C. Drummondii. 
South-west Australia, Drummond, 1850.— A shrub apparently of con- 
siderable stature; the branchlets leafy to the top, terminated by solitary 
heads, which are nearly an inch in length. Leaves seldom an inch 
long, two lines wide, araneose beneath, the upper surface apparently 
somewhat viscous; the midrib impressed above and strongly prominent 
beneath; the lateral veins obscure, the surface of the leaf, in the dried 
specimens, somewhat bullate. The capitula are remarkable for their 
coriaceousse ales, greenish, with whitish margins, only the innermost, 
with their narrow radiant tips, being at all scarious. The pappus con- 
sists of much more rigid setze than those of Helichrysum. The name 
alludes to the (inversely) conical shape of the capitulum, called by 
Ehrhart an anthodium.
