occur shrubs of Dodonaea viscosa , many of them galled, and 
occasional examples of the olive, Asclepias, Olearia ramulosa, 
and the pea Psoralea patens. Undershrubs and herbaceous plants 
include the grass Poa caespitosa , carrot fern, Lomandra fli- 
formis, Dianella, the amaryllid Calostemma purpureum, Geranium 
pilosum, Halorrhagis, Convolvulus erubescens , Galium , Scaevola, 
and various annuals. The grass-tree, commonly often called 
“yacca” ( Xanthorrhoea quadrangulata ) , Logania vaginalis , and 
the Dodonaea can be seen scattered on the steep slope above the 
water of the reservoir. Following the same hill-slope in an 
easterly direction so as to be on the south of the creek between 
the first and second waterfalls, we find the addition of such other 
species as Banksia (galled), Solanum aviculare, Bursaria, the 
carrot fern, the Australian bluebell ( Wahlenbergia vinciflora ), 
Senecio hypoleucus, and more of the Logania and grass-tree. In 
the upper parts E. leucoxylon and E. viminalis again replace the 
sheoaks. As the hill sweeps round in an easterly direction, pre- 
senting a view straight down the gorge towards Adelaide, the 
stringybark (E. obliqua ) association comes in on the quartzite, 
and still further round, just at the edge of the reserve, the 
mallee-like Eucalyptus cosmophylla presents a feature of its own. 
Amongst the rough stones near the bottom of the quartzite slope, 
just above the second waterfall, the underscrub is thick, consist- 
ing of Hakea rostrata, H. ulicina, Eucalyptus cosmophylla , 
Dodonaea viscosa, Olearia ramulosa, Calythrix tetragona, 
Casuarina Mitelleriana , Acacia myrtifolia, Pultenaea daphnoides, 
Solanum aviculare, Clematis, bracken, the sedge Lepidosperma 
laterale, and an occasional Exocarpus cupressiformis with scat- 
tered E. obliqua. More lowly plants are Hibbertia sericea, 
Dianella, Astroloma humifusum, Epacris impr'essa, Acrotriche 
fasciculi flora and A. serrulata, Ixodia achilleoides, and 
Lomandra dura. The underscrub gets less as one ascends and 
the stringybarks more numerous. Here Hibbertia acicularis var. 
sessiliflora, Leptospermum myrsinoides, and Pimelea may be met 
with. Near the Mount Barker road on top, Xanthorrhoea semi- 
plana comes in, and there are a few golden wattles and sheoaks 
where the stringybarks mix with the manna and blue gums. 
The slope on the northern side of the creek is very steep 
with much scree. On the westerly end, some bold rocks project 
and sheoaks are prominent. These pass into scattered stringy- 
barks and underscrub on the easterly portion. 
Some swampy, peaty soil abuts on both sides of the second 
waterfall. Here flourish the cutting grass (a sedge, Galmia 
psittacorum) , species of Car ex and Scirpus, rushes such as J uncus 
pallidus, J. pauciflorus and others, bracken, the coral fern and
