1. p. rutidochlamys (involucral bracts wrinkled), F. c M. Vragm. iv. 79 ; 

 Benth. Fl. Amtr. iii. 603. An erect branching annual of 2 or 3ft., with more 

 or less of a loose deciduous wool. Leaves lanceolate or ovate-lanceolate, stem- 

 clasping with rounded auricles and often slightly decurrent. Flower-heads 

 nearly sessile and more or less clustered at the ends of the slender branches of a 

 loose panicle. Involucre ovoid, 4 to 5 lines long, the lamins of the bracts 

 imbricate, lanceolate, acuminate, transversely rugose, decurrent along the claws. 

 Female florets very few, not longer than the others, but more slender and only 

 8-lobed. Pappus-bristles rather numerous, scabrous or minutely barbellate. — 

 Rutidosis arachnoidea, Hook, in Mitch. Trop. Austr. 841 ; Rutidochlamys Mitchelli,

2. P. longipedata (peduncles long), A. Cunn. in DC. Prod. vi. 163 ; Benth. 

 FL Austr. iii. 604. Either annual or ^ith a perennial stock and annual stem of 

 1 to 2ft., simple or divaricately-branched and retaining very little cottony wool.

 heads smaller than in P. acuminata, pedunculate or rarely 3 or 4 together almost 

 sessile. Involucres hemispherical, about fin. or rarely nearly lin. diameter, the 

 scarious laminas of the bracts smaller than in all the allied species, ovate, obtuse 

 or acute, not rugose, those of the intermediate bracts much shorter than their 

 rather broad claws, a few of the outer bracts entirely scarious. Kay-florets as in 

 P. acuminata, yellow, longer than the others, ligulate or irregular, 3 or 4-lobed. 

 Pappus-bristles numerous, scarcely barbellate. — P. Mitchelli, Sond. in Linnsea,

 ceolate or linear, stem-clasping or rarely slightly decurrent. Flower-heads large, 

 yellow, pedunculate. Involucre hemispherical, 1 to l^in. diameter, the 

 scarious laminae of the bracts acute or acuminate, smooth and not rugose, the 

 inner ones on long linear claws. Florets all longer than the involucre, those of 

 the ray longer than the others, the limb ligulate or irregularly tubular, deeply 3 

 to 5-lobed. Pappus-bristles numerous, white, shortly barbellate, united at the 

 base. — DC. Prod. vi. 162 ; Hook. f. Fl. Tasm. i. 209; Scalia jaceoides, Sims.
