Catalogage et digitalisation des herbiers

Availability and access to herbarium collections.

Databsing and imaging of the whole G-DC herbarium. Apart for the specimens cited in the Prodromus, this herbarium includes the specimens cited in the Monographiae Phanerogamarum and the Piperacearum clavis analytica. Data are made available on-line through the Geneva Herbarium Catalogue (CHG).

Databasing and scanning of the nomenclatural type of the phanerogams of the general colection G. Data are made available on-line through the Geneva Herbarium Catalogue (CHG)

With an estimated 313,000 specimens the bryophyte herbarium in G is rich in historic collections such as that of Hedwig-Schwägrichen (mosses) or Franz Stephani (liverworts). If we calculate that 5 % of the bryophyte collections are types then there are an estimated 15,600 type specimens of bryophytes in G. Our recent experience with the databasing and scanning of the liverwort collection leads us to believe that this figure is an underestimate and that we are more likely to have around 20,000 types. A complete catalogue, with digital images, of the bryophyte types in G is of great value to the bryological community who can have easy access to information on type specimens as well as being of enormous value to the CJB istself for the management and long-term conservation of the collection.

The Hedwig-Schwägrichen herbarium ranks amongst the most important collections of bryophytes in the World because of its particular connection to the nomenclature of mosses and the number of types that it contains. The aim of this project is to provide a catalogue of the types in the Hedwig-Schwägrichen collection in G accompanied by digital images of the type specimens themselves and information on the original labels, protologue details and published typifications for each name. The information provided in this catalogue of types, particularly becasue it is now available on the CJB website, will hopefully facilitate the long-term conservation of these important moss specimens.
