How are Pandanus flowers arranged and why are individual flowers difficult to identify?

In the plant order Pandanales, specifically within the genus Pandanus, the flowers are simple and lack petals. They are typically arranged in dense clusters. Because these flowers are unisexual—with male and female flowers produced on different plants—they are often grouped together in tight, crowded inflorescences.12

Individual flowers are difficult to identify because they are densely packed together, and they lack a perianth (the collective term for sepals and petals) at maturity. This extreme crowding of reproductive parts, such as stamens or pistils, makes it challenging to distinguish the boundaries of a single flower within the cluster.21
