Abstract: In this study SEM and light microscopy were used to investigate the structure of the foliate papillae in the porcupine. The foliate papillae consisted of about 10 or 11 clefts. The length of the foliate papillae averaged 2.79 mm and its width averaged 863 µm. Taste buds were located intraepithelial in the basal half of the papilla grooves (sulcus papillae). Every wall on each fold harboured from five to nine taste buds. There were two different cell types of taste buds: one stained light (epitheliocytus sensorius gustatorius), and the other dark (epitheliocytus sustentans). The length and width of the taste buds averaged 190.5 µm and 86 µm, respectively. The ratio of the length to the width of taste buds was 2.21. The average depth of the papilla groves was 1763 µm and its epithelial thickness was 235.5 µm. In scanning electron microscopy, the thickness of the epithelial cell borders was apparent at higher magnifications and there micro-ridges and micro-pits were apparent on the surfaces of these cells.
