merulis junioribus dense lanatis folioso-bracteatis. (Hook. Ie. Pl, 
tab. ined.) l 
South-western Australia, Drummond, 1850.—Stems one or two inches 
long, spreading on the ground, soon glabrous. Glomerule turbinate, 
2 lines long. The narrow paleate scales of the general receptacle ap- 
pear to persist after the capituli they subtend fall away. Tube of the 
corolla longer than the infundibular-campanulate limb, its base much 
dilated, and covering the apex of the ovary and achænium, thickened, 
and just at its insertion bearing a ring of very long and delicate simple : 
woolly hairs, more than half the length of the corolla, and exactly imi- | 
tating a fine pilose pappus. The attenuate base of the turbinate achzenium — : 
is tipped with a small callus, nearly as in 5. Preissianus. I think the = 
ring of hairs belongs to the base of the corolla, and not to the achænium 
(as it does in Pachysurus, Steetz), but the two are so firmly coalescent 
that, when pulled asunder, the vertex of the achænium usually comes 
off with the thickened base of the corolla, like a lid, opening the peri- 
carp by a clean cireumscission, and exposing the seed ! :
