Impact of cultivation and gathering of medicinal plants on biodiversity: global trends and issues. (2003, background): “5 World 422 000 52 885 Sources: Duke and Ayensu (1985); Govaerts (2001); Groombridge and Jenkins (1994, 2002); Jain and DeFillipps (1991); Moerman (1996); Padua et al.”
Why are there so many plant species in the Neotropics (2011, background): “This is perhaps more than tropical Africa (30,000–35,000 spp.) and tropical Asia and Oceania combined (40,000–82,000 spp.; Gentry, 1982; Thomas, 1999; Govaerts, 2001).”
Plant Species Identification Using Computer Vision Techniques: A Systematic Literature Review (2017, background): “Given that the worldwide estimates of flowering plant species (aka angiosperms) vary between 220,000 [90, 125] and 420,000 [52], we would like to know how many species were considered in studies to gain an understanding of the generalizability of results.”
Plant species identification using digital morphometrics: A review (2012, background): “Estimates of numbers of species of flowering plants (or angiosperms) vary from about 220,000 (Scotland & Wortley, 2003) to 420,000 (Govaerts, 2001).”
Innovative approaches to the preservation of forest trees (2014, neutral): “With an estimated 223,000–353,000 species of higher plants (Scotland and Wortley, 2003; Chapman, 2009) and the physiological screening of all species unlikely in the short- to medium-term, it is important to develop predictive biological models that help indicate risks associated with handling seeds”
Biodiversity inventory and informatics in Southeast Asia (2010, background): “…ca. 50% in Croton of Madagascar, B. van Ee, pers. comm.), and in pre-revision checklists of diverse regions, although synonymy rates can be very high in unrevised groups (e.g., 4,861 synonym names for 1,006 species in F. Slik’s Southeast Asia tree checklist;1 see also Scotland and Wortley 2003).”
Medicinal plants, conservation and livelihoods (2004, background): “species of vascular plants are already known, with a further 10–20% to be discovered (Govaerts 2001).”
Coverage Provided by the Global Protected-Area System: Is It Enough? (2004, background): “This task is enormous, since the estimated number of described vascular species (i.e., all flowering plants, plus ferns and fern allies) varies from 270,000 December 2004 / Vol. 54 No. 12 • BioScience 1087 1088 BioScience • December 2004 / Vol. 54 No. 12 (Thorne 2002) to 422,000 (Govaerts 2001).”
Illustrated Pollen Terminology (2018, background): “From ca. 260.000 to 422.000 plant species (e.g., Thorne 2002; Govaerts 2003; Scotland and Wortley 2003; The Plant List currently accepts 350.699 species) only about 10% have been studied with respect to pollen grain morphology, and regarding pollen ultrastructure it is even much less.”
