OF NEW HOLLAND. 137 
Classes or Divisions. I am very far from anticipating that this 
arrangement of mine will hold good, when New Holland 
Shall be more fully explored, and when repeated observations 
of this nature shall enable future observers to combine such 
detached remarks into one comprehensive view, and to cor- 
rect my partial statements by reference to more extensive 
investigations. I shall therefore feel neither surprised nor 
disappointed if some of my Divisions should subsequently 
. merge into those laid down by abler pens. : 
. First crass. The Coast Vegetation from Sydney south to 
lllawarra.—lts subsoil is the almost shifting sand of the 
places contiguous to the sea coast; or rocks of coal-sand- 
. Stone, either naked or very slightly covered with earth; or it 
.. ‘May be seen occurring around those small ponds of salt or 
brackish water, which are exceedingly common in these dis- 
tricts. In such localities as these, the Epacris, Boronia, 
Dillwynia, Gompholobium, Xanthorrhea, Hakea, Grevillea, 
Persoonia, Lambertia, Astroloma, Lomatia, Comesperma, 
.. Leucopogon and Xerotes are prevalent and characteristic 
tribes, while no kind of forest-tree, except the Eucalypti, is 
Mable: Thé above-named plants grow in such dense masses, 
. that men and cattle penetrate with difficulty, presenting a 
‘Striking analogy with the plains of South Africa. "The stiff 
and dry nature of the foliage prevents their being applied to 
 *üy economic purposes. 
SECOND CLASS. Vegetation of Rocky Gullies near the Sea- 
~ Q00sl.— In these localities, a small number of springs may be 
. Seen, which feed the few creeks on the sea-coast. This 
~ Moisture, whether permanent or periodical, generates a series 
of plants, not met with elsewhere. In such gullies, and the 
. Small flats surrounded by them, appear the only two kinds of 
: ‘aims that are indigenous to Australia. Here the Corypha 
 “ustralis rears its annulated stem to a height of a hundred 
feet, and the Seaforthia attains an equal stature, but with a 
E thicker and smoother trunk. The Arborescent Fern (Also- 
~ Phila) likewise affects these spots ; also that splendid ornament
