PLANTS INDIGENOUS TO NORTH-WEST OF VICTORIA, 463 
found here and there in sandy, springy soils. This plant is con- 
sidered to be poisonous, as neither sheep nor cattle will touch it, 
although it remains green when everything else is burnt up. 
Limosella Curdieana is an aquatic, found in most permanent 
waterholes. The number of Epacridaceous plants inhabiting the 
scrub country is also large, but the only one which may be 
regarded as entirely confined to this region is Styphelia cordi- 
Solia, a tall growing species, with small flowers, and cordate leaves, 
of very rare occurrence. S, Sonderi is found widely diffused. 
The conifers are represented by Callitris verrucosa and O. cupres- 
siformis, both of frequent occurrence. The grasses confined to 
this region are not very many, the most noticeable being Panicum 
decompositum, Newrachne alopecuroides, Aristida Behriana, Stipa 
elegantissima, Stipa aristiglumis, Poa ramigera in swampy places, 
Diplachne fusca, Triodia irritans and Triraphis mollis. The order 
Orchidew is also well represented, but only by species extending 
to other parts of the colony. 
The plants which are to be found on and around Mount 
Arapiles, but extending no further west, are for the most part 
identical with those found in similar situations in the Grampian 
Mountains. A few are, however, not existing to the writer’s 
knowledge, anywhere else, but at Mount Arapiles. In the 
rockiest and most inaccessible gullies, may be found the mal- 
vaceous plant, Howittia trilocularis ; a tall shrub, bearing purple 
blossoms. On the summit of the mountain grow large bushes of 
the showy Eriostemon obovalis, and in the scrub around the base 
are a few scattered bushes of Prostanthera spinosa, a thorny 
species of low growth bearing large white flowers dotted with 
purple in the throat. At the base grow also large clumps of 
Acacia rupicola, a species which when bruised emit a pleasant 
scent. Phyllanthus Gunnii occurs sparsely as a graceful small tree 
in the principal gully on the west side of the Mount. On paying 
a subsequent visit to the locality, it was found that the shrubs 
had disappeared, being killed by rabbits or bush fires. Large 
trees of Pittosphorum phillyreoides grow on the limestone rises 
not far from the base ot the Mount, having stems quite 18 inches 
in diameter. In the clefts of the Mitre rock grow a few bunches 
of Psilotum triquetrum, a plant found nowhere else in Victoria, 
specimens of which were first gathered by the writer and sub- 
mitted to Baron von Mueller, and compared with some which he 
gathered himself in the Port Jackson district many years ago. 
A variety of Correa speciosa of tall growth with whitish flowers 
bearing some resemblance to O. Lawrenciana of the Grampians 
occurs in all the gorges, and in the crannies of the rocks grow a 
large variety of Alternanthera triandra. LEpacris impressa is 
represented by a variety with larger and deeper coloured 
flowers than those of the sort prevalent in the Little Desert
