General Description

The research programme of the CJB, focused on the main missions of exploration, conservation, research, transmission and protection, covers five main themes (Systematics and Evolution, Floras and Inventories, Ecology and Vegetation, Ethnobotany and the History of the Sciences). The scientists at the CJB conduct a wide range of research projects on plants and fungi, with the aims of:

  1. providing fundamental taxonomic and botanical data,
  2. understanding evolutionary patterns and processes, and
  3. conserving biodiversity.

Our research activities integrate our herbarium and library collections, our living collections, fieldwork activities, our laboratories and our various informatics resources and databases (Herbarium Catalogue, Geneva Botanical Information System, African Plant Names Database (, Index Hepaticarum (

We have specialists working on the Aquifoliaceae, Arecaceae, Caryophyllaceae (Silene), Gesneriaceae, Sapotaceae, lichens (Usnea) and Swiss lichens ( and mosses (Dicranaceae and Neotropical species). We are actively working on the flora of the Alps, the flora of Switzerland (including the development of a Digital Flora of Switzerland: Web-Flora for the Lichens of Switzerland), the Flora del Paraguay ( and the Flora of Corsica ( Particular areas of focus are on the floras and vegetation of South America (specifically Paraguay, Bolivia, Venezuela), Africa (specifically Madagascar, Ivory Coast) and of Switzerland.

There is an active research and conservation programme involved with the flora and vegetation of the Canton of Geneva (, especially focussing on the spatial analysis of habitats using GIS techniques.

Our research forms part of the Laboratory of Plant Systematics and Biodiversity, which is one of eight laboratories of the Department of Plant Biology of the University of Geneva. Results of our scientific activities are diffused via our scientific publications as well as through our on-line databases or project websites and popularised scientific articles.

Research Initiative

Activities and outreach with Universities
The CJB, via its Plant Systematics and Biodiversity Laboratory (, forms part of the Department of Botany and Plant Biology of the University of Geneva. A number of the CJB scientific staff give courses at the University of Geneva and participate in the Masters Programme in Biology, option Biodiversity and Systematics.


Activities and outreach with other public

The CJB, via its Environmental Education and Communication sector, offers a wide range of training activities, education activities and visits for local school children in close cooperation with the Geneva Schools Department.
