Type specimens online: What is available, what is not, and how to proceed; Reflections based on an analysis of the images of type specimens of southern African Polygala (Polygalaceae) accessible on the worldwide web

Abstract

The results of a gap analysis of the availability of internet-hosted images of the types of names of Polygala L. (Polygalaceae) in southern Africa accessible at JSTOR Global Plants (JGP) and on other sites in the worldwide web, are presented. The type information for names associated with this genus was recorded and analyzed with a view to suggest ways in which JGP and other internet resources that host specimen images might further expand and enrich their e-holdings, and to identify which non-partner institutions should be approached to collaborate in the Global Plants Initiative (GPI), the most successful specimen imaging thrust ever. Our analysis shows that images of 52% of the types of southern African Polygala names (208 names assessed) are accessible at JGP. Of these images, 74% have incorrect metadata or no information on what sort of type it depicts. For 25% of the accepted taxa of Polygala, no images of the types of their names are available online. This gap can mostly be filled by GPI partners who hold the majority of the types not yet imaged, most of which are likely not in type folders or do not carry annotations indicating their type status. JGP would significantly benefit from directly contracting taxonomic services to improve the quality of its data on types, thus enabling information to be fed back to partner institutions.

An integrative and dynamic approach for monographing species-rich plant groups – Building the global synthesis of the angiosperm order Caryophyllales

“…Global Plants is therefore a source that facilitates taxonomic work but not yet a ready-to-use taxonomic product. the cited gap analysesThis confirmesd the results of Smith and Figueiredo (2013) on the African species of Polygala, which clearly showed that the quality of the textual data (e.g. the category of types, collector information, etc.)…”

State of our knowledge of online resources of the types of names of Agave L. (Agavaceae / Asparagaceae) with a list of names attributed to William Trelease, with notes on types, online resources and etymology

“…As part of efforts to improve the spread of names for which images, as well as associated metadata are held in JSTOR Global Plants (JGP), we conducted an analysis of the availability of images online for the types of the names of the genus Polygala Linnaeus (1753) in southern Africa (Smith & Figueiredo 2013). The species of Polygala are mostly small herbs from which herbarium specimens are easily prepared and imaged.…”
