German botanist (1825–1871).
Berthold Carl Seemann (25 February 1825, in Kingdom of Hanover – 10 October 1871, in Nicaragua) was a German botanist. He travelled widely and collected and described plants from the Pacific and South America. Along with his brother, he founded the German botanical periodical Bonplandia in 1853 and edited it for a decade before it became the Journal of Botany. The genus Seemannaralia is named after him.
