OF TASMANIAN PLANTS IN SOUTH AUSTRALIA. 73 
ornata, Adenanthus sp., Drosera binata, Xyris operculata were 
observed, the two latter in full bloom. At about 9 or 10 miles 
from our starting-point, we arrived at our destination, a level 
marshy flat surrounded by weird-looking hills on all sides and 
a square mile or two in extent. The locality is uninhabited, and 
known locally by the term * Square Waterhole.” About 13 mile 
S.E. rises a steep hill, its summit formed by bare white rocks, 
from which it has received the name Mount Jagged. 
After arranging our camp we began collecting, and found this 
marsh to be as fine a representation of a South-Australian moor 
as could well be imagined. Consisting of black mould spread 
over fine white sand, as exhibited by some drains, it was densely 
overgrown by Sprengelia incarnata, Leptospermum lanigerum, and 
Melaleuca squamea in dense clumps, numerous Cyperacee and 
Juncaceæ intermixed with Utricularia dichotoma in thousands; 
while Lycopodium laterale, Schizea bifida, and Lindsaya linearis 
overspread the less grassy spots. Calostrophus lateriflorus and 
Patersonia longiscapa were very abundant in the very moist 
spots. Patersonia glauca, on the contrary, occupied drier spots 
along the margin. We were surprised to find many plants in 
full bloom, while at this late date scarcely any could be found in 
drier places, or had long passed it there. 
Owing to the exceptionally dry season the marsh was dry 
enough to allow us to cross it with care, after we had examined 
part of its S.W. edge, where we found several strong springs. 
Following a drain, &e., we succeeded without much ill adventure 
in getting to theoutlet on the N.E. side. What rather surprised 
us was, that at several places all appearance of water vanished, and 
some 100 yards further on the murmuring of a strong stream 
among dense bushes became audible; this occurred repeatedly, 
even in the narrow bed of the gully, through which the waters 
escaped towards the N.E. The lower hills surrounding the 
marsh consisted of Tertiary gravels and clays, the former exhibit- 
ing numerous symmetrically rounded and polished pebbles of 
older rocks in all sizes, but no fossils. 
Next day the hills to the south and Mount Jagged were ex- 
amined ; the latter was found by Prof. Tate to be about 1465 feet 
high, the edge of the Miocene about 2200 feet and that of the 
flat itself about 880 feet above the sea. The summit of Mount 
d consists of snow-white fine-grained quartzite of pre-Silu- 
the angle of dip being about or near 90°, with a strike
