Would you like a response? Your name. The southern portion of the Plateau is largely State Forest. The underlying rock is Narrabeen sandstone, which has been eroded by the Wolgan River in the west and other streams, leaving rugged ridges with rocky outcrops and deep gullies.
The soil is generally poor and the weather harsh, with cold winters and hot summers. These conditions, where only the toughest plants can survive, have encouraged a flora with greater species diversity than in areas with more favourable circumstances.
Access to Newnes Plateau is via forest roads leading north from the Zig Zag tourist railway station at Clarence. Refer topographical map "Wallerawang" or topographical maps "Lithgow" and "Cullen Bullen".
We didn't have far to go to reach our first botanising stop - only a few hundred metres. It was a flat, open forested area with a good variety of species, which had regenerated well after a fire perhaps two or three years ago. Here we found the first of the multitude of Persoonia species we were to see over the weekend. Persoonia recedens is a low spreading shrub which until recently was known as a subspecies of P.
Its habitat is restricted to the upper Blue Mountains, as is that of P. Bordering the road were vibrant light-green carpets of P. Phil identified another Persoonia here as closely resembling P.
Boronia microphylla , flowering abundantly here, gave a softly colourful backdrop to the understorey. Its range of colours was from red to pale pink and even pure white. Phil explained that the white form of flower may be produced if only one enzyme is lacking during the chain of chemical reactions required for the plant to grow. This led to a discussion on the reasons for inaccurate colours of flowers in photography. Sometimes a photo of a blue Dampiera comes out almost pink.
This is because the eye and the film collect different wavelengths of light. The heath form of Hakea dactyloides , with bronze-coloured new growth, was common here. Phil mentioned that this form with lignotuber was so different to the forest form that it should probably be given separate species status. Proceeding down the road just past the sandmining operation, we admired an attractive stand of the inland form of Astrotricha longifolia in full bloom. These plants could take their place in any garden!
Phil also pointed out an unusual form of Lomandra longifolia , with short leaves and flower stems and quite a sparse habit. The next stop was Murray's Swamp.
We came here to see several rare plants - the first, Boronia deanei , was flowering in a number of locations in and around the swamp. The second was Grevillea x gaudichaudii - the natural hybrid which was once thought to be a species. Here it was growing midway between its parents - G. It was easy to see why both G. A third rare plant we observed was Isopogon prostratus , its matted foliage hugging the ground amongst the pines.
Growing in the swamp with its blue-violet racemes was Derwentia blakelyi. This plant, until recently classified as a Parahebe , also has a restricted distribution.
