We study the generalized maple-leaf model along the axis interpolating between the isotropic ruby lattice and the isotropic maple-leaf lattice, using two independent variational infinite projected entangled-pair state ans\\\"atze: one defined on the mapped square lattice and one directly on the native triangular lattice.
