Hoek, Mann and Jahns system

The Hoek, Mann and Jahns system is a system of taxonomy of algae. It was first published in Algae: An Introduction to Phycology by Cambridge University Press in 1995.

Division Cryptophyta

Division Dinophyta

Division Euglenophyta

  • Order Euglenales (e.g., Euglena, Astasia)
  • Order Eutreptiales
  • Order Euglenamorphales
  • Order Rhabdomonadales
  • Order Sphenomonadales
  • Order Heteronematales

Division Chlorarachniophyta

Division Chlorophyta

  • Class Cladophorophyceae
  • Class Dasycladophyceae
  • Class Trentepohliophyceae
  • Position uncertain:

Note added in proof

In a note added in proof, an alternative classification is presented for the class Chlorophyceae:

  • Class Chlamydophyceae
  • Class Oedogoniophyceae

Many examples of genus given in the book could not be assigned to one of these classes, because the ultrastructural characteristics needed for their classification have not yet been studied.
