Australian Plants. 45 
brownish; pappus ciliate-torn, shorter than the akenium, or 
producing a single hair, which is not plumose at the summit, 
and shorter than the corolla. 
On barren plains near Swanhill. 
Although the above notes appear to offer the only distine- 
tive marks between this and Ang. tomentosus, the only hitherto 
know species, yet this new one may be most easily recognised 
by them. 
36. Heckeria ozothamnoides. 
Branches scantily woolly ; leaves linear, mucronate, with 
revolute margin, beneath grey-tomentose ; heads 5-7- 
flowered; all scales of the involucre upwards pale-yellow. 
In dry places on Barker’s Creek, on the Upper Murray and 
Snowy River. 
The species upon which I founded the genus originally 
may be briefly thus characterized. 
Hecheria cassinieformis. 
Leaves semiterete, blunt, as well as the branches scabrous ; 
heads 2-3-flowered; interior scales of the involucre upwards 
white. 
37. Antennaria, Gaertner. 
(Sect. Actina.) 
Scales of the involucre radiating. Heads of the fertile 
plants with several rows of female flowers in circumference, 
and with hermaphrodite ones in the centre. Heads of the 
sterile plants with only hermaphrodite flowers, a few rarely 
fertile. Pappus at the extremity clavellate, with exception 
of that of the female flowers, which is not thickened. 
Antennaria nubigena, 
Stems herbaceous, creeping, corymbose, short, upright, 
cespitose; leaves dense, flat, oblong or ovate-cuneate, some- 
what acute, entire, spreading, clasping at the base, one-nerved, 
on both sides covered with a thin appressed silver-grey 
toment; flowerheads terminal, generally solitary, sessile; 
inyolucres hemispherico - campanulate; its scales smooth, 
acute, entire, the middle ones lanceolate - oblong, white at 
the top; akenia tereti-oblong, scabrous.
