South-western Australia, Drummond.— This little plant has the habit 
of Hyalochlamys, &e. The full-grown glomerules are nearly three lines 
broad. Leaves about the same length, apiculate, narrowly linear, or 
the larger linear-spatulate, dilated at the sessile base. The base of the 
corolla is not thickened in the specimens examined, which are young. 
There are-no full-grown acheenia. :
