A condition of buffaloes characterized by an increased volume of one of the cheeks was shown to be due to accumulation of the seeds of the palm-tree "mucaja" (Acrocomia aculeata) and of grass, in the oral vestibulum during rumination. This caused compressive atrophy with thinning and medial deviation of the corresponding submaxillary bone and exposition of the roots of molar teeth. The seeds appear to be of good palatability to the buffaloes.
