general habit it comes nearest to C. tinctoria and Atkinso- 
niana; and is, perhaps, as it were, intermediate between 
them and C. verticillata, having broader and less divided 
leaves than the former, and more flaccid foliage and stems, 
and a very different inflorescence from the latter. It 
appears to be annual or biennial, and flowers in the open 
border in the autumn. 
Descr. Stems erect, but weak and flexuose, succulent, 
striated, glabrous, having many straggling and wavy 
branches. Leaves opposite and connate at the base, very 
variable : the lowermost ones entire, the rest more or less 
pinnatifid or even bipinnatifid, with the segments from 
three to five, rarely more, linear-lanceolate, flaccid, gla- 
brous, generally curved, glabrous, strongly ciliated at the 
base, which forms a kind of broad petiole ; and, when seen 
under a lens, the rest of the margin exhibits minute hairs. 
Peduncles very long, flexuose, naked, or rarely with an un- 
divided leaf, single-flowered. Involucre glabrous ; outer of 
about eight spreading, ovato-lanceolate, green, acute leaves, 
diaphanous and ciliated at the margin: znner of about as 
many erect, ovate, obtuse, membranaceous, yellow-brown 
leaves. Florets all full yellow: those of the ray oblong- 
obovate, with five deep, unequal teeth at the extremity : 
their germen abortive, flat, but having a pappus of two 
minute, plumose scales. Tubular or central floret yellow. 
Fruit (immature) compressed, winged, crowned with small, 
flat, ciliated awns or scales.
