foliage ; D. quadr'ilatera 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 pidcheUa, both varying with smooth and hispid 

 foliage ; the greater part of the species are peculiar to the 

 Colony. A, diptera^'^ is a singular slender leafless plant, with 

 the branchlets two- winged, glaucous, and bordered with a 

 strong edge; A. squamata"^ has the tips of the phyllodia 

 carved like a bird's head, and its flowers appear to be 

 brown; A. extensa^* is a graceful plant, with racemes 6-9 

 inches long, composed of alternate capitules, and slender 

 angular falcate phyllodia ; finally, A. auro?iitens'^'' 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,^^ and 

 two of Lahichea,^^ both of which are peculiar to the Colony.
