Fractional

As applied to tracts of land, particularly townships, sections, quarter sections, and other divisions according to the government survey, and also mining claims, this term means that the exterior boundary lines are laid down to include the whole of such a division or such a claim, but that the tract in question does not measure up to the full extent or include the whole acreage, because a portion of it is cut off by an overlapping survey, a river or lake or some other external interference.
