This paper reviews experimental results concerning magnetic anisotropy in geometrically frustrated kagome staircase lattices. Following problems are discussed: high-temperature susceptibility measurements of kagome single crystals; inelastic neutron scattering measurements on Co(3)V(2)O(8) single crystals; EPR of Co(2 ) ions in kagome staircase Mg(3)V(2)O(8) single crystals. The single-ion anisotropy Hamiltonian is used to analyze experimental results. It is suggested that the magnetic anisotropy in kagome staircase M(3)V(2)O(8) (M = Co, Ni, Mn) oxides has mainly single-ion origin.
