slopes, ca. 2,600 feet, October 8tli, 1944, Blake 15424 (stems 
very oblique, often forming tangled masses, up to 12 feet 
or more, green; spikelets dull grey or dull brown) and 
Blake 15425 (small starved specimens from a dry bank). 
Previously known from New South Wales, Victoria 
and South Australia. On parts of the McPherson Range, 
particularly near the source of Nixon’s Creek, near 
Surprise Rock, and on parts of the eastern side of the 
Coomera Gorge, this plant forms large tangled masses of 
tough rush-like stems on ground where the water-table is 
forced close to the surface due often to a stratum of 
obsidian. It is commonly associated with Schoenus mela fl- 
oat achy us R.Br. of similar habit and when not in flower 
the two are almost indistinguishable.

Shipstern Range, on tracks through Eucalyptus - 
Casuarina forest, ca. 2,500 feet, March 25th, 1941, Blake 
14311 (tufted, erect, 6-1 Sin. , dull green; spikelets green 
to purplish). 
Later observations have shown that this attractive 
grass, which was previously known only from New South 
Wales, is rather common on Shipstern Range. The deter- 
mination has been verified by Miss Vickery, who revised 
the Australian species in the paper cited.
