We show that the algebraic dimension of a twistor space overcannot be two ifand the fundamental system (that is, the linear system associated to the half‐anti‐canonical bundle, which is available on any twistor space) is a pencil. This means that if the algebraic dimension of a twistor space on,, is two, then the fundamental system is either empty or consists of a single member. The existence problem for a twistor space onwith algebraic dimension two is open for.
