Ultrastructure studies on four newly recorded species of Chrysochromulina (Haptophyta) in China

Members of Chrysochromulina are important components of marine phytoplankton. Four species in this genus are reported in China for the first time, namely Chrysochromulina cymbium Leadbeater & Manton, C hirta Manton, C. megacylindra Leadbeater, C. pringsheimii Parke & Manton.
