Taxonomy term
Ursinia
{"type":"FeatureCollection","features":[]}
Named in honour of Johann Ursinus of Regensburg, the author of Arboretum Biblicum. Sphenogyne R.Br. is not considered separable.
Veltheimia
{"type":"FeatureCollection","features":[]}
For August Ferdinand von Veltheim (1741–1801), German mineralogist, with interests in geology, archaeology, and civic matters related to his estates. He was inspector of the mines in the mining district of the Hartz Mountains (1766) but declined an offer as general inspector of mines and salt works in Russia’s western regions. Among other books he authored a geology book, Etwas über die Bildung des Basalts (1787), the first person to correctly attribute the origins of granite to volcanic action. He developed and beautified a botanical garden on the grounds of Castle Uarbke at Harbke, and was a patron of botany. He received an honorary PhD from the University of Helmstedt, was elected an honorary member of the Prussian Academy of Arts, and appointed a count by the king of Prussia.
Vlokia
{"type":"FeatureCollection","features":[]}
For Johannes Hendrik Jacobus Vlok (1957– ), South African nature conservationist. He has a diploma in forestry (1982) and an MSc (cum laude) from the University of Natal (1997). He was a research forester at Saasveld (1982–1900), nature conservation officer (1990–1997), and since 1998 has acted in a consultant or advisory capacity to the World Wildlife Federation South Africa, Cape Nature, South African National Parks, and national, provincial and private institutions in the fields of land conservation, impact assessment and environmental control. He has authored more than 30 scientific and popular articles, and has made many presentations at scientific forums on ecological and floristic studies. He is the recipient of the Leslie Hill (2003) and Gold (2006) awards for his contribution to conservation.
Wahlenbergia
{"type":"FeatureCollection","features":[]}
For Georg Göran Wahlenberg (1780–1851), Swedish naturalist, geographer and doctor, who became a demonstrator in botany (1815–1828) and professor of botany at the University of Uppsala (1828–1851), succeeding Carl Peter Thunberg. Wahlenberg made his main work in the field of plant geography, and published, among other things the Flora Lapponica (1812), a considerably extended version of the work of his compatriot Linnaeus, who wrote a publication of the same name (1737). His other works were based on his trips to Norway, Finland and the plant world of northernmost Sweden. Wahlenberg was elected a member of the Royal Swedish Academy of Sciences in 1808.
Wahlenbergia sp
{"type":"FeatureCollection","features":[]}
Named in honour of Georg (Goran) Wahlenberg (1780 – 1851), a Swedish botanist, successor to Carl Thunberg, and author of A Botany of Lapland.
Whiteheadia
{"type":"FeatureCollection","features":[]}
For Henry Whitehead (1817–1884), English-Anglican missionary and plant collector. He came to South Africa in 1855 and spent a year at a mission station in Namaqualand, near Springbok. He collected in that area, also in the Clanwilliam district, sending specimens to William Henry Harvey in Dublin, who acknowledged his collection in Flora Capensis (1862). As a result of the failure of copper mines, Whitehead was transferred to Tulbagh before being sent to St Helena in 1861, where he stayed until he died. He sent collected ferns to Kew Gardens, also to Carl Wilhelm Ludwig Pappe (1803–1862) and William Rawson (1812–1899) in Cape Town, authors of Synopsis Filicum Africae Australis (1858).
Whiteheadia bifolia
{"type":"FeatureCollection","features":[]}
Latin bifolia, means "two leaves".
Wiborgia
{"type":"FeatureCollection","features":[]}
For Eric Nissen Viborg (1759–1822), Danish veterinarian and botanist. He studied under Peter Christian Abildgaard (1780), became professor of botany at the University of Copenhagen (1797–1801), and director of the botanical garden. In 1801, he became professor and rector of the Royal Veterinary and Agricultural School in Copenhagen. He wrote important works on animal medicine, horse breeding, sheep farming and the treatment of infectious diseases in pigs. His botanical publications include a paper on the use of sand plants to stabilise the coast of Jutland (1789), and he did much work on systematising Danish names for indigenous plants (1793). He was a member of the Academy of Sciences and other societies. His name was misspelled by Carl Peter Thunberg.
Zaluzianskya
{"type":"FeatureCollection","features":[]}
For Adam Zalusiansky von Zaluzian (1558–1613), Bohemian botanist and physician, lecturer and administrator at Charles University in Prague, author of Methodus Herbariae Libri Tres (1592). He was the first man to argue for the separation of botany from medicine, and for a universal classification of plants years before Linnaeus. He stated (in translation): ‘It is customary to connect medicine with botany, yet scientific treatment demands that we should consider each separately. For the fact is that in every art, theory must be disconnected and separated from practice, and the two must be dealt with singly and individually in their proper order before they are united. And for that reason, in order that botany (which is, as it were, a special branch of physics) may form a unit by itself before it can be brought into connection with other sciences, it must be divided and unyoked from medicine.’ Quotation from Herbals: Their Origin and Evolution (Agnes Arbe).
Zygophyllum
{"type":"FeatureCollection","features":[]}
Gk. zygon = a yoke; phyllum = leaf. The leaves are usually bifoliolate – the two leaflets are as if ‘yoked together’.
