The Monograptina are a group of graptolites known from the Lower Silurian to the Lower Devonian, characterised by the production of a uniserial rhabdosome with thecae along one side only of the central stipe (Bulman 1970).

Characters (from Bulman 1970): Scandent, uniserial; development monograptid, with sinus method of pore formation and initially upward direction of growth of th1.
