Among the botanical productions of this island there is no plant of so striking a feature as the callitris, a tree of about twenty-five feet high, with a short stem of three feet in diameter; it much resembles the Pinus cedrus, or cedar of Lebanon, in its robust horizontal growth; it is found abundantly over the island, and within a few yards of the sea-beach.

The island is formed by a succession of small hills and intervening valleys; and although the soil is very poor, being principally a mixture of quartzose sand and a large proportion of marine exuviae, yet this tree grows to a considerable size, but covering the surface of the island, gives it a monotonous appearance which is however occasionally relieved by a spreading undescribed species of melaleuca (allied to Melaleuca armillaris, Smith) and the more elegant pittosporum, an arborescent species, also undescribed.

In fact, these three trees constitute the timber of the island.

The ground is in some parts profusely clothed with Spinifex hirsutus, Labil., in which I detected a new species of xerotes, a round bushy plant growing in large bodies.
"No fresh water has ever been discovered upon this island: indeed the loose filtering nature of the soil is not tenacious enough to retain that element at the surface.

The woods are abundantly stocked with a small species of kangaroo of which we saw only the traces; nor did we see the animal, on account of whose numbers and resemblance to a rat the island received its name from Vlaming in 1619.
