Chenopodium

The genus Chenopodium comprises ca.100 species. They are not the most beautiful plants, but they are important. They include several food plants (C. quinoa, C. nuttalliae, C. giganteum) some are important weeds (C. album & C. polyspermum). Some have global distributions, while others are rare.


We are using the genus Chenopodium in a pilot project focusing on marking-up of taxonomic treatments and the reuse of taxonomic data. We will analyse the technical problems in the mark-up and post-processing of texts. The aim is to improve the pipeline, from digitization and OCR to import of the marked up data into a database. This is part of the pro-iBiosphere project, which is examining the technical and semantic interoperability challenges for the creation of a future biodiversity knowledge system.

The literature has been digitised in a number of ways and marked up using the GoldenGate Editor. Treatments were then uploaded in to the Plazi repository. TaxonX versions of the treatments are then uploaded into the Common Data Model (CDM) database from where the data in this website is sourced. Different kinds of treatments are being tested, from 19th century floras to modern digital publications. The pilot will pipe-clean the procedure, including testing completeness of the TaxonX XML schema and compatibility with the CDM. The mark-up has been done in cooperation with Plazi.

This website is a work in progress, but Chenopodium vulvaria is a data rich example.

The sort of the information collected on these species includes…

  • Descriptions
  • Distributions
  • Uses
  • Nomenclature
  • Literature references
  • Specimens
  • Observations

If you have any data or treatments you would like to contribute please feel free to contact us.

  • Patricia Kelbert (FUB-BGBM) the technical aspects of the import from TaxonX to CDM.
  • Sabrina Eckert (FUB-BGBM) will provide scans/pdfs from Floras and do mark-up.
  • Susy Fuentes (FUB-BGBM) Taxonomic expertise on the genus Chenopodium.
  • Quentin Groom (NBGB) has provided data and marked-up from a number of legacy floras and herbaria.
