In this paper, result of studies conducted in Piracicaba, São Paulo, Brazil, the authors made observations about the position of the buds at the base of the leaf sheaths to which they are associated. They used the banana plant variety Musa (AAA Group, Cavendish Sub-Group) "Nanicão", classified according to SIMMONDS' nomenclature (1966). The following conclusions were drawn :(1) The buds at the base of the leaf sheaths are found on the left, at lateral position on the sheaths. (2) The right side of the sheaths covers the younger buds which are placed more internally on the banana stem. (3) The position of the buds in the banana stem is a function of the phyllotaxy of the plant.
