Abstract: Lymphoepithelium was observed in palatine and pharyngeal tonsils in possums from 2 months of age, but was not seen in the lung. Morphological maturity of lymphoid tissue occurred at about 4 months of age, coinciding with first emergence of young from the pouch. Peribronchiolar and/or perivascular lymphoid aggregations were first observed in the lung of a 3.5-month-old possum, and subpleural lymphoid aggregations were first seen at 7 months of age.
