The palmiste marron is monoecious, bearing both male and female flowers on the same plant (2) (3) (4) (8). The yellow flowers are unisexual (each flower possessing either male or female reproductive organs) and arranged in clusters, around 90 centimetres wide, that emerge from long, upward-pointing, horn-like bracts on the upper part of the trunk (2) (3). The flowers are said to have a sweet, delicate fragrance (6). The fruit of the palmiste marron is a rounded drupe, 2.5 centimetres wide, and is black when ripe (2) (3) (5).
