Ivar Tidestrom

Tidestrom was born on his father's estate "Lanna" in Hidinge parish in Närke, near modern Vintrosa, the third of five children of Constantin Tideström (1830-1893) and his wife Brita Ulrika Wallmo (1835-1921).

By 1903 Tidestrom was out of the military and had a job at the Bureau of Plant Industry under botanist Frederick Vernon Coville.

With his student Sister Mary Teresita Kittell he published Flora of Arizona and New Mexico in 1941.

He was an accomplished linguist who spoke Swedish, English, French, Spanish, and German, could read Latin, Danish, and Norwegian, and studied other languages as well.

The genus Tidestromia of desert and arid environment plants was named after Tidestrom by Paul Carpenter Standley.
