The marine diatom genus rhizosolenia : A new approach to the taxonomy
The silica wall in 35 species of the marine planktonic diatom genus Rhizosolenia Brightwell has been examined with light and electron microscopy. The genus Rhizosolenia is revised and an emended circumscription comprising 24 species is proposed. Five new species (Rh. acicularis, Rh. borealis, Rh. ostenfeldii, Rh. fallax, Rh. decipiens) and four new infraspecific taxa (Rh. polydactyla f.squamosa, R
