There are four websites that provide substantial data on gesneriad genera. These are:

A. Weber & L.E. Skog (2007 onw.): The genera of Gesneriaceae. Basic information with illustration of selected species. Ed. 2. [A revision (ed. 3) is in preparation].

Apart from some general information (the family Gesneriaceae, historical and present classifications, links to other websites etc.), each genus of the family is treated in a standard form. Information includes the following items:

  • Name and original publication of the genus
  • Etymology
  • Synonyms
  • Infrafamilial position (according to Weber et al. 2013)
  • Description of the genus
  • Chromosome number
  • Type species
  • Species number
  • Species names (electronic link to Skog & Boggan’s World checklist of Gesneriaceae)
  • Distribution
  • Ecology
  • Notes (e.g., on taxonomic history, special characters, subdivision of genus, state of study, pollination syndrome, seed dispersal etc.
  • Selected references (citations in short form)
  • Bibliography (electronic link to Skog & Boggan’s Bibliography of the Gesneriaceae)
  • Illustrations [image(s) of one or several species (whenever possible including type species). [Pictures can be magnified by clicking the picture area]

L.E. Skog & J.K. Boggan (last updated 2011): Gesneriaceae Research. World Checklist of Gesneriaceae.

The World Checklist of Gesneriaceae culminates efforts at the Smithsonian Institution to record a complete list of names that have been published in the Gesneriaceae and to determine the current status of each name. All names known to be described in Gesneriaceae have been compiled in a single searchable list.

The World Checklist is no longer updated, as of this writing in early 2017. It remains an indispensable source of names, synonomies and other taxonomic information occurring up to 2007, and may be updated in the future.

Via the Checklist query page the requested information can be ordered by typing or selecting a generic name, an author name or a keyword.

L.E. Skog & J.K. Boggan (last updated 2007): Gesneriaceae Research. Annotated Bibliography of Gesneriaceae

The Bibliography of the Gesneriaceae was developed to facilitate taxonomic research on Gesneriaceae. The Bibliography had its origin in a collection of papers on Gesneriaceae started by Conrad V. Morton and continued by Laurence E. Skog. The Bibliography is maintained as a database with new references being continuously added from the current literature, as well as references from the older literature when they are discovered. A searchable version presented here will be updated periodically.
Though the website is no longer updated, it provides significant information on the literature that has been published until 2007.

M. Möller & M. Pullan (2015 onw.): RBGE ‘WebCyte2’ – An updated Gesneriaceae cytology database.

This is a database dedicated to assist research into the cytology of members of the family Gesneriaceae. ‘WebCyte2’ is an update of ‘WebCyte’ and takes account of all taxonomic changes based on recent systematic (particularly molecular-systematic) studies. It displays the name as given in the published work, the synonym and the currently accepted name and classification above genus level.

The database consists of two parts:

  • a searchable database
  • a statistic section

The searchable database allows querying (by synonym or accepted names) and display of cytological information by genus or species. There are two options for the display of search results:

  • Short output [synonymy, short reference, chromosome count]
  • Full output [classification, synonymy, full reference, chromosome count, methods, voucher specimen details]

The statistic section allows the display of diverse database characteristics:

  • Summary of all counts by year (provides a line chart overview of the counts by publication date)
    Coverage, by genus, subtribe, tribe or subfamily (the output is by default a scatter chart).
  • This section also provides an estimate of the proportional coverage within a genus or above, with an option of a tabulated summary of counts broken down by haploid chromosome number (n) by clicking the box.
