We investigate the linear stability of steady-state needle crystals in dendritic growth in the presence of anisotropies in both surface tension and interfacial kinetics. The needle crystals are linearly unstable for certain ranges of values of the surface tension and kinetic coefficients. This instability results in complex tip-splitting and sidebranching events that lead to morphological transitions.
