Danish botanist, mycologist, zoologist and marine biologist
Anders Sandøe Ørsted , also written as Anders Sandoe Oersted or Anders Sandö Örsted (21 June 1816 – 3 September 1872) was a
Danish
botanist ,
mycologist ,
zoologist and
marine biologist . He was the nephew of physicist
Hans Christian Ørsted and of politician
Anders Sandøe Ørsted .
[1]
Career
In his early career, he published on Danish and
Arctic
nematodes
[2]
[3] and on the zonation of
marine algae in
Øresund .
[4]
Between 1845 and 1848, he travelled extensively in
Central America and the
Caribbean and published numerous papers on the
flora , concentrating on the plant families
Acanthaceae and
Fagaceae .

[8]
[9] One of his better known publications is
L'Amérique Centrale .
[10]
He was appointed professor of botany at the
University of Copenhagen in 1851, a post he held until 1862. He was succeeded by
Ferdinand Didrichsen .
His studies of what has since been known as
juniper-pear rust showed that this fungus annually switches between two hosts;
Juniperus sabina is the primary (
telial ) host and pear,
Pyrus communis , is the secondary (
aecial ) host. He thus was the first to discover that some
plant-parasitic fungi are
heteroecious .
[11] These studies were continued on other
Gymnosporangium species.
[12]
The
orchid genus
Oerstedella
Reichenbach f. is named for him.
He is the author of several hundred plant names still in use.
