 Rh foliage; D. quadrilatera has leaves which look more like objects prepared to puzzle a geometrician than any thing already known in the vegetable kingdom.

Of Acacia numerous species occur, among which are A. alata and pulchella, both varying with smooth and hispid foliage; the greater part of the species are peculiar to the Colony. A. diptera 62 is a singular slender leafless plant, with the branchlets two-winged, glaucous, and bordered with a strong edge; A. squamata 63 has the tips of the phyllodia curved like a bird's head, and its flowers appear to be brown; A. extensa 64 is a graceful plant, with racemes 6–9 inches long, composed of alternate capitules, and slender angular falcate phyllodia; finally, A. auronitens 65 is a most beautiful stiff spiny bush, with flowers of the deepest yellow; like others it varies from being quite smooth to being covered with rough hairs.

There is one species of the beautiful genus Lalage, 68 and two of Labichea, 69 both of which are peculiar to the Colony.
