2. C. pleiocephala (heads many), F. v. M. in Linnaia, xxv. 404 ; Eenth. 

 Fl. Austr. iii, 580. Apparently annual, but rather robust, branching at the base 

 into erect or ascending stems, mostly simple, of about 1ft., more or less woolly- 

 hairy. Leaves lanceolate or linear, the lower ones petiolate, often 2in. long, the 

 upper ones sessile stem-clasping or decurrent. Cluster of flower-heads either 

 solitary terminal and globular, 4 or 5 lines diameter, or ovoid and ^ to fin. long, 

 and then often 2 smaller sessile ones close under it, each surrounded by lanceo- 

 late bracts with brown scarious margins, shorter than the florets, with a few 

 inner ones quite scarious, and similar subtending bracts within the cluster. 

 Beceptacle cylindrical. Partials heads 3 to 6-flowered. Involucral bracts and 

 scales of the partial receptacle scarious, with bright yellow tips, but scarcely 

 dilated into distinct laminae. Achenes silky-hairy. Pappus of several plumose 

 bristles. 



Hab.: Southern downs. 



3. C. chrysantha (golden-flowered), BentJi. Fl. Austr. iii. 580. A 

 perennial, branching at the base, with ascending or erect flowering stems, not 

 above 1ft. long, and more slender than in C. globosa. Leaves lihear, generally 

 becoming glabrous above, woolly-white underneath, the upper ones few, small, 

 and distant. Clusters of flower-heads terminal, globular or ovoid, not above ^in. 

 diameter, surrounded by few very small outer bracts, the subtending bracts within 

 the clusters narrow, brown but scarcely scarious, shorter than the florets, woolly 

 at the base. Eeceptacle oblong. Partial heads 4 to 6-flowered. Involucral 

 bracts and scales of the receptacle thin and transparent, obovate-oblong, shorter 

 than the florets. Pappus-bristles much more paleaceous than in 0. globoia, and 

 often here and there connate, scarcely plumose below the middle, very much so 

 towards the end, and bright yellow. — Calocephalus (?) cjirysanthus, Sohlecht.

Hab.: Southern downs. 



4. C. globosa (heads globose), Benth. Fl. Austr. iii. 580. Apparently 

 perennial, with erect, simple rigid stems of 1 to 3ft., silvery- white with a close 

 wool. Lower leaves oblong, linear, or lanceolate, often several inches long ; 

 upper ones few, small, and distant, all silvery-white on both sides. Clusters of 

 flower-heads solitary and terminal, globular, bright j'ellow, f to lin. diameter, 

 without any general involucre. Eeceptacle convex, hollow. Subtending bracts 

 within the cluster narrow and short, wooUy-eiliate as well as the receptacle. 

 Partial heads 6 to 8-flowered. Involucral bracts and scales of the receptacle 

 ovate or oblong, concave, very thin and transparent, with yellowish tips, but not 

 spreading. Pappus of 12 to 15 plumose bristles. — Pycnosorus globosus, Benth. in 

 Hueg. Enum. 67 ; DC. Prod. vi. 153. 



Hab.: Southern inland localities. 



48. CHTHONOCEPHALUS, Steetz. 



(So called from the heads of flowers appearing on the earth.) 



(Chamsasphserion, A. Gray ; Gryostephium, Tiircs.; Lachnothalamus, F. v. M.) 



Flower-heads numerous and sessile on a small receptacle, in a globular or 



depressed cluster or compound head, surrounded by a few more or less scarious 



or leafy bracts, forming an irregular general involucre. Partial heads few or 



many-flowered. Involucre of several scarious bracts, the outer ones rarely with 



leafy tips, and similar bracts or scales on the partial receptacle under each floret. 



Florets hermaphrodite, tubular, 4 or 5-toothed. Anthers more or less distinctly 



tailed, Style-branches nearly terete, truncate, Achenes usually somewhat
