A synonym of Biotite
The designation "Biotite-Phlogopite Series" is now out of use.
According to the new nomenclature of the Mica group (Rieder et al. 1998) "biotite" is now redefined as a series name and is not longer a valid species. The redefined biotite series comprises trioctahedral micas with compositions between, or close to, the phlogopite-annite and eastonite-siderophyllite joins.
In earlier pre-1998 litterature "biotite" has been used as name for the the end-member of the solid solution series biotite-phlogopite. With a new understanding and definition of the micas, this term is now not longer in use.
