But the predominant order is the Proteaceae, of which there are between sixty and seventy supposed species, many of extinct genera, but some referred to the following living forms Dryandra, Grevillea, Hakea, Banksia, Persoonia all now belonging to Australia, and Leucospermum, species of which form small bushes at the Cape.
On a RECONNOISSANCE I traversed the continuation of the range, which I found to be of a flat, sandy, and rotten character, having, with the exception of the Blackbutt, all the trees and other characteristics of the sandstone country of Moreton Bay: Xylomelum, Xanthorrhaea, Zamia, Leptospermum, a new species of forest oak, which deserves the name of Casuarina VILLOSA, for its bark looks quite villous; Persoonia falcata, R. Br., a small tree about fifteen feet high, with stiff glaucous falcate leaves, and racemose inflorescence; a dwarf Persoonia, with linear leaves, the stringy-bark, and a species of Melaleuca along the creek.
The trees, with the exception of the flooded-gum, are of stunted habit; and scrub is here developed ad infinitum. I examined the wood of all the arborescent Proteaceae which I met with, and observed in all of them, with the exception of Persoonia, the great development of the medullary rays, as it exists in several species of Casuarina.
They have been referred to the genera Banksia, Grevillea, Hakea, and Persoonia. Of Hakea there is the impression of a supposed seed- vessel, with its characteristic thick stalk and seeds, but as the fruit is without structure, and has not yet been found attached to the same stem as the leaf, the proof is incomplete.
