makes excellent hay. Like H. punctata, it has been introduced by 
travelling stock, either from Queensland or our own open country at 
the back. It is more plentiful probably than H. punctata, particularly 
around Lismore, so that any settler could secure a few plants by seeking 
some near the stone quarry. The grassis highly recommended to dairy 
farmers for systematic cultivation, either for permanent pasture or to 
eut for hay. Both the Hriochloas referred to in this paper are 
sufficiently vigorous to force a footing in old pastures, the seed 
springing into life from August to March.” 
Habitat and range.—Same as the preceding species. 
3. PANICUM. 
Spikelets with one terminal hermaphrodite and occasionally a male 
or rudimentary flower below it, rarely awned, variously arranged along 
the branches of a simple or compound panicle rarely reduced to a 
simple spike, the partial rhachis very rarely produced beyond the last 
spikelet ; barren awnlike branches none, or very rarely a single one. 
Glumes usually four, the outer one smaller than the others, not 
awned, often very small, deficient only in P. gibbosum, the second and 
third very variable in relative proportions, the third occasionally with 
a palea with or without three stamens in its axil; fourth or fruiting 
glume smaller, or as long as the third, of a firmer consistence, enclosing 
a palea and hermaphrodite flower. 
Styles distinct or very shortly united at the base. 
Grain enclosed in the hardened fruiting glume and palea, but free 
from them. 
Series J.—Dicirariez. 
Spikelets mostly in pairs along the outer and lower side of the 
simple slender branches of the panicle, one of each pair always 
pedicellate, the other sessile or on a shorter pedicel, the upper ones of 
each branch occasionally solitary, the lower ones very rarely clustered. 
Outer glume usually very small. 
Branches of the panicle often numerous, the lower ones long and 
verticillate, the upper ones scattered.
