and Restio complanatus. Grasses are relatively few, and 
practically restricted to Aristida aff. heterochaeta , The - 
meda australis , Eremochloa sp., Eriachne vara, Schiza- 
chyrium obliquiberbe , and Panicum fulgidum . • Other her- 
baceous plants include Drosera spp., Mitrasacme paludosa , 
and Sowerbaea juncea. 
In the wetter places there is a tendency to the forma- 
tion of the swamps described above, often with Melaleuca 
viridiflora present. This frequently occurs flowering as 
a small shrub, partly at least as the result of fire (see 
fig. 4). Sphagnum is fairly abundant in such places, like- 
wise the bungwall fern, Blechnum serrulatum. . Other 
plants usually occurring in such places are Melastoma 
malabathricum , Pultenaea paleacea var. grancliflora , Vil- 
larsia reniformis, Restio tetraphyllus, Ischaemum aus- 
trale , and i Utricularia. Gahnia erythrocarpa , usually 
common in such situations elsewhere, is here only occa- 
sionally seen. 
On the higher places the restiads tend to disappear, 
grasses become more abundant and Banhsia ser rati folia 
and B. int eg ri folia occur. In a modified form this type of 
vegetation extends up the slopes of Mt. Perigian, and on 
the eastern side of Mt. Coolum. The commonest plants 
are Xanthorrhoea minor , stunted bushes of Banhsia in- 
tegrifolia var. paludosa , Casuarina suberosa , Exocarpus 
cupressiformis, Petrophila Shirley ae , etc., with kangaroo 
grass. At the foot of the former peak occur a few trees 
of the rather dwarf, very scraggy Eucalyptus Seeana var. 
constrict a , associated with Melaleuca viridiflora and other 
plants. 
The tops of both mountains are open and without 
any continuous layer of soil. Aristida jerichoensis (a rare 
spear-grass) occurs on both peaks, while the yellow-flower- 
ed composite Rutidosis Murchisonii is particularly abund- 
ant on Mt. Coolum, though it occurs also on Mt. Perigian. 
On the rocks of the latter are to be found Dendrobium 
speciosum (king orchid), and the rambling Hoy a australis , 
"with its broad, fleshy leaves and white strongly-scented 
flowers. A solitary plant of Mesembrianthemum aequi- 
laterale (pig-face) was also seen, a most unusual habitat 
for this species. The peculiar little grass Tripogon lolii- 
formis occupies patches of soil between the rocks. The 
rock faces on Mt. Coolum are commonly occupied by the 
curious Xerotes confertifolia , with its small, dense tufts of 
narrow rigid curly leaves with two pungent points at the 
end, and its inconspicuous flowers. In the Eucalyptus 
forest near the top the rush-like sedge, Scho&nus vagi- 
natus, was observed. On the banks of a small creek near 
the foot occur the ferns, Culcita dubia (mountain
