danser

Benedictus Hubertus Danser (May 24, 1891, Schiedam, Netherlands – October 18, 1943, Groningen), often abbreviated B. H. Danser, was a Dutch taxonomist and botanist. Danser specialised in the carnivorous plant genus Nepenthes. In 1928, Danser made an exhaustive revision of the genus, recognising 65 species in The Nepenthaceae of the Netherlands Indies. Today, over 100 species of Nepenthes are known, but Danser's work is still often referenced by specialists in the field. Nepenthes danseri is named after him.
