Some trees in the heart of the forest grow to 10–11 m, but most are just 6–8 m high. The understory is largely absent here, formed only by scattered "Celtis paniculata", "Ficus opposita" and "Pipturus argenteus" with a height of 2–4 m; some "Celtis" also grow higher and emerge through the "Pisonia" canopy. Patches of shrubs – mainly "Abutilon albescens", with "Melanthera biflora" (probably var. "canescens"), and the introduced wild poinsettia ("Euphorbia cyathophora") – are found here and there. Herbaceous plants are scarce here, mainly consisting of the grass "Stenotaphrum micranthum". The more open forest is composed of much the same plants, but the "Pisonia" does not predominate as much. A few "Pandanus tectorius" screwpines are also found here, and the understory is far more prominent.
