NRM holds the invaluable collection of Charophyte fructifications from both living and fossil species, including holotypes of taxa published by H. Horn af Rantzien (1959). Collections from high latitudes held at the Department of Cryptogamic Botany will provide reference material to characterise Charophyte fructifications from Nordic regions.
I´m very happy about access to the NRM facilities because, given the size of the objects, Charophyte gyrogonites need SEM-photographs to be shown correctly. Further, the project aims at studying structural details (magnification about x 3000) that can not be seen without SEM.
