand plant distribution and ecology in Africa.
The taxonomical and nomenclatural values were recognised by AETFAT as a standard, by OPTIMA and the WCB in 2011 in Melbourn, its necessary to exchange, share and analyse all botanical informations.

Eflora Maghreb (in French)

Floras are main tools for evaluate and preserve biodiversity. The objective of this project is to made available readily on the web a document to identify plants of Algeria, and then for all maghreb. (c. 6400 taxa) Flora of Algeria, published in 1963 by Quézel et Santa, is unavailable since many years, and a lot of changes and new discoveries occurred. The new technologies allow to share and update in live the data, a lot of images, drawings, maps and descriptions can be used to document a flora, and developing a dynamic among young generations of botanists or a larger public. This project should be a collaboration between tunisian, algerian, moroccan, swiss, spanish and french institutions, and should promote new field studies.

Catalogue of the Hedwig types – Herbarium of bryophytes

During the International Botanical Congress of 1910, the 1801 publication of Johannes Hedwig, "Species Muscorum Frondosorum", was designated as the starting point for the nomenclature of mosses (bryophytes), excepting the Sphagnaceae. This virtual catalogue is a guide to the types, or possible types, present in the Hedwig herbarium in Geneva that have been entered into the SIBG database.

Part 1. Type material and a review of typifications for the Hedwig moss names.

Index Hepaticarum Names Database

Index Hepaticarum lists all of the epithets of liverworts and hornworts published between the effective dates of the 1st May, 1753 (the date of the start of nomenclature for liverworts and hornworts) and the 31st December, 1973. The objective of this project is to facilitate research around the World on the taxonomy and the systematics of liverworts and hornworts, by providing access to names, authors, references and information on types. The series Index Hepaticarum (14 volumes in all) contains more than 30,000 epithets of specific and infraspecific rank published between 1753 and 1973. All of the species and sub-species names, published from 1974 onwards are contained in supplements complied by J. Engel (F). Collectively, this work represents an incomparable resource for liverwort and hornwort systematics around the World.

Catalogue of the lichens of Switzerland (in French)

The Catalogue of the Lichens of Switzerland collates the literature reports of all the lichens growing in Switzerland today. It is an updated and online version of the publication "Les champignons lichénisés de Suisse" that appeared in Cryptogamica Helvetica 19 in 2004, edited by Bryolich and sponsored by the Swiss Academy of Sciences. For each species the catalogue provides information on distribution at the cantonal level as well as within the natural zones of Switzerland, altitudinal distribution, ecology (substrate) and a list of publications where the presence of it in Switzerland was mentioned. This catalogue is the reference source that has been used to develop the project "Digital Lichen Flora of Switzerland at the CJB.

Project Hyphaene

This is the site of the project Hyphaene one of the research activities undertaken by the Conservatory and Botanical Garden of Geneva towards the study of African palms. The information here presented aims to expand our current knowledge of the enigmatic genus of the widely known "Doum" palms, Hyphaene (7-8 species), which ranks among the most economically important, yet extremely poorly known African palm genera. The genus was monographed about 90 years ago, and our project aims to undertake modern taxonomic, morpho-anatomical, phylogenetic, ethnobotanic, ecological and conservation studies of the group. Our broad initiative on the study of African palm taxa is part of the 50 projects associated to the 2012-2016 African program of the University of Geneva.

Auxilium ad botanicorum graphicem (in French)

This virtual catalogue contains examples of the handwriting of botanists that were published in journal Candollea between 1972-1979. These examples serve principally to assist researchers in the interpretation of hand-written notes and annotations in the herbarium. In general, the examples contain the signature and handwriting, in various languages, of each of the chosen botanists, as well as an example of a label from their personal herbarium. In addition to the handwritten examples, this catalogue provides biographical information on the botanist in question, including published reference/s on their biographies. Where possible, the location of their collections is provided using a simplified system of the codes in Index Herbariorum.

Database of the plants of Brazil in TAPIR (service web)

This Web service facilitates access to all the Brazilian specimens in the herbarium of Geneva. This service uses the TAPIR protocol, developed by the Taxonomic Database Working Group (TDWG), and which allows the exchange of standardized nomenclatural data.
An example of Tapir query:
