(Flower-heads beautiful.) 



(Leucophyta, E. Br.; Paohysuius, Steetz ; Blennospora and Achrysum, A. Gniy.j 



Flower-heads numerous and usually more or less stipitate on a small and 

 branching or globose or conical receptacle in an ovoid or globular dense cluster 

 or compound head without any general involucre or surrounded by a few leafy or 

 scarious bracts rarely exceeding the florets. Partial heads 2 or more-flowered. 

 Involucre of several bracts, the outer ones like the subtending ones narrow and 

 often more persistent, the inner ones broader transparent and very deciduous. 

 Receptacle without scales. Florets hermaphrodite, tubular, 5-toothed, not at all 

 or scarcely hardened at the bsise. Anthers more or less distinctly tailed. Style- 

 branches nearly terete, truncate. Achenes usually compressed. Pappus of 

 several narrow linear scales or bristles plumose-ciliate from the base or at the end 

 only, all free or united in a ring at the base. — Annual or perennial herbs or rarely 

 undershrubs or small shrubs, more or less cottony or woolly, white or rarely 

 glabrous. Leaves alternate or in two species opposite, entire. Clusters of 

 flower-heads terminal, sessile or pedunculate. 



The genus is limited to Australia. It is very near to Gnepltosis, differing chiefly in the 

 pappus. The general receptacle is also sometimes broken up or slightly branched, the partial 

 heads are thus more distinct and having often more florets connect the genus through 

 Gephalipterwm and Gnaphalodes with llelipterum. — Binth. 



Partial heads 2 or 3-flowered. 



Leaves alternate, Pappus plumose at the end. Involucral bracts with 

 small petal-like appendages 1. C. Sonderi. 



Leaves mostly opposite, mostly acute. Pappus plumose chiefly at the 



end. Clusters of flower-heads yellow . 2. C. citreus. 



Partial heads 6 or more flowered. 



Clusters of flower-heads dense and globular. Appendages of the in- 

 volucral bracts radiating round the partial heads. Leaves scattered, 

 linear-obtuse. Pappus of a few laxly-plumose intricate bristles . . S. C. Diltrichii. 



Clusters of flower-heads loose, terminal, the heads distinctly stipitate. 

 Involucral bracts without any or with very small appendages. Pappus 

 of woolly-plumose hair-like bristles, distinct. Leaves narrow-linear. 

 Perennial or undershrub . 4. C. platycephahM. 



1. C. Sonderi (after Dr. 0. W. Bonder), F. r. M. Rep. Babb. Exped. 13 ; 

 Benth. Fl. Austr. iii. 575. An erect branching loosely woolly annual with a hard 

 stem, attaining sometimes above 1ft. in height. Leaves alternate, linear, the 

 upper ones short and decurrent. Clusters of flower-heads yellow, ovoid or 

 globose, rarely 5 lines long. Receptacle cylindrical, branched. Partial heads 

 stipitate, 2 or 3-flowered. Subtending and outer involucral bracts 2 or 3, in the 

 lateral heads more numerous, in the terminal one narrow but scarious and 

 wooUy-eiliate with a small lamina or appendage, a few inner ones broader, less 

 ciliate, with a more prominent yellow lamina. Pappus of several - very unequal 

 scales united in a ring or cup at the base, and more or less produced into awns or 

 bristles of which the longer ones are plumose at the end.
