To the right is a tree with pinkish brown bark, the Brush Bloodwood Baloghia inophylla.  An interesting feature of the Brush Bloodwood is that it expels its seeds from its hard and woody seed capsules with considerable velocity.


Opposite is a very large Coastal Banksia and you may see some of the woody seed cones on the track.  Coastal Banksias can be distinguished from other Banksias by the leaves which have smooth margins and are much paler (silver-white) on the underside


Around the Banksia are numerous saplings of Plum Pine  Podocarpus elatus which has very narrow glossy green leaves 3 to 25 cm long.  The Plum Pine has easy to distinguish fruit, seen in the autumn months, which unusually is in two parts - a hard, dark inedible seed about 1 cm across, and a larger, fleshy, purple-black, seedless, grape-like edible ‘fruit’ which is actually a modified stalk.  

Plum Pine is the only gymnosperm, or non-flowering tree, found in littoral rainforests of the Manning but they do not have cones like the other conifers. An interesting feature of Plum Pine is that it is wind-pollinated with pollen grains shaped for dispersal in air currents Huge amounts of pollen are produced so that even if only a minute fraction results in reaching the target, fertilization is assured.



As you continue, you will see lots of young saplings and large woody vines (lianes) to the left of the track, reaching up to the sunlight above the canopy.
