brownish; pappus cUiate-torn, shorter than the akenium, or 

 producing a single hair, ^Yhich is not plumose at the summit^ 

 and shorter than the corolla. 



On barren plains near Swanhill. 



Although the above not<3s appear to offer th^ only^ distinc- 

 tive marks between this and Ang. tomentosus, the only hitherto 

 know species, yet this new one may be most easily recognised 

 by them. 



36. HcBckeria ozothamnoides. 



Brandies scantily woolly ; leaves linear, mucronate, with 

 re volute 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 Blver. 



The species upon which I founded the genus originally 

 may be briefly thus characterized. 



Hceckeria cassinmformis. 



Leaves semiterete, blunt, as well as the branches scabrous; 

 heads 2-3-flowered ; interior scales of the involucre upwards 

 white.

 plants with several rows of female flowers in circumference, 

 and with hermaphrodite ones in the centre. Heads of the

 fertile. Pappus at the extremity clavellate, with exception 

 of that of the female flowers, which is not thickened.

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,
