able for the strong, spreading bristles, varying in size, in- 
deed, but most of them very large, with which almost every 
part of the plant is clothed. There is, however, an Austra- 
lian species, which seemed very nearly allied to this, the P. 
horridum of Dr Canpotie: whether distinct or not I am 
unable to say. 
Our plant flowered under a frame the latter end of May 
and beginning of June. Placed in the open border it 
seemed very susceptible of our (in this year, 1836) unusually 
cold and fickle summer. 
Descr. Root annual, or perhaps biennial. Stem erect, 
a foot and a half to two feet high, rounded, branched, 
clothed, as is every part of the plant, except the flowers) 
with copious, spreading, and very harsh bristles, unequal 
indeed, in size, but most of them very large. Leaves ob- 
long-lanceolate ; those of the root and lower part of the 
stem somewhat petiolate, pinnatifid, the segments distant, 
oblong-ovate, the margin every where toothed, the teeth 
bristle-pointed ; upper leaves sessile, inciso-serrate, gradu- 
ally smaller. Flowers scarcely two inches across, on hispid 
peduncles, which are somewhat panicled. Sepals two, oval, 
concave, hispid. Petals obovato-rotundate, somewhat 
clawed, very obtuse, wavy, pale brick-colour approaching 
to orange. Stamens numerous. Germen oblong, a little 
thickened upwards, slightly furrowed and torulose, quite 
glabrous. Stigma conico-depressed, of few rays. Capsule 
of the same shape with the germen, opening by large aper- 
tures beneath the stigma.
