ABSTRACT. Sphagnum heinrichsii is the second specimen of this genus from Eocene amber of Europe, and is preserved with more detail than the first unnamed Sphagnum from Baltic amber, which was referred to the sect. Acutifolia. Sphagnum heinrichsii is represented by one stem fragment with about seven branches. The branch leaf pore arrangement points to a relationship with sect. Cuspidata. However stem leaf pores are rather more like those of sect. Subsecunda.
