1. Coastal Plain slio^ving tlie sharp junction ‘with the 
Cadgibiit ISiirubland, A'aigi. 
(I>) Loam Flats. 
(i) The grass plains are relati\ely uiiiin])ortant until the Anna Plains 
couiitvy is i‘eaeh(Hl. Flsewhere only odd patches occur between the sandhills. 
Also over a good deal of the area the native grasses have been replaced by 
the introduc(‘(l speci(‘s Ceyiclirun clJiaris (Huffel (trass). i\Iost of the indcs 
concerning tin* native grass(‘s wcu'e ma<le at Anna Plains Avhere the Mats have 
])een grazed by catth* for some y(‘ars. Whether there has been any Moristic 
alteration as a I’esnlt of the grazing it is not ))ossib](‘ to say on tin' availabh' 
information. 
Triodia inmytns is lacking from tin' loam soils. Tlu' grassland is a 
mi.xture of species and it would be ditlicult to say which is the most important. 
Species which do occur are h'ragrosfis Dirfsd', K. larunaria, Xerochloa harhata, 
Enneapogon phmifoUus, EporoJxjhis actinocladus, Triraphis mollis, Dicliini- 
thium humilius, Chloris rnderalis, Vanicum decompositum var. scaherriminn 
and also Sporobolus virginictt.'^ which has two growth forms. As Salt Grass 
it foi’ms a coarse mat 8-12 inches thick of erect culms whi^e as Coastal ('’o’U'h 
grass it has long trailing culms oft('ii more than twelve feet in length. The 
two forms app(*ar to be tin* i‘(*snlt of a r(‘sponse to a slight alteration in soil 
piineral salt content.
