from Wikipedia, the free encyclopedia

Ivar Frederick Tidestrøm (born November 13, 1864 in Hidinge , Närke province in Sweden , † August 2, 1956 in Saint Petersburg , Florida ) was a Swedish botanist . Its botanical author's abbreviation is " Tidestr. " His specialties were the seed plants (Spermatophytina) and the fern-like plants (Pteridophyta) .

life and career

Tidestrøm attended school in Örebro . In 1880 he went to New York , where he joined the 4th Cavalry of the US Army that same year . In 1884 he injured his hip in a fall from his horse and temporarily retired, but served again in the US Army from 1887 to 1891. In 1891 he began to study engineering at the University of California . There he became an assistant to Edward Lee Greene and switched to biology. When Greene accepted a professorship at Catholic University in Washington, DC , he followed him and earned a Ph.D. in 1897. In 1903 he became botanical assistant at the Bureau of Plant Industry under the botanist Frederick V. Coville for $ 40 a month .

His first major publication, Elysium Marianum (1906-10), was an illustrated work on the flora of Maryland . In 1910, Professor Greene was in charge of botany at the Smithsonian , working on behalf of the Forest Service to identify a large collection of plants. Shortly before Greene's death in 1915, Tidestrøm took over the identification and collection work and worked on a key to identify the flora of the western states. He published his work, Flora of Utah and Nevada, based on it, in 1925.

When he retired from the US Department of Agriculture in 1924 , he was one of the greatest capacities for flora in the United States. He returned to Catholic University and took over the botanical department for five years. He retired in Florida in 1931 at the age of 75. His later, larger work Flora of Arizona and New Mexico (1941) he wrote together with his sister Mary Teresita Kittell. On his last trip, which took the 90-year-old to a family reunion in Sweden in 1954, he added 300 new ones to the 14,000 collections at the Smithsonian Institute .

Honors

The generic name Tidestromia Standl. from the family of the ( Amaranthaceae ) and some kind epithets like Penstemon tidestromii Pennell and Viola tidestromii Greene are reminiscent of him.

He was accepted into the Washington Biologists' Field Club in 1910 and ended his membership in 1946 for personal reasons.
