was seen, and interspersed were plants of milkmaids and cockatoo 
orchid ( Glossodia major)] tiny plants such as Hydrocotyle 
c attic ar pa and trigger plant ( Stylidium sp.) grow together in 
damp situations. A form of the prickly guinea flower, with 
dark green foliage, is also seen here. 
B. Trail No. 3, Easterly 
This trail takes an easterly direction again but, being further 
away from the north ridge, it encounters undulating ground. 
The trees are blue gum and peppermint mostly, with red gum 
in the lower parts; the golden wattle is also in evidence, and 
occasional plants of the Christmas bush. Our native flax 
( Linum marginal e ) is observed with its sky-blue flowers, the 
petals of which fall very early. Kangaroo grass and century 
are seen, but they are not so numerous as the guinea flowers, 
which are very much at home in this location. On a slope away 
from a little creek there is a sheoak ( Casnarina stricta) about 
twenty feet in height. Then other plants occur, such as 
Convolvulus crubescens, a native and not a pest; Acrotriche 
serrulata ; Christmas bush; hops ( Dodonaea viscosa ) ; cranberry, 
and a mistletoe ( Loranthus Miquelii ) on the blue gum. This 
parasite appears to infest the blue gums very largely, and rarely 
other species, yet the trees are not much affected by it. 
Towards the tunnel hill the guinea flowers are much more 
numerous along a ridge where the blue gum and peppermint are 
to be seen. Associated with these trees are the following: Fringe 
myrtle ; a mat-forming pea flower ( Pultenaea pedunculata ) ; a 
spreading Hakea (H. rugosa) ; a grass with bent awns 
( Agropyrum scabrum) ; a wattle ( Acacia obliqua) : a small wall- 
flower ( Pultenaea largiflorens) ; the golden wattle, and the 
cranberry. 
On this route several orchids are to be found in the spring, 
such as the sweet-scented sun orchid (Thelymitra aristata) , a 
white variety of which was also seen, the cockatoo ( Glossodia 
major) and two spiders ( Caladenia dilatata and C. leptochila) ; 
blacks’ comb ( Isopogon ceratophyllusj ; a white everlasting 
(Helichrysum Baxteri) and the honeysuckle (Banksia mar- 
ginata) . On the last ridge before reaching the second range, 
tae:e was an abundance of teatree ( Leptosperrnum myrsinoides ) , 
Hakea rugosa, grass tree (Xanthorrkoea semi plana) , a spreading 
rush ( Lepidosperma semiteres), and less of the fringe myrtle 
and all over-topped by the blue gum. 
Over this area and in many other parts of the park, St. 
John’s Wort ( Hypericum perforatum) has become a very 
serious pest. Tt has two methods of spreading, by seed and by
