Making use of the Ginzburg-Landau free energy, singularities such as disgyrations and vortex lines and stable textures in the planar (or twodimensional) texture are studied. Here both f and a vectors, characterizing the texture in 3He-A, are assumed parallel to each other and lie always in a plane.

We calculate the equilibrium configurations of three textures in a narrow cylinder in the presence of superflow along the cylinder axis. The Mermin-Ho texture is shown to be unstable against a small twist in the dipole-free limit even in the absence of superflow. The radial disgyration undergoes a s
