A shrouded rotor blade annulus for a double flow centripetal turbine stage, comprising a center row of radial blades and two end rows of axial blades mounted on the periphery of a turbine rotor disc or drum, and two segmented annular shrouds, each covering the top of an axial blade row and one side of the radial blade row, with the shroud segments being integral with the axial blades. In an alternate embodiment, the radial blades are integral with shroud segments forming the side portion of the two shrouds adjacent these radial blades and the axial blades are integral with adjacent shroud segments forming the deck portion of these shrouds and covering the axial blade rows.
