# Gustaf Lagerheim

Nils Gustaf Lagerheim (1860–1926) was a Swedish botanist, mycologist, phycologist, and pteridologist.

Today, he is best remembered as one of the chief architects of pollen analysis as a tool in botany, alongside his student Ernst Post.

In 1895, botanists Giovanni Battista De Toni and Robert Hippolyte Chodat published Lagerheimia, which is a genus of green algae in the family Oocystaceae, named in his honour. Then in 1940, Boedijn published Lagerheimiella, another green algae genus.

The standard author abbreviation Lagerh. is used to indicate this person as the author when citing a botanical name.
