loose and very white or tinged with pink but without spreading tips. Florets 

 about 20, a few outer ones sometimes female. Achenes glabrous or papillose.

Hab.: Burnett River, F. v. MiieUer ; Pine Biver, Fitzalan. A common southern shrub. 



17. K. cinereum (grey), F. v. M. Herb.; Benth. Fl. Austr. iii. 629. An 

 erect much-branched shrub of several feet, the branches tomentose. Leaves 

 linear, obtuse, rarely exceeding Jin., with revolute margins, not decui-rent, 

 glabrous above, tomentose underneath, sometimes very narrow, sometimes thick 

 and rather broad. Flower-heads small and numerous, in rather dense terminal 

 corymbs. Involuce at first ovoid, at length broadly turbinate, about 3 lines 

 long, the bracts rather numerous, appressed, often almost acute, the innermost 

 without any or with minute scarcely spreading white tips. Florets 15 to 20 or 

 rather more, a very few of the outer ones female. Achenes papillose. Pappus- 

 bristles serrulate, slightly thickened upwards. — Chrysocoma cinerea, Labill. PI.

18. H. cassinioides (Cassinia-like), Benth. Fl. Austr. iii. 629. An erect, 

 branching, heath-like shrub, the branches rather slender, tomentose. Leaves 

 harrow-linear, obtuse or with minute recurved points, above Jin. long, the 

 margins much revolute, not decurrent, glabrous and smooth above, tomentose 

 underneath. Flower-heads small and numerous, in small dense terminal 

 coryrribB. ■ InvaLucre narrow, about 2 lines long, the bracts scarious, concave, 

 appressed, without spreading tips. Florets about 12 to 16. Achenes glabrous. 

 Pappus -bristles scarcely thickened upwards.

34. CASSINIA, R. Br. 

 (After M. Henri Cassini.) 

 (Achromoltena, Cass.; Apaloehlamys and Ehynea, DC.) 

 Involucre narrow-ovoid or oblong, the bracts imbricate, scarious or coloured, 

 without any or, in species not Australian, with small radiating lamins. Eecep- 

 tacle with scarious chaffy scales between the florets. Florets few, all hermaphro- 

 dite, tubular, 5-toothed or, in species not Australian, a very few of the outer 

 ones slender and female. Anthers very shortly or obscurely tailed. Style- 

 branches nearly terete, truncate. Achenes short, angular or nearly terete, usually 

 papillose. Pappus of several simple entire or minutely denticulate capillary 

 bristles, in a single row and slightly cohering in a ring at the base. — Shrubs or 

 rarely herbs. Leaves alternate, entire. Flower-heads small, numerous, in 

 terminal corymbs or panicles. 



All the Australian species are endemic. The genus is closely allied to the small-headed 

 Helichrysa, with precisely the same habit, differing from it in the scales of the receptacle. A 

 few scales may indeed be occasionally found among the central florets of a few species of 



Helichrysum, especially when they are sterile, but in Oassinia they subtend the fertile florets. 



Benth. 



Shrubs with small or narrow rigid leaves. Florets under 10. 

 Corymbs dense, sessile and shorter than the upper leaves. Involucres 

 oblong ; bracts thinly scarious, very obtuse, without coloured tips, 

 shorter than the florets. Florets usually 4. Leaves lanceolate, smooth 

 above I, c. compacta.
