13. CASSINIA, E. Br. 

 Involucre oblong, cylindric, or campanulate ; involucral bracts imbricate, 

 of few or many short obtuse oblong scarious or coloured scales, the innermost 

 with short radiating tips. Receptacle narrow, with scarious chaffy scales 

 amongst the florets. Florets tubular, the outer when present filiform, female ; 

 the inner hermaphrodite. Anthers short, tailed. Style long, terete, truncate, 

 glandular. Achenes usually papillose, short, angular or terete. Pappus-hairs 

 in 1—4 rows, slightly thickened at the tips, simple or barbellate. Shrubs, with 

 entire alternate leaves. Heads in terminal panicles or corymbs. 



A small genus, comprising about 20 species, of which about 14 are restricted to Australia,
